Currently, conventional energy generators implement Automatic Generation Control (AGC) to regulate active power disturbance of power system attribute to wind power fluctuation after large capacity wind power integrated into grid. As an auxiliary means, wind farm would follow wind power schedule, adjust output plan in short-term and adopt emergency control in order to reduce the effect of wind power fluctuation on system stability and security. The performance of power system Peak load regulation and frequency control is increasingly affect by wind power's `peak-valley reversal' and high ramp rate, especially in high wind power penetration area. Therefore, it is necessary to improve and optimize power system active power dispatching strategy and AGC strategy to advance system admitting wind power ability. This article analyzes influence after large capacity wind power integrating on system active power dispatching and control first. Then, a real-time dispatching strategy is proposed which contains regulation volume distribution strategy and active power balancing model to resolve deviation of wind power output from wind power prediction in order to satisfy system real-time active power regulation requirement in operation. In the meantime, dispatching centre should properly utilize system regulation resource and acquire forecast information of wind power fluctuation in certain period of the future to reduce AGC adjusting pressure in regulating system unbalance between load and generation. Real-time dispatching Furthermore, coordinated control strategy between real-time dispatching of AGC is proposed to solve real-time dispatching order conflict to AGC order in operation and AGC regulation volume insufficiency. The approach and strategy are serving wind power reasonable integration and secure and stable operation of power system.
