Description

Method for establishing an operation model of a sun-chasing solar energy system based on demand response

The present invention relates to a method for establishing a solar system operation model, and in particular to a method for establishing a model that can adjust the operation decision of solar panels under different levels of demand response conditions.

Solar energy is the mainstream renewable energy in modern times. Since it does not consume resources in the process of producing electricity and does not cause environmental pollution, it can truly achieve the effects of environmental protection, sustainability, and reducing carbon emissions. Among them, in the existing solar power generation devices or systems, the main technical emphasis is on improving the efficiency of power production, so the direction of its technical development will focus on the timeliness and accuracy of "sun tracking". However, there is no relevant technology to disclose the control between the solar tracking system and the power supply capacity of the power supply system. It can be understood that if there is an imbalance between the power consumption and energy storage supply or the external power supply in the power grid where the solar tracking system is located, it may cause the power grid or microgrid safety mechanism to be opened, causing the solar battery to be powered off and the power supply and output to be interrupted. This result will cause significant losses to the power supply or demand side. Therefore, in view of the above problems, it is necessary to provide a method that can simultaneously consider the proportional relationship between the power supply and power consumption in the power grid to adjust the operation strategy of the solar energy system in the same power grid.

The problem that the present invention aims to solve is to provide a method for establishing a solar system operation model that can determine the maximum power generation and maximum power consumption of the battery module of the solar panel in each time unit, so as to adjust the operation strategy of the solar panel according to the ratio of the actual or estimated total power consumption of the grid load (defined as P) to the rated value of energy available in the grid.

If so, proceed to step (L6); if not, the control unit controls the solar panel to follow the moving trajectory of the sun in the time interval to rotate the horizontal angle or the pitch angle, and waits for the extension time before proceeding to step (L2); and (L6) keeps the solar panel stationary for a buffer time, and then proceeds to step (L2).

The present invention further provides a method for establishing an operation model of a solar tracking system based on demand response, comprising the following steps: (K1) at least one solar tracking system is installed in a power grid, wherein: the power grid includes an electric energy management system; and the solar tracking system includes a control unit and a solar panel, which is electrically connected to the control unit; (K2) the electric energy management system compares the actual power consumption of the power grid with its negative power consumption at each time interval.

After a long time, step (K2) is re-executed; when the output result received by the control unit is B, the control unit controls the solar panel to follow the movement trajectory of the sun within the time interval and rotate a horizontal angle or a pitch angle, and waits for the extended time before re-executing step (K2); and when the output result received by the control unit is C, the solar panel is kept stationary and continues for a buffer time before re-executing step (K2).

Since the relevant parameter conditions and the mathematical equations of the recursive fuzzy neural network have been explained above, no further details will be given here.

The effectiveness of the present invention over the prior art is that in the existing solar system operation model, only the light-receiving area of the solar panel and the angle at which the solar panel receives light are considered to increase the power generation of the battery module. Therefore, it is understandable that the focus of the prior art is on improving the "energy storage" efficiency of the solar system. However, when the battery module consumes electricity while storing energy, if the power load of the battery module is greater than the rated power of the load, it may cause its internal protection mechanism to open and forcibly cut off the power supply. This will result in the interruption of the battery module's energy storage and power supply process, and cause the machinery or equipment based on solar energy to stop operating, affecting the industry's production capacity or yield. In summary, in order to ensure that the energy storage and energy consumption of the solar energy system can operate stably, it is necessary to reduce the power consumed by the solar energy system itself when the power load of the battery module exceeds a certain threshold value to reduce the burden on the battery module. The method provided by the present invention can use a multi-layer judgment mechanism to make the corresponding operation strategy when the power load of the battery module reaches different load ratings to prevent power outages caused by imbalanced supply and demand of the battery module, and can also improve the service life and safety performance of the battery module.

