In modern society, the stability and continuity of the power supply is critical to the proper operation of the various devices. However, conventional power supply systems often face a number of significant challenges, such as supply and demand imbalance, peak power loads, and the like. These problems not only lead to reduced operating efficiency of the power system, but also may cause damage to the terminal equipment. To address these issues, joint energy storage systems are becoming more and more widely used. These systems can store energy during periods of low power demand and release energy during periods of high power demand, thereby balancing power supply and demand and relieving peak power loads.
However, the combined energy storage system is not without problems in practical applications. The power supply strategy of the combined energy storage system adopts a one-to-one mode, namely one energy storage device in the combined energy storage system corresponds to one terminal device. There are some potential problems with this one-to-one power mode. Firstly, when the electric quantity of the energy storage equipment is insufficient, power cannot be supplied to the corresponding terminal equipment, so that the power consumption requirement of the terminal equipment cannot be met. This may lead to a failure of the terminal equipment to function properly, even if it is shut down or damaged, and it is difficult to meet the rapidly changing power demand.
In order to solve the above technical problems, the present application provides an energy distribution method for a combined energy storage system, and referring to fig. 1, fig. 1 is a flow chart of an energy distribution method for a combined energy storage system according to an embodiment of the present application. The energy distribution method is applied to a management platform in a combined energy storage system, and comprises the following steps of S110 to S140:
s110, receiving a load demand sent by the terminal equipment, wherein the load demand comprises electricity consumption, and the load demand is used for representing the demand of the electricity consumption required by the terminal equipment.
Specifically, the management platform first receives the load demand sent by the terminal device, and the receiving process is real-time receiving. The management platform is used for managing and monitoring the use of energy, and can coordinate and adjust the supply and the demand of the energy so as to ensure the stability and the efficiency of the combined energy storage system. Terminal devices refer to various devices that require power to operate, such as computers, cell phones, appliances, and the like. The load demand means the desire of the terminal device for power demand. Such demands may arise from the workload of the device, e.g., a running computer or television, or a particular task, e.g., starting up a high power device.
For example, assume that a combined energy storage system includes a solar panel, a battery, and a wind generator. In this system, the user's mobile phone as a terminal device sends its load demand to the management platform, so that the management platform knows that the terminal device is running an application program requiring a lot of power, or that it is about to perform an operation of consuming power, such as starting video recording.
S120, acquiring operation parameters of first energy storage equipment, wherein the operation parameters comprise current temperature and residual electric quantity, and the combined energy storage system comprises a plurality of energy storage equipment, and the first energy storage equipment is energy storage equipment which supplies power for terminal equipment in the plurality of energy storage equipment.
Specifically, after receiving a load demand sent by a terminal device, according to a preset corresponding relationship between the terminal device and an energy storage device, the management platform can learn that the energy storage device corresponding to the terminal device is a first energy storage device. Next, the management platform will acquire the operation parameters of the first energy storage device, so as to acquire the current temperature and the residual electric quantity of the first energy storage device. The operation parameters refer to state parameters of the first energy storage device, wherein the state parameters comprise the current temperature and the residual electric quantity. The current temperature may represent an internal temperature of the energy storage device such as a battery or a capacitor, and the remaining power represents the power remaining in the energy storage device, for knowing the time during which the device may continue to supply power. The energy storage system is composed of a plurality of energy storage devices, and the plurality of energy storage devices can be batteries, super capacitors, fuel cells, solar panels and the like.
Further, the operating parameters may also include a charge-discharge status, indicating whether the energy storage device is being charged or discharged, which is important for understanding the current power status of the energy storage device and predicting its future power supply capability, charge-discharge efficiency, indicating the efficiency of charging or discharging the device, which may help optimize the management of power supply and demand, charge-discharge times, indicating the number of times the device has been charged or discharged, which may help to understand the life and performance degradation of the device, maximum charge-discharge power, indicating the power that the device may be maximally charged or discharged, which may help to optimize the management of power supply and demand, run time, indicating the time that the device has been operated, which may help to understand the efficiency and life of the energy storage device, environmental factors, such as ambient temperature, ambient humidity, pressure, etc., which may affect the performance and life of the energy storage device. It should be noted that, in the embodiment of the present application, the current temperature of the energy storage device is mainly considered, and other parameters are not limited, which is not repeated here. Acquiring these operating parameters may help the management platform to better understand the status of the first energy storage device for more efficient energy management. For example, if the management platform knows that the temperature of a certain device is too high, it may need to take measures to reduce the temperature to prevent the device from overheating and reduce its performance. Meanwhile, through the knowledge of the residual electric quantity, the energy management platform can better predict and manage the electric power supply so as to ensure that the terminal equipment obtains stable electric power supply.
