The Optimal Operation And Revenue Allocation Of Virtual Power Plant Considering Carbon Trading

In order to cope with the shortage of global fossil energy and environmental problems,distributed energy generation which mainly about renewable energy like wind power and photovoltaic has been developing rapidly in the global scope.Virtual Power Plant(VPP)participates in the electricity market transaction by aggregating many distributed wind power generation and energy storage.On the one hand,the problems of uncontrollable output and random fluctuation are solved when the wind power and photovoltaic distributed generation participates in the market operation alone.On the other hand,participating in power market operation in the form of VPP can promote the consumption of new energy.Besides,carbon trading market is an effective tool to control greenhouse effect.As a new type of market subject,VPP can play its environmental benefits by participating in carbon trading,and the overall benefits of VPP will be improved.Firstly,the concept of VPP is introduced.On this basis,the main body of VPP is modeled.Then,the process of VPP participating in carbon market trading is described,the operation mode of VPP participating in electricity market trading and carbon market trading is analyzed.VPP is mainly composed of micro gas turbine,distributed wind power,distributed photovoltaic and energy storage equipment.Therefore,a two-stage optimal operation model of VPP day ahead bidding is designed.Furthermore,a two-stage optimal operation model of VPP considering carbon emission trading is established.The uncertainty of wind power and photovoltaic output in VPP is modeled,and the risk measure of VPP benefit is introduced.In view of the VPP in electricity market and the carbon emission market coordination operation problem,using conditional value at risk as the risk measure of VPP benefit.By considering wind power and photovoltaic output uncertainty of income risk,and electricity trading and carbon emissions trading,the optimal bidding strategy of VPP in the electricity market is given.In the example,the income of VPP in each market is analyzed.The conclusion that VPP can increase the income of VPP in carbon trading market is obtained.Finally,the method of income distribution based on cooperative game theory is introduced.According to the income of VPP in the electricity market and carbon emission market,the income distribution method of VPP internal members is determined.The contribution degree of each member in VPP is calculated based on the Shapley value of cooperative game theory.The bidding strategies of VPP participating in carbon emission market and electricity market and the revenue allocation of VPP members considering carbon trading are obtained is analyzed through an example.The rationality of the proposed bidding strategy and revenue allocation method is verified.