The number of times when the threshold value A is reached, _Q2 is the threshold value C> the actual power consumption

The number of times when the threshold value B is reached; (S5) judging whether the sun has set or the set end-of-sun tracking time or angle has been reached according to the sun's moving trajectory? If so, the solar panel (1) is reset to an initial position; if not, proceeding to step (S6); (S6) judging whether the actual power consumption is

The threshold value A? If yes, proceed to step (S7); if no, the solar panel (1) follows the movement trajectory of the sun within the measurement time and rotates a horizontal angle and a pitch angle, and after returning the counts of _Q1 and _Q2 to zero, proceed to step (S4); (S7) determine whether the actual power consumption is

The threshold value B, wherein the threshold value B> the threshold value A? If so, proceed to step (S8); if not, the solar panel (1) follows the movement trajectory of the sun within the measurement time to rotate the horizontal angle and the pitch angle, and waits for the extension time before proceeding to step (S4); (S8) determines whether the actual power consumption is

The threshold value C, wherein the threshold value C> the threshold value B? If so, proceed to step (S9), if not, the solar panel (1) follows the movement trajectory of the sun within the measurement time to rotate the horizontal angle or the pitch angle, and waits for the extension time before proceeding to step (S4); and (S9) the solar panel (1) is kept stationary for a buffer time, and then proceeds to step (S4). Specifically, the reference time is the shortest time for measuring the actual power generation and the actual power consumption each time step (S4) is performed, and the extension time is the length of time for each overtime.

Preferably, in order to implement a corresponding energy-saving strategy according to the ratio of the power loss of the battery module to its load rating, so as to avoid the actual power consumption being greater than or equal to the load rating of the battery module, thereby causing the charging and discharging system of the battery module to be disconnected or malfunction, wherein: the threshold value A is 60% to 80% of the load rating of the battery module %, preferably 65% to 75%, more preferably 70%; the threshold value B is 70% to 90% of the load rating of the battery module, preferably 75% to 85%, more preferably 80%; and the threshold value C is 80% to 99% of the load rating of the battery module, preferably 85% to 95%, more preferably 90%, but not limited thereto. Specifically, the "load rating" refers to: the maximum value of the electric energy that the management system of the power grid or microgrid can provide at the moment or in the next time interval; or the consumption of the energy storage system. For example, when the actual power consumption reaches 90% of the load rating of the battery module, it means that within a unit of time, 90% of the power generated by the solar panel (1) and stored in the battery module is consumed, and only the remaining 10% is stored in the battery module.

門檻值A時，此時適當地延長測定時間，以減緩電池模組耗電量的負載壓力；當門檻值C>W

門檻值B時，此時同時延長測定時間，並使太陽能板(1)的運轉策略進行「降級」，使雙軸運轉更改為單軸運轉、 或使單軸運轉更改為不運轉，以更進一步地減緩電池模組耗電量的負載壓力；以及當W

門檻值C時，此時表示電池模組的真實耗電量已經非常接近，且隨時有可能超過負載額定值，因此，此時不可讓太陽能板(1)進行運轉、或重新進行真實發電量、或真實耗電量的測定，而是使太陽能板(1)維持靜止，並等待電池模組的真實耗電量相對於負載額定值之比例下降至一安全區間後，再重新回到步驟(S4)，並重新進行判定流程。 Preferably, in the above step (S7) or step (S8), the purpose of making the solar panel (1) wait for a longer time is to reduce the frequency of operation of the maximum power generation prediction module and the power consumption sensing module. Specifically, each time the real power generation or real power consumption of the battery module is detected, the maximum power generation prediction module or the power consumption sensing module will consume a fixed amount of power in the battery module. Therefore, it can be understood that each time the maximum power generation prediction module or the power consumption sensing module is running, it will cause The ratio of the actual power consumption of the battery module to its load rating increases. If the energy consumption of the device connected to the battery module suddenly increases, it is very likely that the instantaneous actual power consumption of the battery module will suddenly exceed its load rating, causing the internal protection mechanism of the battery module to open and cut off the energy storage and energy consumption channels. This result not only requires the power supplier to consume manpower and material resources to adjust and restart the solar energy storage device, but also affects the production schedule or quality control of the power user, greatly affecting the production capacity. The present invention sets a three-level control procedure. Assuming that the actual power consumption is W, when the threshold value B>W

