可再生能源对于为孤岛电力系统供电具有吸引力。当光伏系统（PV）渗透率变大时，电力需求无法消耗掉所有的光伏发电量，而是需要削减光伏发电量。热泵热水器和电池储能系统的需求响应（DR）可以减少弃电。供水系统也适用于 DR 资源，因为许多供水系统都有大型水箱或水坝作为蓄水池。为了充分利用水厂系统的巨大灵活性，需要对DR资源进行多日协调控制。本文构建了具有多个DR资源的孤立电力系统的优化模型，作为制定协调控制方法的第一步。对比2周优化和1天优化的容灾资源运行情况，分析5种光伏容量设置下的长期规划效果。仿真结果表明，DR协调控制的合适规则根据季节和光伏装机容量的不同而不同。
Renewable energy sources are attractive for supplying electricity to isolated island power systems. When the penetration rate of Photovoltaic Systems (PVs) becomes large, the electricity demand cannot consume all of the PV output, but the PV output needs to be curtailed. Demand Response (DR) of heat pump water heaters and battery energy storage systems can reduce the curtailment. Waterworks systems are also suitable for DR resources because many of the waterworks systems have large tanks or dams as water storages. In order to utilize the large flexibility of waterworks systems fully, multi-daily coordinated control of the DR resources will be needed. This paper constructs the optimization model of the isolated power system with several DR resources as a first step of making coordinated control method. Comparing the operation of DR resources between 2-weeks optimization and 1-day optimization, the effect of long-term planning is analyzed with 5 PV capacity settings. Simulation results indicate that the suitable rules of DR coordinated control differ according to the seasons and installed PV capacity.
