Abstract
In order to improve the utilization efficiency of wind energy and reduce the wind energy curtailment as much as possible, this paper proposes an active power control strategy based on peaking and tie line constraints, which divides peaking and tie line absorptive capacity into dynamic zones. Through flexible switching of control modes in different zones, the utilization of peaking and tie line capacity can be maximized. Considering the situation that there is the non-energy dissipation of power grid due to peak load regulation or blocked cross-section, this paper proposes an echelon active power control strategy, taken into account the utilization of hours and the completion of trading power, thus, ensuring the fairness of the generating capacity of each station. The practical operation on a power grid system of northern part China demonstrates the feasibility of the proposed method.