When the threshold value is A, the measurement time is appropriately extended to reduce the load pressure of the battery module power consumption; when the threshold value is C>W

When the threshold value is B, the measurement time is extended at the same time, and the operation strategy of the solar panel (1) is "downgraded" to change the dual-axis operation to single-axis operation, or change the single-axis operation to non-operation, so as to further reduce the load pressure of the battery module power consumption; and when W

When the threshold value C is reached, it means that the actual power consumption of the battery module is very close to and may exceed the load rating at any time. Therefore, the solar panel (1) cannot be operated or the actual power generation or actual power consumption cannot be re-measured. Instead, the solar panel (1) is kept stationary and the ratio of the actual power consumption of the battery module to the load rating is waited to drop to a safe range before returning to step (S4) and re-performing the determination process.

Preferably, in order to obtain sufficient illumination data of the photosensitive element to optimize the maximum power generation prediction module so that it can more accurately measure the power generation of the solar panel (1), or in order to enable the maximum power generation prediction module to measure the maximum power that the "actual" solar panel (1) can generate without making the measured value too idealized and causing a large deviation from the actual value, wherein: in step (S2), the relevant parameter conditions include: a system of relevant parameters, It is selected from the following parameter group, or a combination thereof: the voltage of the solar panel (1), the current of the solar panel (1), the temperature of the solar panel (1), the total irradiance of the solar panel (1), the voltage of the battery module, the current of the battery module, the temperature of the battery module, the total irradiance of the battery module, a horizontal angle of the solar panel (1) relative to the initial position, and a pitch angle of the solar panel (1) relative to the initial position.

In a preferred embodiment, the placement time can be 1 day to 1 year, but is not limited to this. When only one set of illumination data of the photosensitive element is used to obtain the maximum power generation prediction module, a longer placement time is required to maintain the accuracy of the maximum power generation prediction module in measuring the power generation of the solar panel (1); however, when multiple sets of illumination data of the photosensitive element are used to form the maximum power generation prediction module at the same time, the placement time can be greatly shortened, and the maximum power generation prediction module can accurately measure the power generation of the solar panel (1). In another preferred embodiment, the placement time is one day, one week, one month, one quarter, half a year, multiples of the above time units, or a combination of the above time units, but is not limited thereto.

The number of times when the threshold value B is reached; (P5) According to the movement trajectory of the sun, is it determined whether the sun has set, or the time or angle for ending the sun tracking has been reached? If so, the solar panel (1) is reset to an initial position; if not, the process proceeds to step (P6); (P6) Is the actual power generation greater than a minimum power required for operation? If so, the process proceeds to step (P7); if not, the solar panel (1) does not rotate, and the process proceeds to step (P4); (P7) Is it possible to reduce the shaded area on the surface of the solar panel (1) when the solar panel (1) rotates?

If so, proceed to step (P10); if not, determine which way the solar panel (1) is rotated in a single axis or a double axis to remove more shaded area, and according to the way to obtain the highest power generation, make the solar panel (1) rotate along the moving track of the sun within the measurement time to the position where the light receiving area of the solar panel (1) is the largest, and wait for the extension time before proceeding to step (P4); (P10) determine whether the actual power consumption of the battery module is

