detailed description

In order to further illustrate the carbon dioxide emission monitoring method and monitoring device based on the household ubiquitous energy network provided by the embodiments of the present invention, the detailed description will be described below with reference to the accompanying drawings.

Referring to Fig. 1, the carbon dioxide emission monitoring method based on the household ubiquitous energy network provided by the embodiment of the present invention includes the following steps:

Step 101, the collection module separately collects the equipment information of the household production equipment, the equipment information of the city energy supply equipment, and the household energy consumption data; Provided energy consumption. Specifically, the acquisition module includes sensors, and the acquisition module collects the equipment information of household production equipment and urban energy supply equipment through sensors, and the acquisition module also collects household energy consumption data; Types of energy consumption, various types of energy include: water energy, electric energy, thermal energy and natural gas energy, etc., and various types of energy can be provided by household energy production equipment and/or urban energy supply equipment; And due to different energy supply methods, the corresponding carbon dioxide emissions are different. For example, urban power supply mainly comes from hydropower and thermal power generation, while the electric energy provided by the universal machine is mainly generated by natural gas combustion; therefore, when the same energy When it is provided by both household energy production equipment and urban energy supply equipment, the acquisition module needs to collect the corresponding household energy consumption in the two cases (the energy provided by household energy production equipment and the household energy consumption provided by urban energy supply equipment). energy consumption).

Step 102, the processing module obtains the carbon dioxide emissions of the household ubiquitous energy network according to the equipment information of the household energy production equipment, the equipment information of the city energy supply equipment, the household energy consumption data, and the carbon dioxide emission coefficient corresponding to the household energy consumption data; more detailed To put it bluntly, the equipment information of household production equipment, urban energy supply equipment and household energy consumption data collected by the collection module can be sent to the processing module through the gateway. , and the carbon dioxide emission coefficients corresponding to various types of energy, combined with the equipment information of household production equipment or urban energy supply equipment, the corresponding carbon dioxide emissions when the household ubiquitous energy network consumes different types of energy are obtained; When the family consumes multiple types of energy, the processing module can also add the corresponding carbon dioxide emissions when the home ubiquitous energy grid consumes different types of energy to obtain the total carbon dioxide emissions of the home ubiquitous energy grid.

In the carbon dioxide emission monitoring method based on the home ubiquitous energy network provided by the embodiment of the present invention, the equipment information of the household production equipment, the equipment information of the city energy supply equipment, and the household energy consumption data are collected through the collection module; then the processing module can According to the collected equipment information of household production equipment, equipment information of urban energy supply equipment, household energy consumption data, and the carbon dioxide emission coefficient corresponding to the household energy consumption data, the carbon dioxide emissions in the household ubiquitous energy network are obtained, so that it is very easy Well, the monitoring of carbon dioxide emissions of the household ubiquitous energy network has been realized.

It should be noted that the carbon dioxide emission coefficient refers to the amount of carbon emissions produced per unit of energy during the combustion or use of each energy. In practical applications, according to the regulations of the Intergovernmental Panel on Climate Change, it can be considered that the carbon dioxide emission coefficient of a certain energy source is fixed, for example: the carbon dioxide emission of household natural gas (kg) = natural gas use degree × 0.19 (0.19 is Carbon dioxide emission coefficient of natural gas energy), carbon dioxide emission of domestic tap water (kg) = degree of tap water usage × 0.91 (0.91 is the carbon dioxide emission coefficient of water energy). According to the relevant regulations of the Intergovernmental Panel on Climate Change, the carbon dioxide emission coefficients of various forms of energy are given, and these carbon dioxide emission coefficients can be used directly, but there are some forms of energy, such as thermal energy, which the Intergovernmental Panel on Climate Change does not Given its carbon dioxide emission coefficient, the carbon dioxide emission monitoring method based on the household ubiquitous energy network provided by the embodiment of the present invention can make a corresponding conversion of this type of energy into energy with a known carbon dioxide emission coefficient and carry out corresponding calculate.

There are many types of household production equipment mentioned above, such as: universal energy generator, photovoltaic and supplementary combustion boiler, etc. Among them, both the universal energy generator and photovoltaic can be used to generate heat and electricity, and the supplementary combustion boiler is used to generate heat energy. Taking the home ubiquitous energy network including ubiquitous energy machines and photovoltaics as an example, the specific calculation process of the carbon dioxide emission of the home ubiquitous energy network will be described in detail below.

