摘要
当需要对孤岛微电网进行规划设计、可靠性评估或者优化调度时,通常需要对孤岛微电网在一定时间内的运行状态进行连续模拟,以掌握孤岛微电网的实际运行特性。本文提出一种计及时序特性的孤岛微电网运行模拟方法,首先建立计及下垂控制策略的孤岛微电网潮流计算模型,其次充分考虑储能充放电、切负荷以及弃发电策略,提出计及时序特性的孤岛微电网运行模拟流程,最终以Benchmark 0.4k V低电压微电网以及实际数据进行算例分析,验证本文方法的有效性。
Usually continuous simulation of the running status of the island microgrid during a certain period will be done to get the actual operation characteristics of the grid when design, reliability assessment or optimal dispatching is made on island microgrid. The paper presents an operation simulation method with time-sequence characteristics for island microgrid. First, power flow model with droop control strategy is built. Secondly, simulation process with time-sequence characteristics is put forward, and the charge and discharge of energy storage, load shedding and abandoning power strategy are fully considered. Finally, the effectiveness of this method is verified by an example of Benchmark 0.4 k V low voltage microgrid and actual data.
