Research On The Method Of Distributed Photovoltaic Resource Allocation Of Incremental Distribution Network Based On Game Theory

In the market environment where the incremental distribution business is gradually liberalized,the incremental distribution network can be invested by social capital or grid companies.The incremental distribution network accounts income independently in the power market competition,and investment planning pays more attention to the profitability of future operations.Incremental power distribution network investing in the construction of distributed photovoltaic can save the power purchase cost and increase the electricity sales income for its later operation.Due to the distributed photovoltaic power generation characteristics and the actual load demand in the power grid,the construction capacity of distributed photovoltaic system in the incremental distribution network is limited.At the same time,distributed photovoltaic has different operation modes of investment entities,and users in the incremental distribution network can use their idle land resources such as walls,roofs,and open fields to construct distributed photovoltaic system.Therefore,the incremental distribution network and users compete with each other for the limited distributed photovoltaic construction resources in the incremental distribution network.When planning the distributed photovoltaic of the incremental distribution network,how to make the optimal distributed photovoltaic allocation scheme according to the investment behavior and cost benefit decision of incremental distribution network operators and users in distributed photovoltaic system construction is a key issue facing the construction of incremental distribution networks.For the above problems,this paper discusses the rational allocation method of distributed photovoltaic construction resources in the incremental distribution network.Firstly,the development of incremental distribution network and its related operation mechanism are analyzed.Based on the summary of the policies related to the incremental distribution network project and photovoltaic power generation,the domestic existing distributed photovoltaic system power generation investment entities and operation modes are analyzed,and the responsibilities and obligations of the owners of the incremental distribution network project are introduced.The operation mechanism of the incremental distribution network is analyzed from the perspective of diversification and integration of operation subjects.Secondly,the economic evaluation model of the investment and operation method of incremental distribution network is established.In view of the distributed photovoltaic system cost and operation problems,the cost-benefit composition of the incremental distribution network under different distributed photovoltaic investment operation modes is analyzed by referring to the research on the existing operation modes.The comprehensive benefit evaluation model of the incremental distribution network based on different operation modes is established,and the comprehensive benefit analysis flow chart of the incremental distribution network with distributed photovoltaic is proposed.On the basis of the actual case analysis,the comprehensive benefits under different modes are evaluated,and the optimal incremental distribution network investment operation mode is selected.Finally,this paper focuses on the research of distributed photovoltaic site resource allocation method in the incremental distribution network.Both the incremental distribution network and users want to build distributed photovoltaic to improve their own economic benefits and compete for limited distributed photovoltaic construction resources in the incremental distribution network.In order to obtain a reasonable distributed photovoltaic construction resource allocation and capacity allocation scheme,a dynamic game model of incremental distribution network and users is established by game theory,and a planning decision-making model of incremental distribution network investment operators and users is constructed respectively,and the game behavior between them is analyzed.Finally,the above model is solved by iterative search method,and an example is analyzed.