When the household production equipment is a universal energy machine, in the above step 101, the equipment information of the household energy production equipment collected by the acquisition module is the power generation efficiency of the internal combustion engine of the universal energy machine, and the acquisition module simultaneously collects the amount of energy (electricity) provided by the universal energy machine. and/or heat), and then the acquisition module sends the collected power generation efficiency of the internal combustion engine and the amount of energy provided by the universal energy machine to the processing module; in the above step 102, the processing module provides The amount of energy, and the carbon dioxide emission coefficient of the universal energy machine corresponding to different types of energy, obtain the carbon dioxide emission of the universal energy machine in the home universal energy network.

In practical applications, the universal energy machine will provide thermal energy and/or electric energy according to the energy demand of the family, and corresponding to different energy supply situations, the calculation method of the corresponding carbon dioxide emission of the universal energy machine is different, and the universal energy machine is given below. The calculation method of the carbon dioxide emission corresponding to the specific energy supply of the machine.

When the universal energy machine generates heat energy, in the above step 101, the acquisition module collects the heat provided by the universal energy machine, and sends the data corresponding to the collected heat to the processing module; in the above step 102, the processing module The heat provided by the machine and the carbon dioxide emission coefficient of the universal energy machine are used to obtain the carbon dioxide emission when the universal energy machine generates heat energy in the home universal energy network.

Specifically, the heat energy generated by the universal energy machine can be converted into natural gas combustion, that is, according to the heat energy generated by the universal energy machine and the conversion efficiency of the internal combustion engine inside the universal energy machine, the amount of natural gas that needs to be consumed to generate this part of heat is calculated, and then calculated The carbon dioxide emission corresponding to the combustion of natural gas is the carbon dioxide emission when the universal energy machine generates heat energy. Since the combustion calorific value of natural gas per cubic meter is 8000 kcal to 8500 kcal, and 1 kcal = 4.1868 kJ, it can be obtained that the combustion calorific value of natural gas per cubic meter is 33494.4 kJ to 35587.8 kJ, thus producing 1 kJ The heat required to burn at least cubic meters of natural gas. According to the above analysis of the relationship between the heat energy generated by the universal machine and the combustion of natural gas, it can be obtained that the amount of natural gas that the universal machine needs to consume to generate E _hue kilojoules of heat is: cubic meter. Therefore, the carbon dioxide emission M _hue when the ubiquitous machine in the household ubiquitous energy network produces E _hue kilojoule heat energy is:

${\mathrm{<span\; class="notranslate">\; m</span>}}_{\mathrm{<span\; class="notranslate">\; h</span>}\mathrm{<span\; class="notranslate">\; u</span>}\mathrm{<span\; class="notranslate">\; e</span>}}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; E.</span>}}_{\mathrm{<span\; class="notranslate">\; h</span>}\mathrm{<span\; class="notranslate">\; u</span>}\mathrm{<span\; class="notranslate">\; e</span>}}}{\mathrm{<span\; class="notranslate">\; 35587.8</span>}}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; C</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; )</span>$

Among them, E _hue is the heat provided by the universal machine, is the carbon dioxide emission coefficient corresponding to the heat generated by the universal energy machine, and C _c is the carbon dioxide emission coefficient of natural gas energy.

When the universal energy machine generates electric energy, in the above step 101, the acquisition module collects the power generation efficiency of the internal combustion engine of the universal energy machine and the electricity provided by the universal energy machine, and sends the data corresponding to the collected electricity to the processing module; in the above steps In 102, the processing module obtains the carbon dioxide emission when the ubiquitous machine generates electric energy in the household ubiquitous energy network according to the electricity provided by the ubiquitous machine and the carbon dioxide emission coefficient of the ubiquitous machine.

