Multi-agent profit distribution method considering wind-solar output uncertainty under cooperative game

Abstract

The invention relates to a multi-agent profit distribution method considering wind-solar output uncertainty under a cooperative game, and the method is used for power market transaction in which a virtual power plant containing multiple agents participates, and comprises the following steps: (1) obtaining the clean energy output and load prediction data of each agent; (2) quantifying the uncertainty risk of the clean energy by adopting a conditional risk value theory (CVaR) and a Monte Carlo simulation method to obtain the penalty cost of uncertainty; (3) on the basis of risk quantification, establishing a multi-agent cooperative game model considering risk apportionment, and obtaining cooperative profits and risk apportionment profits; and (4) allocating the total income of the cooperative alliance by adopting Nash negotiation, and taking the risk borne by the alliance participants and the marginal benefit of the cooperative profit as factors for determining allocation factors. Compared with independent transaction of each main body, the risk of system operation can be effectively reduced, the stability is improved, and the benefit of each main body is maximized.

Description

Technical field[0001]The present invention relates to a profit distribution method comprising a multi-body participating in electric power market transaction, especially in power market transactions involved in virtual power plants such as various types of cleaning energy and other virtual power plants, the profit distribution method of internal multi-mainers.Background technique[0002]With the continuous reform of the power market, the market environment on sale is gradually open. Some mains with distributed energy, load, and energy storage began to participate in transactions in the power market. Virtual Power Plant (VPP) is involved in the transaction of the power market to integrate a new transaction in multiple subjects. With the increase in the number of other subjects, the proportion of renewable energy is increasing, the power market has shown many problems; if the market is abandoned seriously; the clean energy competitiveness is weak; the balance is not determined to have a...

Problems solved by technology

The above methods all consider the profit distribution of the cooperation from different angles, but in the process of profit distribution, the impact of the uncertain risks of clean energy borne by the cooperation on the cooperation profit is not considered
