摘要：
Aiming at the demand of power system for power quality, economy, load support and rapid response when large-scale wind power is connected to the grid, a multi-time scale coordinated optimization strategy with participation of variable-speed wind turbines in frequency regulation for the power system with high wind power penetration is proposed. The strategy considers the flexibility of load fluctuation and active output of wind power. According to operation characteristics of the variable-speed wind turbines, the flexible load reduction control of wind turbines under different wind speed conditions is established. Meanwhile, the frequency regulation output of wind turbines is coordinated at different time scales, which makes the inertia combined with primary frequency regulation to achieve frequency adjustment optimization. The results show that variable-speed wind turbines could effectively provide inertial support for the system and has flexible and controllable static frequency response characteristics. © 2019 Automation of Electric Power Systems Press.
