摘　　要：随着我国风光电源近年来跨越式的发展,当前电力系统朝着构建高比例可再生能源系统体系的目标高速前进。与此同时,以火力发电为代表的传统电源占电力系统比例逐渐降低,导致了电力系统惯性下降以及调频能力减弱等突出问题。文中对新型电力系统下的多种潜在调频资源进行深入挖掘,从源-荷-储不同环节出发,梳理了风电机组、光伏机组、负荷资源以及储能系统参与系统调频的方式和原理。在此基础上,从考虑单一资源和考虑多种资源参与系统调频的角度,针对风光荷储参与系统优化运行问题进行总结,对比分析了优化模型中不确定因素的处理以及模型的求解算法。最后对系统优化调度中如何完善调度机制,合理安排新能源机组、负荷资源以及储能系统调频备用容量等问题进行了展望。With the great leap forward development of wind power in China in recent years,the current power system is moving towards the goal of building a high proportion of renewable energy system.Meanwhile,the proportion of traditional power sources represented by thermal power generation in the power system is gradually decreasing,which leads to the prominent problems of the decline of power system inertia and the weakening of frequency modulation ability.Therefore,this paper deeply excavates a variety of potential frequency modulation resources under the novel power system,and combs the ways and principles of wind turbines,photovoltaic units,load resources and energy storage system participating in system frequency modulation from the different links of source-load-storage.On this basis,from the perspective of considering single resources and considering multiple resources to participate in the system frequency modulation,this paper summarizes the problems of wind power storage participating in the system optimization operation,and compares and analyzes the treatment of uncertain factors in the optimization model and the solution algorithm of the model.Finally,how to improve the scheduling mechanism,reasonably arrange new energy units,load resources and frequency modulation reserve capacity of energy storage system in the optimal scheduling of power system is prospected.
