Multi-agent Cooperative Operation Model and Profit Allocation of PV-based Microgrid

Abstract

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 economic benefits of microgrid. Generally, microgrid is composed of several economic members, including photovoltaic operators, storage operators, 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 members in microgrid are proposed. The time-sharing scheduling model of PV-based microgrid decides the operation status of members 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 alliance, and achieve the parties’ mutual balance. Besides, the computational complexity is relatively low, which contributes to the large-scale development of PV-based microgrid.
