摘　　要：针对全可再生能源孤岛微电网中的源荷功率平衡问题,研究基于抽水蓄能快速启停和强调节能力的风-光-抽蓄联合孤岛微电网电源与储能系统容量配置多场景鲁棒优化方法。针对海岛负荷需求特性及可再生能源、抽蓄资源分布特性,研究了适用于海岛的包含风、光、抽蓄和蓄电池组的孤岛微网拓扑结构模型;考虑海岛抽水蓄能及蓄电池电能储放特性、可再生能源出力不确定性以及岛内负荷需求不确定性,研究了微网功率协调优化方法,建立以孤岛微网成本最小为目标的容量配置鲁棒优化模型及其求解算法。以某海岛的实际负荷需求及可再生能源发电资源数据为基础的仿真结果表明,文章所提出的抽蓄联合孤岛微电网的容量优化配置方法,在实现经济性目标的同时,可以有效地提升可再生能源利用率和微网在多种场景下的运行可靠性。Aiming at the problem of source-to-charge power balance in fully renewable energy island microgrid,the multi-scenario robust optimization method of wind-solar-pumped storage isolated island microgrid power supply and energy storage system capacity configuration based on the rapid start-stop of pumped storage and strong regulation ability is studied.Aiming at the the island load demand characteristics and the distribution characteristics of renewable energy and pumped storage resources,the island micro-grid topology model including wind,solar,pumped storage and battery for islands is studied.Considering the charge and discharge characteristics of island pumped storage and battery energy storage,the uncertainty of renewable energy output and load demand in the island,the micro-grid power coordination optimization method is studied.A robust optimization model and solution algorithm for capacity configuration with the target of minimum cost of island microgrid is established.The simulation is based on the actual load demand of a certain island and the data of renewable energy power generation resources.The results show that the proposed capacity optimization configuration method of the pumped-storage joint island microgrid can achieve economic goals,and can effectively improve the renewable energy utilization rate and the microgrid's operational reliability in various scenarios.
