全资源调度下主动配电网削峰填谷优化运行研究

Research Onpeak Load Shifting Optimal Operation of Active Distribution Network Based on Whole Resource System Dispatching

针对主动配电网优化运行问题,构建一种全资源优化调度模型,以运行费用最小为优化目标,对分布式发电单元、储能单元、可切除柔性负荷等进行协调调度。针对构建的全资源优化调度模型,采用二次序列规划求解方法,并搭建MATLAB+OpenDSS仿真计算平台。以IEEE37馈线系统作为测试算例,分析不同电价信息下主动配电网采用优化调度后的削峰填谷效果,并进行了对比分析。

In order to realize the optimal operation of active distribution network,an whole resource system optimal scheduling model is established in this paper,controllable distributed energy resources,energy storage systems,and curtailable loads are coordinated,taking the lowest operating cost as the optimization objective.An algorithm based on the sequential quadratic programming and the MATLAB / Open DSS simulation platform are applied to solve the above economic dispatch problem.The model is demonstrated on IEEE 37-bus distribution system.The effect of peak load shifting under the optimal dispatch of active distribution network with different electricity price are analysed,and a comparative analysis is carried out.
