Improvement of the performance stability of power grid with wind farms using static synchronous compensator

Abstract

The technological advancements in wind energy conversion have led to increased wind power generation in recent years. Static synchronous compensator (STATCOM) is used extensively in power systems due to its ability of providing the flexible power flow control. The main motivation for choosing STATCOM in wind farms is that it can provide bus bar system voltage support either by supplying or absorbing reactive power into the system, thereby can improve the steadystate stability limits of the network. This paper deals with the impact of STATCOM on the wind farm performance. The wind turbines considered are fixed speed ones with squirrel cage induction generator. In this work the performance of wind farm with and without STATCOM is investigated under fault conditions.
