摘　　要：为了能达到光储微电网经济效益最大化,以及在经济效益最大化的同时,保证光储微电网的稳定性。从而提出一种新的基于需求侧响应下光储微电网运行策略即通过调整可转移负荷的工作时间,对可转移负荷进行重置安排,减少配电容量,以及利用不同用电时段制定不同的电价制度即分时电价,人为调控电力需求量,实现削峰填谷的效果,从而提高微网的稳定性。为了使得微电网有最大的经济收益,利用博弈论的方法,继而找到转移负荷用户、分时电价用户、储能方的Nash均衡点。In order to maximize the economic benefits of the optical storage microgrid and maximize the economic benefits,the stability of the optical storage microgrid is guaranteed.Therefore,a new operation strategy based on the demand side response of the optical storage microgrid is proposed,that is,by adjusting the working time of the transferable load,resetting the transferable load,reducing the distribution capacity,and making different use of different power consumption periods.The electricity price system is the time-sharing electricity price,artificially regulating the demand for electricity,realizing the effect of cutting peaks and filling the valley,thus improving the stability of the microgrid.Then use game theory to find the Nash equilibrium point of the load user and the time-of-use electricity price user and the energy storage party under the combination of the strategy,and achieve the maximum benefit of the optical storage microgrid.
