Active Emergency Control Strategy for Wind Farms Considering Fatigue Load and Action Damage

Abstract

Abstract With the increase of renewable energy in power systems, the number of traditional coal power plants is decreasing year by year. The emergency control by tripping off the generators is no longer sufficient to maintain the stability of the system. Aiming to solve the problem with the help of wind farms, a cutting method based on reducing fatigue and motion damage is proposed. Firstly, FCM is used to select machines suitable for removal from the wind farm; then, an optimization model to minimize mechanical loss and output error is constructed by analyzing the shutdown process, and the cutter solution is obtained by solving the 0-1 planning problem; finally, the effectiveness of the proposed method is verified by example analysis.
