The hydropower, wind power and photovoltaic power generation in the integrated water, wind, photovoltaic and energy storage project are all clean energy, which only produces a small amount of greenhouse gas emissions such as carbon dioxide, and has less pollution to the environment. However, in order to analyze the optimization degree of the integrated water, wind, photovoltaic and energy storage project, it is necessary to specifically analyze the emission reduction effect of the integrated water, wind, photovoltaic and energy storage project.

[0003] In the relevant technology, a series of standardized processes and methods are used to help the design, review, calculation and monitoring of greenhouse gas emission reductions of integrated water, wind, solar and storage projects. When monitoring greenhouse gas emission reductions, greenhouse gas emission reductions are generated by setting baseline scenarios for different scenarios. However, this method is only applicable to specific scenarios such as afforestation, solar thermal, offshore wind power and mangroves, and has a narrow scope of application. In addition, due to the intermittent and volatile characteristics of wind power and photovoltaics, it is difficult to effectively predict the output, and the matching degree between the power supply and the load end is not good, resulting in a certain degree of wind, solar and water abandonment, which leads to the emission reduction effect being not accurate enough.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] At present, in the field of integrated water, wind, solar and storage technology, wind power and photovoltaics are intermittent and volatile, making it difficult to effectively predict output, affecting the stable supply of the power system. In addition, due to the different regional characteristics of different types of power resources, the matching degree between the power supply end and the load end is poor, resulting in a certain degree of wind, solar and water abandonment. From the perspective of greenhouse gas emission reduction, this situation makes it impossible for renewable energy to replace traditional fossil energy as expected, thereby weakening the emission reduction effect of renewable energy.

[0024] The embodiment of the present invention provides a method for determining emission reduction, which introduces an adjustment factor to improve the accuracy of measuring emission reduction.

[0025] According to an embodiment of the present invention, an embodiment of a method for determining an emission reduction amount is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] In this embodiment, a method for determining an emission reduction amount is provided, which can be used in a computer device. Figure 1 is a flow chart of a method for determining emission reduction according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0027] Step S101, obtain the abandoned solar and wind power information corresponding to the first integrated water, wind, solar and storage project, generate the hydropower output regulation result of the hydropower station reservoir area and the inflow and outflow regulation result of the hydropower station reservoir area according to the abandoned solar and wind power information, update the first integrated water, wind, solar and storage project to the second integrated water, wind, solar and storage project according to the hydropower output regulation result and the inflow and outflow regulation result, and obtain the grid-connected power increment corresponding to the second integrated water, wind, solar and storage project.

[0028] Among them, the first integrated water, wind, solar and storage project combines solar energy, water energy, wind energy and energy storage systems, and operates them in a coordinated manner through an intelligent control system. "Water" represents hydropower, including conventional hydropower stations and pumped-storage power stations; "wind" refers to wind power generation; "light" represents solar power generation, mainly photovoltaic power generation and solar thermal power generation; "storage" refers to the energy storage system, including battery energy storage, pumped storage and other forms.

[0029] In some optional implementations, the abandoned solar and wind power information is used to characterize the abandoned solar and wind power volume corresponding to the first hydro-wind-solar-storage integrated project. When the abandoned solar and wind power volume is large, it is necessary to adjust the hydropower output of the hydropower station reservoir area and the inflow and outflow flow of the hydropower station reservoir area, so as to reduce the abandoned solar and wind power volume and improve the energy utilization rate. The hydropower output adjustment result is the hydropower output obtained after adjusting the hydropower output of the hydropower station reservoir area, and the inflow and outflow flow adjustment result is the inflow and outflow flow obtained after adjusting the inflow and outflow flow of the hydropower station reservoir area.

[0030] For example, when wind and solar power output is insufficient, the output of hydropower is increased to make up for the shortfall in wind and solar power output. When wind and solar power output is excessive, the output of hydropower is reduced to make full use of the wind and solar power output, thereby reducing wind and solar power abandonment. The inflow and outflow flows are adjusted according to hydrological forecasts to ensure that the reservoir has sufficient regulation capacity during critical periods.

[0031] In some optional embodiments, for the water-wind-solar-storage system corresponding to the first water-wind-solar-storage integrated project, the water-wind-solar-storage system can be constrained by the maximum output, total power generation, minimum wind and solar curtailment objective function and water-wind-solar-storage system constraints.

[0036] In some optional implementations, the formula for determining the total power generation is:

[0037]

[0038] Among them, E total is the total power generation, T is the total time of the whole year, P net,t is the net output power of the water-wind-solar-storage system in time period t, Δt is the time interval, the total time for a whole year can be 8760 hours, and the time interval can be 1 hour.

[0039] Among them, the formula for calculating the net output power of the water-wind-solar-storage system in time period t is:

[0040] P net,t =P max,t -P loss,t ,

[0041] Among them, P net,t is the net output power of the hydro-wind-solar-storage system in time period t, P max,t is the maximum output of the water-wind-solar-storage system, P loss,t The power loss includes transmission loss and equipment self-consumption.

[0042] In some optional implementations, the relationship of the minimum wind and solar power abandonment objective function is:

[0043] MIN(E dis )=E dis,wind +E dis,solar ,

[0044] Among them, MIN represents the minimum value, E dis Indicates the total amount of power wasted, E dis,wind Indicates the amount of wind power abandoned, E dis,solar Indicates the amount of abandoned photovoltaic power.

[0045] The formula for determining the amount of abandoned wind power is:

[0046]

[0047] Among them, E dis,wind is the abandoned wind power, P wind,max,t is the maximum wind power output at time t, P wind,t is the actual wind power output at time t, and T is the total time of the whole year.

[0048] The formula for determining the amount of abandoned wind power is:

[0049]

[0050] Among them, E dis,solar is the abandoned wind power, P solar,max,t is the maximum photovoltaic output at time t, P solar,t is the actual photovoltaic output at time t.

[0051] Therefore, the relationship between the minimum wind and solar curtailment objective function can also be expressed as:

[0052]

[0053] Among them, MIN represents the minimum value, E dis Indicates the total amount of power wasted, P solar,max,tis the maximum photovoltaic output at time t, P solar,t is the actual photovoltaic output at time t, P wind,max,t is the maximum wind power output at time t, P wind,t is the actual wind power output at time t, and T is the total time of the whole year.

[0054] In some optional embodiments, the constraints of the water, wind, solar and storage systems ensure the safety and stability of the water, wind, solar and storage systems, including transmission channel constraints, water balance constraints, hydropower station output constraints, wind power output constraints, photovoltaic output constraints, downstream flow constraints and cascade reservoir energy storage change constraints.

[0066] Among them, Pwind,t represents the output of the wind power station in time period t, P wind,min,t is the lower limit of the wind power station output at time t, P wind,max,t is the upper limit of the wind power station output at time t.

[0067] The photovoltaic output constraint is:

[0076] In some optional embodiments, the incremental grid-connected power corresponding to the second integrated water, wind, solar and storage project is obtained, including: when the operating time of the power station corresponding to the second integrated water, wind, solar and storage project exceeds a preset time period, the grid-connected power of the power station operating independently is obtained according to the difference between the historical average annual grid-connected power and the standard deviation of the historical average annual grid-connected power, the historical average annual grid-connected power is the historical average annual grid-connected power of the power station corresponding to the start of the second integrated water, wind, solar and storage project, and the standard deviation of the historical average annual grid-connected power is the standard deviation of the historical average annual grid-connected power of the power station corresponding to the start of the second integrated water, wind, solar and storage project; the incremental grid-connected power is determined according to the difference between the total grid-connected power and the grid-connected power of the power station operating independently.

[0077] Among them, the total grid-connected power generation can be obtained from a preset model or a monitoring value, that is, the actual grid-connected power generation generated by the joint operation of the power station obtained by collecting the preset model. Among them, the preset model is the power station simulation model corresponding to the second hydro-wind-solar-storage integrated project.

[0078] Among them, the preset time period can be set according to the actual situation. The preset time period can be 3 years.