In more detail, the efficiency of generating electric energy of the universal energy machine is related to the power generation efficiency of the internal combustion engine used, that is, the efficiency of generating electric energy of the universal energy machine will vary with the power generation efficiency of the internal combustion engine, and the power generation efficiency η of the internal combustion engine of the universal energy machine is generally At 35%-40%, since 1 kWh is equal to kcal, combined with the power generation efficiency η of the internal combustion engine, it can be obtained that the heat required by the universal energy machine to generate 1 degree of electricity is Kcal, according to the relationship between the heat generated by the universal machine and the natural gas it consumes, it can be obtained that the maximum amount of natural gas consumed by the universal machine to generate 1 kilowatt-hour of electricity is about cubic meter. According to the relationship between the electric energy generated by the above-mentioned universal energy machine and the burning of natural gas, the carbon dioxide emission M _eue when the universal energy machine in the household universal energy network generates electric energy can be obtained as:

${\mathrm{<span\; class="notranslate">\; m</span>}}_{\mathrm{<span\; class="notranslate">\; e</span>}\mathrm{<span\; class="notranslate">\; u</span>}\mathrm{<span\; class="notranslate">\; e</span>}}<span\; class="notranslate">\; =</span>{\mathrm{<span\; class="notranslate">\; E.</span>}}_{\mathrm{<span\; class="notranslate">\; e</span>}\mathrm{<span\; class="notranslate">\; u</span>}\mathrm{<span\; class="notranslate">\; e</span>}}<span\; class="notranslate">\; \&times;</span>\frac{\mathrm{<span\; class="notranslate">\; 3600</span>}}{\mathrm{<span\; class="notranslate">\; 4.187</span>}<span\; class="notranslate">\; \&times;</span>\mathrm{<span\; class="notranslate">\; 8000</span>}<span\; class="notranslate">\; \&times;</span>\mathrm{<span\; class="notranslate">\; \&eta;</span>}}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; C</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; )</span>$

Among them, E _eue is the electric power provided by the universal energy machine, η is the power generation efficiency of the internal combustion engine of the universal energy machine, is the carbon dioxide emission coefficient corresponding to the power generation of the universal energy generator, and C _c is the carbon dioxide emission coefficient of natural gas energy.

When the home production equipment is photovoltaic, photovoltaic can generate both electric energy and thermal energy in the presence of light, but it has almost no carbon dioxide emissions in the process of generating electric energy and thermal energy, so when generating electric energy and thermal energy through photovoltaic CO2 emissions are negligible.

Since the electric energy and heat energy generated by household energy production equipment are relatively limited, it may happen that the electricity and heat energy provided by household energy production equipment cannot meet the needs of households, and when this happens, the energy will be supplied by the city equipment to provide the energy needed by the home.

When the household ubiquitous energy network uses urban energy supply equipment, in the above step 101, the collection module collects the boiler efficiency, heat transfer pipe efficiency, and heat network heat exchanger efficiency of the urban energy supply equipment, and the collection module simultaneously collects the household pair by city The energy consumption provided by the energy supply equipment, and then the acquisition module sends the collected boiler efficiency, heat transfer pipe efficiency, heat network heat exchanger efficiency, and household consumption of energy provided by the urban energy supply equipment to the processing module ; In the above-mentioned step 102, the processing module is based on the received boiler efficiency, heat transfer pipe efficiency, heat network heat exchanger efficiency, household consumption of energy provided by the urban energy supply equipment, and the energy provided by the urban energy supply equipment. The carbon dioxide emission coefficients corresponding to different types of energy sources are used to obtain the carbon dioxide emissions of urban energy supply equipment used by the household ubiquitous energy network. It should be noted that the different types of energy provided by urban energy supply equipment include: heat energy, electric energy, water energy and natural gas energy, and different types of energy have corresponding carbon dioxide emission factors.

According to the actual needs of the family, the urban energy supply equipment will provide the corresponding type of energy for the household. Corresponding to different energy supply situations, the calculation method of the carbon dioxide emission of the household ubiquitous energy network using the urban energy supply equipment is different. The following gives the urban energy supply Under the specific energy supply conditions of energy equipment, the calculation method of carbon dioxide emissions corresponding to the household ubiquitous energy network.

When the urban energy supply equipment provides heat energy, in the above step 101, the collection module collects the boiler efficiency, heat transfer pipe efficiency, and heat network heat exchanger efficiency of the urban energy supply equipment, and the collection module simultaneously collects the household’s The consumption of heat energy provided; in step 102, the processing module is based on the boiler efficiency of the urban energy supply equipment, the efficiency of the heat transfer pipe, the efficiency of the heat exchanger of the heat network, the consumption of the heat energy provided by the urban energy supply equipment by the household, and The carbon dioxide emission coefficient of standard coal is used to obtain the carbon dioxide emission when the household ubiquitous energy grid uses urban heating.

