Description

Technical Field

[0001] The present invention relates to a method and system for calculating the additionality of carbon emissions reduction in a power grid dispatching mode, belonging to the technical field of energy environment market management. Background Art

[0002] The power grid connects energy production and consumption and is the network hub for energy transmission and conversion utilization. With the increase in the power generation of renewable energy, the "dual-high" characteristics of a power system with a high proportion of renewable energy and a high proportion of power electronic devices are becoming more and more prominent, posing a serious challenge to the safe and stable operation of the power grid. The electricity demand shows "double-peak" characteristics in winter and summer, and the peak-valley difference is continuously expanding. The intermittency of new energy power generation will make the peak regulation and frequency modulation pressure of the power grid increasingly large. In order to achieve the carbon emissions reduction goal of the power system, the power grid must absorb more and more new energy power generation, that is, adopt a clean energy dispatching mode, which requires the power grid to make greater investments in aspects such as UHV, energy storage, demand-side response, smart grid, and dispatching operation, resulting in an increase in network losses and operating costs. The parameter for the power grid company to quantify the carbon emissions reduction amount brought by the paid cost is the additionality of carbon emissions reduction, but there is currently no corresponding calculation method.

Description of the Drawings

[0032] Figure 1 It is a flow chart of the calculation method for the additionality of carbon emission reduction of the power grid scheduling mode. Specific implementation mode

[0033] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0034] As Figure 1 shown, a method for calculating the additionality of carbon emission reduction in a power grid dispatching mode includes the following steps:

[0035] Step 1, equivalent the power grid;

[0036] Step 2, construct the typical annual operation mode of the power grid according to the seasonal load characteristics and intra-day load characteristics of the power grid;

[0037] Step 3, construct the boundary conditions of the power grid and the simulation parameters matching the typical annual operation mode according to the actual situation of the power grid;

[0038] Step 4, under the minimum network loss dispatching mode, carry out the simulation of the AC optimal power flow operation mode of the power grid according to the equivalent power grid, boundary conditions and simulation parameters, and calculate the baseline carbon emissions; under the clean energy consumption dispatching mode, carry out the simulation of the AC optimal power flow operation mode of the power grid according to the equivalent power grid, boundary conditions and simulation parameters, and calculate the comparative carbon emissions;

[0039] Step 5, calculate the additionality of carbon emission reduction according to the baseline carbon emissions and the comparative carbon emissions.

[0040] The above method respectively carries out the simulation of the AC optimal power flow operation mode of the power grid under the clean energy consumption dispatching and the minimum network loss dispatching mode, calculates the carbon emissions under different dispatching modes, calculates the additionality of carbon emission reduction in the power grid dispatching mode, can help the power grid company quantitatively calculate the carbon emission reduction amount brought by the cost paid, evaluate the contribution made by the power grid company to carbon emission reduction, and encourage the power grid company to actively support the carbon emission reduction of the power system.

[0041] The main body of the above method obtains the carbon emissions through simulation. Therefore, it is necessary to first obtain the simulation basic grid data, that is, equivalent the power grid. Specifically: equivalent the power grid below 220KV according to the physical topology of the power grid, and equivalent the load below 220KV to the 220KV node to form an equivalent power grid of 220KV and above in the power grid.

[0042] Then, according to the seasonal load characteristics and intra-day load characteristics, the typical annual operation mode of the power grid can be constructed. Specifically, it can be as follows:

[0043] Select three typical seasons of spring, summer, and winter according to the load characteristics of the area where the power grid is located. In each day, select three time periods: early morning (0 - 8 o'clock), daytime (8 - 16 o'clock), and night (16 - 24 o'clock); the combination of typical seasons and daily loads forms nine typical operating modes: spring early morning, spring daytime, spring night, summer early morning, summer daytime, summer night, winter early morning, winter daytime, and winter night.

[0044] Among them, the spring early morning operating mode includes the spring load characteristics of the power grid and the spring early morning load characteristics, the spring daytime operating mode includes the spring load characteristics of the power grid and the spring daytime load characteristics, the spring night operating mode includes the spring load characteristics of the power grid and the spring night load characteristics, the summer early morning operating mode includes the summer load characteristics of the power grid and the summer early morning load characteristics, the summer daytime operating mode includes the summer load characteristics of the power grid and the summer daytime load characteristics, the summer night operating mode includes the summer load characteristics of the power grid and the summer night load characteristics, the winter early morning operating mode includes the winter load characteristics of the power grid and the winter early morning load characteristics, the winter daytime operating mode includes the winter load characteristics of the power grid and the winter daytime load characteristics, and the winter night operating mode includes the winter load characteristics of the power grid and the winter night load characteristics.

