TL;DR: In this paper, the authors explore several operating strategies for doubly fed induction generators (DFIGs) to support system frequency with less sacrifice in the wind energy production, and show that the proposed strategies can enhance regulation performance in the high wind penetrated power system.

TL;DR: In this paper, a control strategy to regulate active power for doubly fed induction generator under various operating conditions is presented to make the wind farm operation more like a conventional power plant, and 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.

TL;DR: In this paper, the controllability of wind turbines under the set-point control was demonstrated and two types of wind farm models were derived and demonstrated to portray the capability of setpoint tracking under the intermittent wind condition.

TL;DR: An overall frequency restoration plan considering the DR and spinning reserve is proposed and test results show that the proposed spinning reserve and DR deployment could effectively restore frequency under various contingency scenarios.

TL;DR: In this article, a strategy that incorporates doubly-fed induction generator (DFIG) wind farms to actively provide primary reserve for frequency control is presented, and an integrated system that consists of the traditional units and DFIG wind farms has been developed to assess the frequency response and generating interactions.
