Abstract

With the increasing penetration of distributed wind turbines (WTs) in distribution systems, utilities are requiring these renewable resources to provide reactive power supports during steady-state and transient operating conditions. WTs with doubly fed induction generators (DFIGs) are able to independently control active and reactive power. The reactive power capability is subjected to several limitations resulting from the voltage, current, and speed, which changes with the operating point. This paper examines the reactive power control capability of DFIG-based WT by connecting it to the IEEE 14 bus distribution system. The stator-flux-oriented vector control principle is applied to build a model of the DFIG in dq synchronous coordination system, and the PSCAD/EMTDC simulation software is employed to investigate its performance in providing reactive power support to the grid.
