Voltage Control Scheme in Distribution Network with Double Feed Induction Generator Wind Farm

摘要

This paper presents the particle swarm optimization (PSO) for reactive power and voltage control (Volt/Var Control) in distribution system considering DFIG wind farm. In this paper, the reactive power output of DFIG wind farm has been considered as the control variables in the Volt/Var Control scheme by considering the reactive power compensation capability of DFIG. The minimization of total system real power loss and voltage deviation are utilized as an objective and the PSO is used to determine the reactive power output of DFIG wind farm, tap positions of load tap changer transformers (LTC) and numbers of the capacitor banks. Finally, the proposed scheme is applied to the 33-node distribution system. The results indicate that the proposed Volt/Var control scheme can improve the voltage profiles of distribution networks on a large scale.