The threshold value C, wherein the threshold value C> the threshold value B? If so, proceed to step (P11); if not, determine in which way the solar panel (1) is rotated in a single axis or in a dual axis to remove more shaded area, wherein: if it is a single axis rotation, the solar panel (1) does not rotate, and returns to step (P4); and if it is a dual axis rotation, determine in which way the solar panel (1) is rotated in a horizontal angle or in a pitch angle. The rotation can remove more shaded areas, and in a manner that can obtain the highest power generation, the solar panel (1) is rotated along the movement trajectory of the sun within the measured time to the position where the light receiving area of the solar panel (1) is the largest, and after waiting for the extended time, the step (P4) is entered; and (P11) the solar panel (1) is kept stationary for a buffer time, and the step (P4) is entered. In a preferred embodiment, the minimum power required for operation is 30 to 80% of the maximum power generation that the solar panel can generate when the photosensitive element is not shaded, but is not limited thereto. Among them, the difference between this embodiment and the above-mentioned embodiment is only whether the shading state is taken into consideration, and the other parts are roughly similar, so no further elaboration is made here.

More preferably, when considering the rotation decision of the solar panel (1) when it is shaded, the adjustment basis includes the following four implementation modes. Among the four implementation modes, with reference to FIG. 3A, the solar panel (1) needs to be rotated horizontally to the left or vertically upward so that its rotation trajectory conforms to the movement path of the sun. In the "first implementation", as shown in FIG3A, it can be found that the photosensitive elements (2) on the right half of the solar panel (1) are all shielded by a shade area (3), and the shade area (3) extends to the right half of the solar panel (1). Therefore, in order to maximize the illumination area of the solar panel (1) to increase the power generation, the horizontal angle (azimuth) of the solar panel (1) should be changed to rotate relative to the shade area (3). Therefore, the best rotation decision is to rotate horizontally to the left. As shown in FIG3B, it can be found that: after the solar panel (1) rotates horizontally, the photosensitive elements (2) on the right half of the solar panel (1) can receive light to increase the power generation of the solar panel (1). In the "second implementation", as shown in FIG4A, it can be found that the photosensitive elements (2) in the lower half of the solar panel (1) are all shielded by a shade area (3), and the shade area (3) extends to the lower half of the solar panel (1). Therefore, in order to maximize the illumination area of the solar panel (1) to increase the power generation, the pitch angle of the solar panel (1) should be changed to rotate it relative to the shade area (3). Therefore, the best rotation decision at this time is to rotate it vertically upward. As shown in FIG4B, it can be found that: after the solar panel (1) is rotated in the vertical direction, the photosensitive elements (2) in the lower half of the solar panel (1) can receive light to increase the power generation of the solar panel (1). In the "third implementation", as shown in FIG. 5A, it can be found that the right half of the solar panel (1) and the photosensitive element (2) in the lower half are both shielded by a shade area (3), and the shade area (3) extends to the right half and the lower half of the solar panel (1). Therefore, in order to maximize the irradiation area of the solar panel (1) to increase the power generation, the azimuth and pitch angles of the solar panel (1) should be changed at the same time so that it rotates relative to the shade area (3). Therefore, the best rotation decision at this time is to rotate to the left horizontally and to the upper vertically at the same time. As shown in FIG. 5B , it can be found that: when the solar panel (1) is rotated in the horizontal and vertical directions at the same time, the right half of the solar panel (1) and the photosensitive element (2) in the lower half can receive light, thereby increasing the power generation of the solar panel (1). In the "fourth embodiment", as shown in FIG. 6 , it can be found that the left half of the solar panel (1) and the photosensitive element (2) in the upper half are both shielded by a shade area (3), and the shade area (3) extends to the left half and the upper half of the solar panel (1). Therefore, if the solar panel (1) is rotated at this time, it will cause the solar panel (1) to move toward the shade area. The region (3) moves, so that the light receiving area of the solar panel (1) decreases. Since the power generated by the solar panel (1) after the rotation is lower than the power generated before the rotation, in order to avoid unnecessary energy consumption, the rotation strategy of the solar panel (1) is not to rotate, and returns to step (S4). After another time unit has passed, the rotation decision is re-determined. Among them, although in the fourth embodiment, the solar panel (1) can be rotated horizontally to the right and vertically downward to increase the light receiving area of the solar panel (1), its rotation direction will be opposite to the actual movement trajectory of the sun, causing a large deviation in the solar irradiation angle and causing the power generation of the solar panel (1) to be greatly reduced. Therefore, in order to avoid the above situation, in the rotation strategy of the solar panel (1), its rotation direction must follow the actual movement trajectory of the sun to rotate, so that the solar panel (1) can stably store energy in both the shaded state and the non-shaded state.

