Abstract:Active power regulation in a wind farm has become a fundamental requirement to mitigate the adverse effect on the stable operation of grid.Frequent switching between running and stop state occurs due to ignoring operating conditions during the process of active power control.An active power control strategy for wind farms considering operating conditions is presented.First, according to the power forecasts and operating conditions, the margin queues for active power increase and decrease as well as the starting up and stop queues are created.Second, the power is distributed to wind turbines using active power distributing algorithm.Actual test in wind farm proves that the proposed control strategy not only can achieve rapid and accurate control of active power, but also can avoid frequent switching between running and stop state of the wind turbine, and reduce the failure rate of the wind turbine, and improve the stability and security of the wind turbine, and extend the service life of the wind turbine.