Specifically, the thermal energy provided by urban energy supply equipment can be converted into standard coal combustion, that is, the amount of standard coal consumed by urban heating equipment to provide a certain amount of thermal energy can be calculated first, and then the corresponding carbon dioxide emissions of standard coal combustion can be calculated With reference to the existing research results, the relationship between the standard coal B _gr (unit is kilogram) and household consumption of heat energy provided by urban energy supply equipment E _hci (unit is GJ) can be obtained as follows:

${\mathrm{<span\; class="notranslate">\; B</span>}}_{\mathrm{<span\; class="notranslate">\; g</span>}\mathrm{<span\; class="notranslate">\; r</span>}}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; E.</span>}}_{\mathrm{<span\; class="notranslate">\; h</span>}\mathrm{<span\; class="notranslate">\; c</span>}\mathrm{<span\; class="notranslate">\; i</span>}}}{\mathrm{<span\; class="notranslate">\; 29308</span>}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; \&eta;</span>}}_{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; \&eta;</span>}}_{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; \&eta;</span>}}_{\mathrm{<span\; class="notranslate">\; 3</span>}}}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 3</span>}<span\; class="notranslate">\; )</span>$

Wherein, η ₁ is the boiler efficiency, η ₂ is the pipeline efficiency, and η ₃ is the heat exchanger efficiency of the heat network.

According to the formula (3), the carbon dioxide emission M _hci when the household ubiquitous energy network uses urban heating can be obtained as:

${\mathrm{<span\; class="notranslate">\; m</span>}}_{\mathrm{<span\; class="notranslate">\; h</span>}\mathrm{<span\; class="notranslate">\; c</span>}\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; E.</span>}}_{\mathrm{<span\; class="notranslate">\; h</span>}\mathrm{<span\; class="notranslate">\; c</span>}\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; C</span>}}_{\mathrm{<span\; class="notranslate">\; m</span>}}}{\mathrm{<span\; class="notranslate">\; 29308</span>}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; \&eta;</span>}}_{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; \&eta;</span>}}_{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; \&eta;</span>}}_{\mathrm{<span\; class="notranslate">\; 3</span>}}}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 4</span>}<span\; class="notranslate">\; )</span>$

Among them, C _m is the carbon dioxide emission coefficient of standard coal.

When the urban energy supply equipment provides electric energy, in the above-mentioned step 101, the collection module collects the household consumption of electric energy provided by the urban energy supply equipment, and sends it to the processing module; in the above-mentioned step 102, the processing module receives According to the household consumption of electric energy provided by urban energy supply equipment, and the carbon dioxide emission coefficient of municipal power, the carbon dioxide emission when the household ubiquitous energy network uses urban power supply is obtained.

In more detail, according to the existing carbon dioxide emission monitoring results of municipal electricity, the carbon dioxide emission _Meci when the household ubiquitous energy network uses urban power supply can be obtained as:

M _eci =E _eci ×C _e (5)

Among them, E _eci is the household consumption of electric energy provided by urban energy supply equipment, and C _e is the carbon dioxide emission coefficient of municipal power.

When the urban energy supply equipment provides water energy, in the above step 101, the collection module collects the household consumption of water energy provided by the urban energy supply equipment, and sends it to the processing module; in the above step 102, the processing module According to the received household consumption of water energy provided by urban energy supply equipment and the carbon dioxide emission coefficient of water energy, the carbon dioxide emission when the household ubiquitous energy network uses water energy is obtained.

Furthermore, the carbon dioxide emission M _w when the household ubiquitous energy network uses water energy is:

M _w =E _w ×C _w (6)

Among them, E _w is the household consumption of water energy provided by urban energy supply equipment, and C _w is the carbon dioxide emission coefficient of water energy.

When the urban energy supply equipment provides natural gas energy, in the above step 101, the collection module collects the household consumption of natural gas energy provided by the urban energy supply equipment, and sends it to the processing module; in the above step 102, the processing module According to the received household consumption of natural gas energy provided by urban energy supply equipment and the carbon dioxide emission coefficient of natural gas energy, the carbon dioxide emission when the household ubiquitous energy network uses natural gas energy is obtained. It is worth noting that the carbon dioxide emission coefficient of natural gas energy involved here is the carbon dioxide emission coefficient corresponding to the direct combustion of natural gas, which is different from the carbon dioxide emission coefficient of natural gas corresponding to the universal energy machine.

