该文构建以服务区微网净收益最大化为目标,以微网系统功率平衡为约束,包括蓄电池与氢能两种储能单元在内的风、光发电服务区微网优化调度模型。采用CPLEX求解器进行求解,并对纯蓄电池、纯氢储能、蓄电池与氢储能混合系统3种不同配置方案下的优化策略进行对比分析。研究结果表明:含氢储能的方案提升了风、光资源利用率的同时增强了系统供电可靠性,验证了该方案下优化调度策略的有效性。

A microgrid dispatch optimization model with wind and solar power generation,together with battery and hydrogen energy storage system,is proposed in this paper,in which maximum net income of the service area microgrid is employed as optimization objective and the power balance of the microgrid system is employed as the constraint.A CPLEX-based solver is adopted to analyze and optimize the problem,and three optimization schemes are compared for case study,which takes pure battery,pure hydrogen energy storage,and hybrid battery and hydrogen energy storage system into consideration respectively.Experimental results show that the hybrid wind and solar power generation microgrid with hydrogen energy storage system performs better on the indices of resource utilization and power system reliability simultaneously,which verifies the effectiveness of the method proposed in this study.