In one possible implementation, the method comprises the steps of receiving an operation parameter data packet sent by a sensor group, wherein the sensor group is used for measuring operation parameter data of the first energy storage device, and preprocessing the operation parameter data packet to obtain the operation parameter of the first energy storage device, and the preprocessing comprises data cleaning, data classification and normalization processing.
Specifically, the above process is a specific process of obtaining, by a management platform, an operation parameter of a first energy storage device according to an embodiment of the present application. The management platform receives the operational parameter data packets sent by the sensor group, which means that the management platform receives the operational parameter data packets sent from the sensor group in some way, which may be a network connection, a physical interface, etc. The data packets include information about the operating parameters of the first energy storage device, such as the current temperature, the remaining power, etc. These packets may be sent in different formats, such as JSON, XML, etc., or in different protocols, such as Modbus, zigbee, etc., depending on the communication protocol between the sensor suite and the management platform. These data packets may be sent periodically or on demand, depending on the configuration and mode of operation of the sensor group and the energy management platform. The sensor group comprises a plurality of sensors, and can comprise a temperature sensor, a current-voltage sensor and the like.
Next, the management platform will perform cleaning, sorting and normalizing processes on the operational parameter data packets. Data cleansing may include outliers removal, missing value padding, noise cancellation, etc., to ensure accuracy and integrity of the data. Data classification is the grouping of data according to certain criteria, such as type, equipment, etc., to facilitate subsequent analysis and processing. The normalization process is to convert different types or ranges of data into a unified numerical value or proportional relationship to facilitate subsequent comparison and analysis.
S130, calculating to obtain output electric quantity according to the current temperature and the residual electric quantity.
Specifically, after the management platform obtains the operation parameters of the first energy storage device, the management platform can calculate the output electric quantity according to the current temperature and the residual electric quantity in the operation parameters. The specific calculation mode is that the current temperature and the residual electric quantity are taken as independent variables, and the output electric quantity is taken as the dependent variable. Because the temperature will have an effect on the output power of the energy storage device, the remaining power and the output power are different.
In one possible implementation, the output power is calculated according to the current temperature and the residual power, specifically by the following formula:
;
Wherein, P is the output electric quantity, P 0 is the residual electric quantity, T i is the i-th temperature value, P i is the output electric quantity corresponding to the i-th temperature value, T 0 is the reference temperature, and T is the current temperature.
Specifically, the above-mentioned process is a way of calculating the output power according to the embodiment of the present application. The reference temperature is a temperature value preset by a manager of the management platform for reducing the influence of the temperature on the output power, so as to reach the ideal output power of the energy storage device, for example, 25 ℃. In order to measure the specific influence percentage of temperature on the output electric quantity, the formula introduces the relation among different output electric quantities corresponding to different temperature values for a plurality of times, so that the power distribution can be continuously optimized, and the efficiency and the stability of the whole combined energy storage system are improved. The formula incorporates temperature parameters and by using a comparison of the reference temperature and the current temperature, the change in performance of the energy storage device can be better understood or predicted. Such a comparison may help the devices maintain a stable power output under a variety of different temperature conditions, which helps ensure a reasonable distribution of power among the energy storage devices, thereby preventing any device overload or under-charging. Meanwhile, the system fault prevention device is also beneficial to preventing system faults and improving the reliability and usability of the system. By accurately predicting and controlling the power output, such a formula helps to improve the efficiency of energy use, thereby reducing energy waste.
And S140, if the output electric quantity is smaller than the electric quantity, sending a power supply instruction to the second energy storage device so as to control the second energy storage device to supply power to the terminal device, wherein the second energy storage device is any energy storage device except the first energy storage device in the plurality of energy storage devices.
