Abstract:
As installed capacity of wind power retains a significant proportion of generation mix in the electric system, operators have the increasing expectation that wind turbines should function in some ways similar to the conventional plants. In addition to some basic capabilities to regulate reactive power for voltage support, the counterpart in active power control is also the major concern. This paper presents a control strategy to regulate active power for doubly fed induction generator under various operating conditions. Testing results showing the control performance in the simulated conditions validate the feasibility of the operation in power dispatch upon operator's request, and maintain stability under variant wind speed. Additionally, supplemental functions in generation margin assessment, in spinning reserve support, and in governor droop are presented to make the wind farm operation more like a conventional power plant.
