Abstract

Distributed power generation systems may be required to work in both grid-connected and stand-alone modes for ensuring the supply of critical local loads, maybe organized in micro-grids. Every time the micro-grid is disconnected and reconnected from the grid, a change in the control scheme is required leading to undesired transients and even lost of stability. In this paper, the use of the droop control is extended to both operation modes without commutating the control schemes. An islanding detection method is employed together with a synchronization algorithm achieving a successful micro-grid reconnection procedure. Simulation results prove the effectiveness of the proposed solution.
并网单机小型风力发电机组的通用控制器
分布式发电系统可能需要在并网和独立模式下工作,以确保关键的局部负荷的供应,可能组织在微电网中。每次微电网与电网断开或重新连接时,都需要改变控制方案,从而导致不期望的瞬变甚至失去稳定性。本文在不改变控制方案的情况下,将下垂控制扩展到两种工作模式。采用孤岛检测方法和同步算法,实现了微电网的成功重联。仿真结果证明了该方法的有效性。
