Power generation redispatching to improve transient stability in power systems using controllability and observability gramians
Dynamic model of a variable speed wind generation system connected to grid is developed, and its steady state and dynamic performance is explored. The performance under wind gust and three-phase fault has been studied and the amount of transient injection to the grid is also investigated. A control scheme that minimizes the transient injection through a thyristor controlled variable capacitance at the generator terminal is proposed and developed. Fuzzy logic based controller is included in its control loop. Simulation results confirmed the effectiveness of the fuzzy logic controlled variable capacitance compensation scheme.
