摘　　要：针对电网中可再生能源发电占比与弹性资源不断增加的趋势,提出一种计及源荷双侧弹性资源的日前调度鲁棒优化方法,以应对可再生能源发电不确定性给电网调度运行带来的挑战。首先,根据可削减负荷和可平移负荷的响应特性,分析了补偿价格对前者的最大可削减容量以及后者的可接受平移时段的影响关系,建立了负荷侧弹性资源模型;其次,考虑风电出力不确定性,并基于火电机组深度调峰及负荷侧弹性资源模型,建立了柔性负荷补偿价格−调用量联合优化的日前调度鲁棒优化模型;最后,通过算例分析验证了所提模型与方法的有效性,结果表明,考虑源荷双侧弹性资源可调度潜力的调度方法能有效提升电网运行鲁棒性与经济性。In view of the increasing trend of renewable energy generation and flexible resources in the power grid,a robust optimization method for day-ahead dispatching considering the flexible resources of both source and load sides is proposed to cope with the challenges brought by the uncertainty of renewable energy generation to the dispatching operation of the power grid.Firstly,according to the response characteristics of reducible loads and shiftable loads,the influence of compensation price on the maximum reduction capacity of the former and the acceptable translation period of the latter is analyzed,and the flexible resources model of load side is established.Secondly,considering the uncertainty of wind power output,based on the model of deep peak regulation and flexible resources on load side,a robust optimization model for day-ahead dispatching is established,in which the compensation price and adjustment quantity of flexible loads are jointly optimized.Finally,the effectiveness of the proposed model and method is verified by an example analysis.The results show that the dispatching method considering the schedulable potential of flexible resources of both source and load sides can effectively improve the robustness and economy of power grid operation.
