An improved direct voltage control (DVC) strategy is proposed for the control of terminal voltage and frequency of a stand-alone wind-driven self-excited induction generator with variable loads. The DVC strategy, including a proportional-integral (PI) regulator, lead–lag corrector, and a feed-forward compensator, is designed based on the system transfer function matrix. The PI regulator can eliminate...
This paper presents the analyzed results of using a static synchronous compensator (STATCOM) to perform both damping improvement and reactive power-voltage (Q-V) control of a large-scale wind farm (WF). The studied 80-MW WF consisting of forty 2-MW induction generators (IGs) is simulated by an equivalent 80-MW IG connected directly to a utility grid through an equivalent step-up transformer and an...
A control method for standalone wind energy conversion systems with induction generator and energy storage system (ESS) is proposed in this paper. A fixed-speed self-excited induction generator is directly connected to the standalone power system. An ESS is employed to compensate the power variation from wind generator and load, maintain the power flow balanced. A direct voltage control scheme is...
