微电网包含多种分布式电源,组网时存在多能互补电源容量配置问题。以某一海岛微电网组网为例研究了微电网多能互补电源容量配置方法。通过案例分析,确定按计划离网配置适合选择保证综合负荷供电配置,而按非计划离网配置适合选择保证重要负荷供电配置。前者侧重于选择何时计划离网在满足综合负荷需求的情况下使投资成本最低,而后者侧重于任意时刻离网保证重要负荷可持续供电。另外,也可以综合两者对电源容量进行配置,既满足在计划离网时的综合负荷需求,又满足在非计划离网时的重要负荷需求。
微電網包含多種分佈式電源,組網時存在多能互補電源容量配置問題。以某一海島微電網組網為例研究瞭微電網多能互補電源容量配置方法。通過案例分析,確定按計劃離網配置適閤選擇保證綜閤負荷供電配置,而按非計劃離網配置適閤選擇保證重要負荷供電配置。前者側重于選擇何時計劃離網在滿足綜閤負荷需求的情況下使投資成本最低,而後者側重于任意時刻離網保證重要負荷可持續供電。另外,也可以綜閤兩者對電源容量進行配置,既滿足在計劃離網時的綜閤負荷需求,又滿足在非計劃離網時的重要負荷需求。

Microgrid contains multiple distributed resources, and the problem of capacity configuration for hybrid power occurs when microgrid is built. Taking the building of a certain island microgrid for example, the method of capacity configuration for hybrid power in microgrid is researched. Through case analysis, it is certain that the configuration meeting comprehensive load demand is suitable for capacity configuration on the basis of intentional islanding, while the configuration meeting significant load demand is suitable for capacity configuration on the basis of unintentional islanding. The former puts particular emphasis on the time of unintentional islanding for the lowest investment cost in the situation of meeting comprehensive load demand, and the latter puts particular emphasis on guaranteeing significant load sustainable supply whenever islanding occurs. In addition, capacity configuration can be carried out by combining both of them. As a result, not only comprehensive load demand can be met under intentional islanding, but also significant load demand can be met under unintentional islanding.
