光伏微电网的多主体合作运营模式及效益分配

Multi-Subject Cooperative Operation Model and Profit Allocation of PV-Based Microgrid

新电改方案允许拥有分布式电源的用户或微电网系统参与电力交易,有利于微电网经济效益的提高。该研究针对由多方经济主体构成的微电网,包括光伏运营商、储能运营商和用户等,分析了电力市场环境下光伏微电网内各主体的市场交易模式,分析形成联盟的动力,提出各经济主体之间合作博弈的模型。光伏微电网以最大化联盟收益为目标采用分时调度模型,对各主体的运行状态进行实时决策,并采用Shapley值法根据各个主体的贡献度对收益进行了分配。可见,合作模式下光伏运营商、储能运营商和用户均提高了经济效益,各方的效益相互间达到平衡,计算复杂度低,有利于促进光伏微电网规模化发展。

The new electric power reform scheme allows the users of distributed generation or microgrid systems to participate in electricity trade,which is beneficial to the improvement of economical benefits of microgrids.Generally,microgrid is composed of several economic entities,including photovoltaic operators,storage operators,and users and so on.Based on the analysis on the impetus of operation consortia,market transaction mode and their cooperative game model among the economic entities of microgrids are proposed.The time-sharing scheduling model of the PV-based microgrid decides the operation status of entities to maximize the benefits of the whole alliance,and the revenue of each member in the alliance is allocated by the Shapley Value method.As can be seen,the revenue of photovoltaic operators,storage operators and users are increased in cooperation mode with the increase of the considerable revenue of the alliance,and achieve the parties mutual balance.Besides,the computational complexity is relatively low,which contributes to the large-scale development of the PV-based microgrid.