Specifically, when the output electric quantity is smaller than the power consumption, that is, the first energy storage device corresponding to the current terminal device cannot meet the power demand, the management platform sends a power supply instruction to the second energy storage device, so that the second energy storage device is controlled to supply power to the terminal device. The power instruction may include, among other things, a target device, i.e., the instruction targets a second energy storage device. The power command typically includes operations to start, stop, or regulate the supply of power. The amount of power supplied or the target power level may also be included in the instruction so that the second energy storage device knows how much power needs to be provided to the terminal device. The duration of the power supply, i.e. how long the second energy storage device needs to provide the specified power supply, may also be included in the instructions. An indication of power supply priority may be included in the instruction, meaning that when there are multiple energy storage devices, some devices may need to be powered more preferentially than others.
For example, assume a joint energy storage system for home energy storage, including solar panels, batteries, and supercapacitors as energy storage devices. When the amount of electricity of the solar panel is insufficient to meet the power demand of the household, the management platform can send a power supply instruction to the super capacitor to instruct the super capacitor to supply power to the household load. The power command may include instructing the supercapacitor to supply 100 watts of power for a duration of two hours and with a high priority.
In one possible implementation, before sending the power supply instruction to the second energy storage device, the method further comprises the steps of judging the running state of the second energy storage device, wherein the running state comprises an idle state, a charging state and a discharging state, and determining that the second energy storage device is a power supply device of the terminal device if the second energy storage device is in the idle state.
Specifically, before sending a power supply instruction to the second energy storage device, the management platform further judges an operation state of the second energy storage device, and when confirming that the second energy storage device is in an idle state, determines that the second energy storage device is a power supply device of the terminal device, that is, the second energy storage device defaults to supply power to the terminal device preferentially. Wherein the idle state refers to neither being charged nor being discharged outwards, i.e. the amount of power of the second energy storage device is unchanged. For example, assume a joint energy storage system is a home energy system that includes one solar panel, a battery, and a supercapacitor as energy storage devices. If the solar panel is low in power and the battery is discharging to power the load in the home, the management platform may determine that the supercapacitor is in an idle state. The management platform may then determine the supercapacitor as the device that supplies power to the terminal device and send a power supply command to the supercapacitor to supplement the power supply.
In one possible implementation, if the second energy storage device is in a charging state, a charging and discharging time interval of the second energy storage device is obtained, and a time for sending a power supply instruction to the second energy storage device is determined according to the charging and discharging time interval.
In particular, the charge-discharge time interval refers to the time required for the energy storage device to charge from the beginning to the time that it can discharge. This time interval depends on the type of device and the current state. For example, the battery may take 30 minutes to 1 hour to charge from a fully discharged state to a state where power can be supplied, while the supercapacitor may complete charging and begin discharging in a shorter time, such as 1 minute to 10 minutes. The management platform can determine when the power supply command is most suitable by knowing the charge-discharge time interval of the second energy storage device. For example, if the charging and discharging time interval of the second energy storage device is 30 minutes, the energy management platform may send a power supply instruction to the second energy storage device when 30 minutes after it completes the last charging. The power supply can be more reasonably scheduled and distributed by determining the sending time of the power supply instruction according to the charging and discharging time interval, so that the charging and discharging processes of the energy storage devices are matched with the power requirements. By monitoring and adjusting the charge and discharge time intervals of each energy storage device, energy sources can be managed and used more effectively, and the use efficiency of the energy sources is improved. By monitoring the charge and discharge states of the second energy storage equipment in real time, the problems in the charge and discharge processes can be found in time, and corresponding preventive maintenance measures are taken to ensure the stable operation of the equipment.
In one possible implementation, the combined energy storage system further comprises a charging device, and after sending the power supply instruction to the second energy storage device if the output power is smaller than the power consumption, the method further comprises sending a charging instruction to the charging device to control the charging device to charge the first energy storage device.
