摘要
随着间歇性电源(分布式风电、光伏)在中、低压配电网中渗透率的提高,多个微电网可能共存于一个区域配电网中,各微电网间能量互济与协调控制的微电网群技术开始引起广泛的关注。以微电网研究为基础,分析了微电网群的典型特征及拓扑结构。以微电网群功率波动为研究对象,建立了微电网群功率波动熵值的动态调度模型,采用量子粒子群优化算法进行求解实现优化控制。仿真结果验证了所提微电网群功率优化控制方法的正确性和有效性。
Due to the increased penetration of intermittent power generations(distributed wind power and photovoltaic power) in medium and low voltage distribution network,multiple microgrids may coexist in a regional distribution system,and therefore the microgrid cluster technologies of energy mutual-aid and coordination control have attracted wide attention. Based on the research of microgrid,typical characteristics and topology structure of microgrid cluster are analyzed. With power fluctuations of microgrid cluster as research objects,the dynamic dispatch model of power fluctuation entropy of microgrid cluster is established,which is solved by QPSO(Quantum Particle Swarm Optimization) algorithm to realize the optimization control. Simulative results verify the correctness and effectiveness of the proposed power optimization control method of microgrid cluster.
