摘　　要：以水光互补微网逆变器的调度策略为研究对象,分析水光互补微网系统的拓扑和运行模式,微网逆变器的效率特点以及微网逆变器调度策略对微网系统能量转换效率的影响。提出基于动态规划的微网逆变器效率最优调度策略,讨论最优策略的求解方法,进行仿真并与常规的平均调度策略进行对比。仿真结果证明该调度策略可满足调度要求,并可减小逆变器损耗,提高微网系统的能量转换效率。Taking different scheduling strategies of Hydro/PV microgrid inverter as the research objective, the topology and operation mode of the Hydro/PV microgrid, the efficiency characteristic of the microgrid inverter and the influence on total efficiency of the mierogrid system were analyzed. The scheduling strategy of optimum efficiency based on dynamic programming was proposed. The solving method of the proposed strategy was discussed and the simulation was implemented. The proposed strategy can meet the requirement of the schedule, reduce the loss of the inverters and improve the total efficiency of the Hydro/PV microgrid.