In particular, in addition to the energy storage devices referred to above, such as batteries and supercapacitors, the combined energy storage system also includes a charging device, such as a power adapter or solar charging panel. When the output power is smaller than the power consumption, it means that the power of the first energy storage device is insufficient, and the first energy storage device needs to be charged for power supply again. Thus, the management platform may send a charging instruction to the charging device. For example, assume that the combined energy storage system is a home energy system comprising a solar charging panel, a battery and a supercapacitor, while also having a power adapter as a charging device. When the battery is not sufficiently charged to meet the power demand of the household and the super capacitor is already in an idle state, the management platform can send a charging instruction to the power adapter or the solar charging panel to start charging the battery. Meanwhile, the energy management platform can also send a power supply instruction to the super capacitor so as to control the super capacitor to supply power to household loads, and the power requirements of families are met. Therefore, the energy management platform realizes flexible and efficient management of power supply and demand and energy distribution by coordinating the work of the plurality of energy storage devices and the charging devices.
In one possible implementation manner, if the output power is greater than or equal to the power consumption, a power supply instruction is sent to the first energy storage device to control the first energy storage device to supply power to the terminal device.
In particular, the output power is greater than or equal to the power consumption, which means that the power of the first energy storage device is sufficient to meet the power requirements of the terminal device. The management platform then sends a power command to the first energy storage device. For example, assume that the combined energy storage system is a home energy system comprising a battery and a supercapacitor, and the terminal device is a home appliance. When the electric quantity of the solar panel is enough to meet the power demand of a household, the management platform can send a power supply instruction to the battery so that the battery starts to supply power to the household appliance. Therefore, the energy management platform realizes the optimized power supply strategy under the condition of balanced or excessive power supply and demand by adjusting the power supply sequence and the priority of different energy storage devices, and is convenient for reasonably distributing the power energy.
The application further provides an energy distribution device for the combined energy storage system, and referring to fig. 2, fig. 2 is a schematic block diagram of the energy distribution device for the combined energy storage system according to an embodiment of the application. The energy distribution device is a management platform, the management platform comprises an acquisition module 21 and a processing module 22, wherein the acquisition module 21 is used for receiving a load demand sent by a terminal device, the load demand comprises electricity consumption, the load demand is used for representing the demand of the electricity consumption required by the terminal device, the acquisition module 21 is also used for acquiring operation parameters of first energy storage devices, the operation parameters comprise current temperature and residual electricity, the combined energy storage system comprises a plurality of energy storage devices, the first energy storage devices are energy storage devices for supplying electricity to the terminal device, the processing module 22 is used for calculating to obtain output electricity according to the current temperature and the residual electricity, and the processing module 22 is also used for sending a power supply instruction to second energy storage devices to control the second energy storage devices to supply electricity to the terminal device if the output electricity is smaller than the electricity consumption, and the second energy storage devices are any energy storage devices except the first energy storage devices.
In one possible implementation, the output power is calculated according to the current temperature and the residual power, specifically by the following formula:
;
Wherein, P is the output electric quantity, P 0 is the residual electric quantity, T i is the i-th temperature value, P i is the output electric quantity corresponding to the i-th temperature value, T 0 is the reference temperature, and T is the current temperature.
In one possible implementation, the acquiring module 21 acquires the operation parameters of the first energy storage device, and specifically includes the acquiring module 21 receiving an operation parameter data packet sent by a sensor group, where the sensor group is used to measure the operation parameter data of the first energy storage device, and the processing module 22 preprocessing the operation parameter data packet to obtain the operation parameters of the first energy storage device, where the preprocessing includes data cleaning, data classification and normalization.
In one possible implementation, before the processing module 22 sends the power supply instruction to the second energy storage device, the method further includes that the processing module 22 determines an operation state of the second energy storage device, where the operation state includes an idle state, a charging state, and a discharging state, and if the second energy storage device is in the idle state, the processing module 22 determines that the second energy storage device is a power supply device of the terminal device.
In one possible implementation, if the second energy storage device is in a charging state, the acquiring module 21 acquires a charging and discharging time interval of the second energy storage device, and the processing module 22 determines a time for sending a power supply instruction to the second energy storage device according to the charging and discharging time interval.
In one possible implementation, the combined energy storage system further comprises a charging device, and after the processing module 22 sends the power supply instruction to the second energy storage device if the output power is smaller than the power consumption, the processing module 22 sends the charging instruction to the charging device to control the charging device to charge the first energy storage device.