Preferably, the device further comprises a monitoring mechanism disposed on the solar panel (1) for obtaining a geographical coordinate position of the solar panel (1) and calculating the elevation angle and azimuth angle of the sun's illumination of the geographical coordinate position at each moment to obtain solar illumination angle information, so that the solar panel (1) can move accordingly according to the solar illumination angle information, so that the solar panel (1) can receive direct sunlight and generate high power. Specifically, under full sunlight and no shadow environment conditions, the solar panel (1) will rotate horizontally and vertically according to the solar radiation angle information after each unit time, so that the solar panel (1) remains perpendicular to the solar radiation angle to generate the maximum power generation. In addition, when the solar panel (1) is affected by the shade, if the power generation that the solar panel (1) can currently generate is lower than the power required to rotate the solar panel (1), it means that operating the solar panel (1) will cause the total power generation to decrease, and it is not appropriate to rotate the solar panel (1) at this time; if the power generation that the solar panel (1) can currently generate is higher than the power required to rotate the solar panel (1), it means that operating the solar panel (1) will cause the total power generation to decrease, and the solar panel (1) should not be rotated at this time; if the power generation that the solar panel (1) can currently generate is higher than the power required to rotate the solar panel (1), it means that operating the solar panel (1) will cause the total power generation to decrease, and the solar panel (1) should not be rotated at this time. When the power is calculated, it can be calculated: when the solar panel (1) rotates horizontally, vertically, or rotates in both horizontal and vertical directions according to the solar illumination angle information, which operation mode can maximize the increase of the light-receiving area on the solar panel (1), and according to the rotation mode that can maximize the increase of the light-receiving area, the solar panel (1) is rotated according to the solar illumination angle information. Specifically, the present invention takes into account the problem of low power generation that may be encountered when the solar panel (1) operates in various shading modes, and maximizes the power generation of the solar panel (1) and prevents the power stored in the solar battery from being lost due to improper operation of the solar panel (1). In a preferred embodiment, the monitoring mechanism can adjust the azimuth and elevation angle of the solar panel (1) to generate the highest power point under the current solar irradiation position, so that the solar panel (1) can continuously generate the highest power when rotating along the sun's moving trajectory. In another preferred embodiment, the geographic coordinate position is a two-dimensional coordinate system composed of longitude and latitude, or a three-dimensional coordinate system composed of longitude, latitude, and altitude, but is not limited thereto.

More preferably, in step (P5), a tracking device is installed on the solar panel (1), and the tracking device is used to track the current position of the sun to confirm whether the solar panel (1) is in a state where it can receive light. Specifically, when the solar panel (1) is only in a shaded state and does not generate power temporarily, since the sun can still shine on the solar panel (1) after the shaded part disappears, it is in a "light-receiving state". At this time, since the solar panel (1) does not generate power, if the solar panel (1) is rotated, the total power in the solar battery will decrease. Therefore, the rotation strategy of the solar panel (1) is not to rotate, and return to step (P4) to wait for a measured time again. , and then re-determine the power generation; and when the solar panel (1) does not generate power because the sun has set, the solar panel (1) cannot receive sunlight, which is a certain and unchangeable matter, so it is in a "state that cannot receive light". In addition, since the sun sets, it means that the solar panel (1) has completed the process of chasing the sun for a day. In order to enable the solar panel (1) to chase the sun again the next day, when the solar panel (1) is in a state that cannot receive light, it will automatically reset to the initial position. In a preferred embodiment, after the solar panel (1) is reset to the initial position, it will sleep for a period of time and restart when it is close to sunrise to reduce the power consumption during the standby time.