[0045] According to the historical meteorological information of this province, it is determined that the durations of spring, summer, and winter in each year are a days, b days, and c days respectively. The annual hours of the nine operating modes of spring early morning, spring daytime, spring night, summer early morning, summer daytime, summer night, winter early morning, winter daytime, and winter night are 8*a, 8*a, 8*a, 8*b, 8*b, 8*b, 8*c, 8*c, 8*c respectively, as shown in Table 1 for details.

[0046] Table 1 Annual hours of each operating mode

[0047]

[0048] Then, according to the actual situation of the power grid, the boundary conditions of the power grid and the simulation parameters matching the typical annual operating modes can be constructed; among them,

[0049] The boundary conditions include the limit values of key channel sections and the installed capacities of various types of units. For details, see Tables 2 and 3; among them, the installed capacities of units include the installed capacities of various types of units such as thermal power, hydropower, wind power, photovoltaic power, nuclear power, biomass power generation, and energy storage with years, which can be set according to the power grid planning report;

[0052] Table 3 Installed capacities of various types

[0053]

[0054] The simulation parameters include the power generation of clean energy units, the load factor (the load factor refers to the percentage of the average load to the maximum load within the statistical period (day, month, year)), and the transmission power of tie lines. Specifically, see Tables 4 and 5; among them, the power generation and load factor can be set according to the historical load curve and the meteorological resource conditions such as wind and light in this area.

[0059]

[0060]

[0061] Note: The received power of this power grid is positive, and the sent power is negative, with the unit of MW.

[0062] Under the minimum line loss dispatch mode, according to the equivalent power grid, boundary conditions and simulation parameters, the power grid is simulated for the AC optimal power flow operation mode to calculate the benchmark carbon emissions; under the clean energy consumption dispatch mode, according to the equivalent power grid, boundary conditions and simulation parameters, the power grid is simulated for the AC optimal power flow operation mode to calculate and compare the carbon emissions.

[0063] For nine operation modes, AC optimal power flow calculations need to be carried out. The AC optimal power flow calculation will determine the power output of each unit, the load of each node, the power flow of each line and other power grid data according to the set objective function under the satisfaction of the set constraint conditions. Then, by multiplying the power output of the unit by the number of hours and the carbon emission coefficient, the carbon emissions of the unit under this operation mode can be obtained.

[0064] Among them, in the clean energy consumption dispatch scenario, the AC optimal power flow calculation takes the maximum clean energy consumption as the objective function, as shown in the following formula:

[0065] f = maxQ

[0066] where Q is the clean energy consumption.

[0067] Under the minimum line loss dispatch mode, the AC optimal power flow calculation takes the minimum total line loss of the whole network as the objective function, as shown in the following formula:

[0068] f = maxL

[0069] where L is the total line loss of the whole network.

[0070] Finally, the carbon emission reduction additionality can be calculated based on the baseline carbon emissions and the comparison carbon emissions, that is, calculate the difference between the baseline carbon emissions and the comparison carbon emissions.

[0071] For example, in the minimum network loss dispatch mode, the total carbon emissions of the whole network are 37.8428 million tons of carbon dioxide, that is, the baseline carbon emissions are 37.8428 million tons of carbon dioxide; in the clean consumption dispatch mode, the total carbon emissions of the whole network are 24.9359 million tons of carbon dioxide, and the comparison carbon emissions are 24.9359 million tons of carbon dioxide; then the additional carbon emission reduction of the power grid dispatch is 37.8428 - 24.9359 = 12.9069 million tons of carbon dioxide, which means that for this target power grid under the set simulation parameters and boundary conditions, after the power grid dispatch mode changes from the minimum network loss dispatch mode to the clean energy consumption dispatch mode (that is, from the baseline dispatch mode to the comparison dispatch mode), the whole network reduces carbon dioxide emissions by 12.9069 million tons.

[0072] Based on the same technical solution, the present invention also discloses a system for calculating the additional carbon emission reduction of the power grid dispatch mode, including:
