Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of power grid transaction revenue distribution, and in particular relates to a virtual power plant revenue distribution method based on generalized Nash bargaining in an electricity-carbon coupling market. Background Art
[0002] Large cities have a distinct dual-peak electricity demand pattern, limited local power generation resources, a growing share of renewable energy, and abundant adjustable load resources. Virtual power plants, leveraging advanced communications and computing technologies, can aggregate heterogeneous resources such as multiple adjustable loads and distributed photovoltaics. This holds significant strategic significance in promoting the absorption of renewable energy, advancing energy transformation, and bolstering energy conservation and carbon reduction.
[0003] The "Detailed Implementation Rules for the Management of Electric Power Auxiliary Services in the East China Region" (hereinafter referred to as the "Detailed Rules") clearly stipulate that the grid-connected entities of the East China Electric Power Auxiliary Services include virtual power plants. The "Detailed Rules" state that the East China Electric Power Auxiliary Services are divided into basic ancillary services and paid ancillary services. Among them, basic ancillary services are provided by the grid-connected entities as an obligation and do not require compensation; paid peak-shaving in paid ancillary services includes deep peak-shaving compensation, start-up and shutdown peak-shaving compensation for large traditional power generation units, and adjustable load peak-shaving (valley-filling) compensation. Generally speaking, paid peak-shaving in the East China region can be summarized as follows: when electricity is sufficient, the behavior of reducing power generation output and increasing load can both generate benefits. At the same time, the carbon market is also developing rapidly. Traditional power generation units will be issued initial carbon quotas and often need to purchase more carbon quotas from the carbon market to cover carbon emissions. The load may face indirect carbon emission assessments for purchasing electricity from the power grid. Therefore, judging from the development trend of the power environment, virtual power plants may need to participate in power peak regulation and be subject to carbon market assessment in the future. On the one hand, virtual power plants participate in power peak regulation by adjusting loads and abandoning light; on the other hand, virtual power plants can apply for CCER certificates through aggregated distributed photovoltaics to help loads offset a certain amount of carbon emissions. If there are excess carbon quotas, they can be put into the market for trading and profit.
[0004] In the electricity-carbon coupled market, the existing profit distribution method of virtual power plants is difficult to achieve optimal distribution, resulting in weak enthusiasm of various entities to participate in transactions. Therefore, how to design the profit distribution of various participants in virtual power plants needs further research. Summary of the Invention