More preferably, "single-axis rotation" means: rotating the solar panel (1) by an azimuth angle of a horizontal angle unit, or rotating the solar panel (1) by an elevation angle of a vertical angle unit; and "double-axis rotation" means: rotating the solar panel (1) by an azimuth angle of a horizontal angle unit, and by an elevation angle of a vertical angle unit, respectively. Wherein: when the power consumption sensing module senses that the power consumption of the battery module reaches a certain threshold of the load rating, the rotation strategy of the solar panel (1) will be "downgraded", that is, the single-axis rotation is changed to non-rotation, and the double-axis rotation is changed to single-axis rotation, so as to reduce the load of the battery module, avoid a sudden increase in power consumption causing the power consumption of the battery module to exceed the upper limit of its load rating, and automatically start the safety system inside the battery module, causing the input end and the output end of the battery module to be powered off at the same time. In a preferred embodiment, the horizontal angle unit or the vertical angle unit is 1 to 20°, but is not limited thereto.

If so, proceed to step (L6); if not, the control unit controls the solar panel (1) to follow the moving trajectory of the sun in the time interval to rotate the horizontal angle or the pitch angle, and waits for the extension time before proceeding to step (L2); and (L6) keeps the solar panel (1) in a stationary state for a buffer time, and then proceeds to step (L2). Specifically, the power grid can be a power plant or a power supply station, wherein the load rating that the power grid can supply at the moment or in each time interval in the power grid where the solar tracking system is located, and the percentage of the power consumption relative to the load rating is determined in which range of threshold values A to C, so as to adjust the operation strategy of the solar panels (1) in the solar tracking system and regulate the power consumption in the entire power grid, so that the power grid can stably supply power to the solar tracking system, or the solar tracking system can stably supply power to the electrical components connected thereto without causing power outages. In a preferred embodiment, the threshold value A is 60% to 80% of the rated energy available in the power grid, the threshold value B is 70% to 90% of the rated energy available in the power grid, and the threshold value C is 80% to 99% of the rated energy available in the power grid, but is not limited thereto.

Another object of the present invention is to provide a method for establishing an operation model of a solar tracking system based on demand response, which, as shown in FIG8, comprises the following steps: (K1) at least one solar tracking system is installed in a power grid, wherein: the power grid comprises an electric energy management system; and the solar tracking system comprises a control unit and a solar panel (1) which is electrically connected to the control unit; (K2) the electric energy management system transmits the real power of the power grid to the control unit at each time interval.

The benefit of the present invention over the prior art is that in the existing solar system operation model, only the light receiving area of the solar panel (1) and the angle at which the solar panel (1) receives light are considered to increase the power generation of the battery module. Therefore, it is understandable that the focus of the prior art is on improving the "energy storage" efficiency of the solar system. However, when the battery module consumes electricity while storing energy, if the power load of the battery module is greater than the rated power, its internal protection mechanism may be activated and the power supply may be forcibly cut off. This will result in the interruption of the battery module's energy storage and power supply process, and cause the machinery or equipment based on solar energy to stop operating, affecting the industry's production capacity or yield. In summary, in order to ensure that the energy storage and energy consumption of the solar energy system can operate stably, it is necessary to reduce the power consumed by the solar energy system itself when the power load of the battery module exceeds a certain threshold value to reduce the burden on the battery module. The method provided by the present invention can use a multi-layer judgment mechanism to make the corresponding operation strategy when the power load of the battery module reaches different load ratings to prevent power outages caused by imbalanced supply and demand of the battery module power, and can also improve the service life and safety performance of the battery module.
