用户侧有限理性下基于主从博弈与电热需求响应的综合能源微网优化运行

With the increasing competition of various agents in integrated energy microgrid, it is of the great significance to study the optimal operation of microgrid under multi-stakeholders. First of all, a leader-follower game model is presented, in which the microgrid operators act as leaders, while electric vehicle users act as followers. A microgrid framework considering time-of-use electricity prices, electricity and heat demand response, electric vehicles and the operation mode of microgrid operator, is constructed. Secondly, the "power determined by heat" mode is proposed, which can overcome the shortcomings of the traditional "heat determined by power" mode. At the same time, the profit model of microgrid operator under these two modes is proposed. Then, a user-side limited rationality purchase energy selection model is proposed, which considers electric heating equipment, electric vehicles and demand response. Based on this, a user-side profit model is developed. The proposed model is represented by the leader-follower game framework, and the existence and uniqueness of Stackelberg equilibrium solution are proved. Finally, a simulation test is carried out using genetic algorithm and CPLEX solver. Simulative results show that, the "following-electric-load" mode increases the profits of microgrid operator and users simultaneously under the user-side limited rationality model. At the same time, the proposed purchase energy selection model effectively restrains the market power exercised by microgrid operator.
