摘　　要：对现阶段光储微电网进行充分了解和研究,使光储微电网经济效益最大化,同时保证光储微电网的稳定性,一种新的基于需求侧响应下的光储微电网运行策略应运而生.根据用户需求改变可转移负荷的使用时间,将可转移负荷的使用进行重新安排,在用电低谷阶段减少配电容量及在用电高峰期释放负荷,在不同时间段定制不同电价,人为调控用电需求量,使得电力资源合理使用,进而提高微网的稳定性与可靠性.在此前提下,利用博弈论寻找到与转移负荷用户及分时电价用户和储能方的Nash均衡点,达到光储微电网的最大收益.At present,the optical storage microgrid is fully understood and studied in order to maximize the economic benefit of the optical storage microgrid,and at the same time,the stability of the optical storage microgrid can be guaranteed.A new optical storage microgrid operation strategy based on demand-side response emerges as the times require:changing the service time of transferable load according to the needs of users,rescheduling the use of transferable load,reducing distribution capacity in the low valley stage and releasing load in the peak period of power consumption,customizing different electricity prices in different time periods,artificially regulating the demand for electricity,making the rational use of power resources,Then the stability and reliability of the microgrid are improved.On this premise.The game theory is used to find the Nash equilibrium point with the transfer load user,the time-sharing electricity price user and the energy storage party,so as to achieve the maximum benefit of the optical storage microgrid.
