摘　　要：微电网的协调运行不仅要考虑整体最优化,也应兼顾微电网内部主体的经济效益最大化。文章计及用户需求响应和相关组件约束,建立了微电网"源-储-荷"两级协调运行的双层优化模型;上层规划模型以负荷转移策略前后的相对效益最大化为目标,下层规划模型以发电侧经济效益最大化为目标;以某微电网作为算例,验证了模型的有效性和合理性。仿真结果表明,可控负荷和储能系统的参与,可增强微电网的灵活性,减小负荷峰谷差;通过两级协调规划,有效地提高了微电网的整体综合效益和发电侧收益。This paper considers the user demand response and related component constraints,and establishes a two-level optimization model of the coordinated operation of "source-storage-load" in microgrid. The upper-level planning model aims at maximizing the relative benefits before and after the load transfer strategy, and the goal of lower-level planning model is to maximize the economic benefits of the power generation side. Finally, a microgrid in North China is taken as an example to verify the validity and rationality of the model. The simulation results show that:The participation of controllable load and energy storage system can enhance the flexibility of microgrid and reduce the peak-to-valley difference of load;The two-level coordinated planning can effectively improve the overall comprehensive benefits and the revenue of the power generation side.
