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 obvious dual-peak characteristics of electricity, few local power generation resources, an increasing proportion of new energy, and abundant adjustable load resources. Virtual power plants can aggregate multiple adjustable loads and distributed photovoltaic and other heterogeneous resources through advanced communication and computer technologies, which has great strategic significance in promoting the consumption of new energy, promoting energy transformation, and saving energy and reducing carbon emissions.

[0003] The "Implementation Rules for the Management of Power Auxiliary Services in the East China Region" (hereinafter referred to as the "Rules") clearly stipulate that the grid-connected entities of power auxiliary services in East China include virtual power plants. The "Rules" mention that power auxiliary services in the East China region are divided into basic auxiliary services and paid auxiliary services. Among them, basic auxiliary services are provided by the grid-connected entities as an obligation and no compensation is required; paid peak-shaving in paid auxiliary services includes deep peak-shaving compensation, start-stop peak-shaving compensation for large traditional power generating units, and adjustable load peak-shaving (valley-filling) compensation. In general, 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 bring benefits. At the same time, the carbon market is also developing rapidly. Traditional power generating 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 assessed by the carbon market 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 study. Summary of the invention
