Coordinated Dispatch of a Power System with High Wind Power Penetration During Typhoon

Abstract

Frequent typhoons may threaten the operation security of coastal power system with high wind power integration, inducing severe wind power rapid climbs and line active power violations. Aiming at the phenomenon and problems in real typhoon disasters, this paper proposes a multisource coordinated dispatching strategy for high wind power penetration system under typhoon environment. In this paper, a wind farm output model considering wind speed is established. Besides, the profiles and fitting effects of different wind fields are compared. In the end of this paper, a multi-objective security constrained economic dispatch strategy during typhoons is proposed. The analysis of the regional system validates that the proposed dispatch strategy is feasible for the security improvement of the power system during typhoons.
