摘　　要：在微电网优化调度中,需求响应作为需求侧管理的重要措施起着重要作用。为更好地促进可再生能源消纳,首先,将风电机组、光伏机组、燃气轮机和电储能装置集成为微电网;然后,基于风光总出力特性构建动态响应电价机制;最后,以用户用电成本最小化和电厂发电成本最小化为目标,在不同电价机制下进行微电网的调度优化。研究结果显示:相较于固定电价和峰平谷电价,本文提出的基于风光出力不确定性的动态响应电价机制更能够有效降低用电成本和发电成本,提升可再生能源的利用效率,实现微电网的优化运行。In the microgrid optimization scheduling, demand response plays an important role as important measures for demand side management. In order to better promote renewable energy, first, the wind turbine, photovoltaic unit, gas turbine and electrical energy storage device are set to the microcrateline, and then the dynamic response electricity price mechanism is constructed based on the overall performance characteristics of the scenery, and finally, in the user’s electricity The minimization of cost and the minimization of power generation costs are the target, and the scheduling optimization of the microgrid is performed under different electricity price mechanisms. The results show that the dynamic response electricity price mechanism proposed based on the fixed electricity price and peak valley is more effective to reduce electricity cost and power generation cost, enhance the utilization efficiency of renewable energy, and achieve microgrid. Optimization operation.
