摘要
文章表述了通过下垂控制方法,可达到改善微电网系统自主运行的目的,实现了基于全代码微电网的自主运行过程。本地分布式发电机的拓扑结构通常由并网逆变器和LCL滤波器构成,下垂控制旨在微电网孤岛效应发生后分散系统负载变化[1]。该下垂控制的优势是即使在瞬时阶段,也可以减少与额定频率之间频率的偏差。该方法的使用,使微电网从自主运行状态到并网运行状态的无缝转变得以实现。
This article describes the purpose of improving the autonomous operation of the micro grid through the droop control method, and realizes the autonomous operation process based on the full code micro grid. The topolo- gy structure of the local distributed generator is usually composed of grid connected inverter and LCL filter. Droop control is designed to change the load of distributed system after the isolated island effect of micro grid. The droop control advantage is that even in the instantaneous phase, it can also reduce the frequency deviation between the frequency and the rated frequency. The use of the method makes the seamless transition from the autonomous opera- tion state to the grid connected operation state.