Specifically, the carbon dioxide emission _Mc when the household ubiquitous energy network uses natural gas energy is:

M _c =E _c ×C _c (7)

Among them, E _c is the household consumption of natural gas energy provided by urban energy supply equipment, and C _c is the carbon dioxide emission coefficient of natural gas energy.

Based on the above analysis, there are three main sources of heat energy consumed in the household ubiquitous energy network, namely, the heat energy generated by the ubiquitous energy machine burning natural gas, the thermal energy provided by urban energy supply equipment, and photovoltaic heat generation. The process of photovoltaic heat generation has almost no carbon dioxide emissions. , so the carbon emissions caused by heat energy consumption in the household ubiquitous energy network mainly come from the heat production process of the ubiquitous energy machines burning natural gas and urban energy supply equipment.

Thus, the carbon dioxide emission M _h when consuming heat energy in the household ubiquitous energy grid is obtained as:

M _h =M _hue +M _hci (8)

That is, the sum of the carbon dioxide emission M _hue when the ubiquitous energy machine generates heat energy and the carbon dioxide emission M _hci when the household ubiquitous energy network uses urban heating.

The electricity consumed in the household ubiquitous energy network mainly comes from three sources, namely, the electricity generated by the ubiquitous energy machine burning natural gas, the electricity provided by urban energy supply equipment, and photovoltaic power generation. The process of photovoltaic power generation has almost no carbon dioxide emissions. Therefore, household The carbon emissions caused by electricity consumption in the ubiquitous energy grid mainly come from the process of burning natural gas in ubiquitous energy machines and the electricity production process of urban energy supply equipment.

Thus, the carbon dioxide emission Me when consuming electric energy in the household _ubiquitous energy network is obtained as:

M _e =M _eue +M _eci (9)

That is, the sum of the carbon dioxide emission _Meue when the ubiquitous machine generates electric energy and the carbon dioxide emission _Meci when the household ubiquitous energy network uses urban power supply.

To sum up, the total carbon emission M of the household ubiquitous energy network is:

M＝M _h +M _e +M _w +M _c (10)

That is, the total amount of carbon emissions generated when the home ubiquitous energy network uses heat energy, electricity energy, water energy and natural gas energy.

It is worth noting that the parameters involved in formulas (1) to (10) can be measured in units of year, that is, to calculate the annual carbon dioxide emissions, and the corresponding energy consumption used is also the annual consumption.

Please continue to refer to Figure 1, the method for monitoring carbon dioxide emissions based on the household ubiquitous energy network provided by the above embodiment also includes:

Step 103, the control module matches the production capacity and energy consumption of the home ubiquitous energy grid according to the carbon dioxide emissions of the home ubiquitous energy grid; Production and utilization energy matching optimization control indicators (energy saving indicators, environmental protection indicators, economic indicators, and comfort indicators) to achieve the matching of the production capacity and energy consumption of the household ubiquitous energy grid, and the carbon dioxide emissions of the household ubiquitous energy grid obtained in the above step 102 can be As the environmental protection index in the optimal control index. In addition, when actually matching the production capacity and energy consumption of the household ubiquitous energy network, the priority of energy-saving indicators, environmental protection indicators, economic indicators and comfort indicators can be considered. Reduce the comfort index (for example, the air conditioner of the energy-consuming equipment adopts the power-saving mode), so as to ensure the environmental protection index, etc.

According to the above analysis, it is a multi-objective optimization problem for the control module to realize the matching optimization control of household ubiquitous energy network production and utilization. However, there are many processing methods that can be used for the multi-objective optimization problem, such as the linear weighted combination method. This method is based on The importance of each objective is given a corresponding weight, and then each objective is multiplied by its corresponding weight, and then added together to form a unified objective function. In addition, multi-objective optimization problems can be realized through tolerance method and weighted factor decomposition method.

It is worth noting that the above-mentioned control module can obtain the carbon dioxide emission of the household ubiquitous energy network in various ways, and a specific acquisition method is given below, but of course it is not limited to the given method.

In the above step 102, the processing module sends the carbon dioxide emissions of the home ubiquitous energy network to the storage module, and the storage module stores the received carbon dioxide emissions of the home ubiquitous energy network; The carbon dioxide emissions of the home ubiquitous energy network are used in the middle to realize the matching of production and consumption of the home ubiquitous energy network.
