I. Introduction
With increasing wind power plants, conventional fossil fuel base synchronous generators are being replaced from generation fleet [1]. While wind energy offers several advantages from environmental aspects, it also causes technical challenges for system operation [2]. Most of the modern wind power plants are using power electronic device-based Type-3 (Doubly-Fed Induction Generator: DFIG) and Type-4 (Full Scale Converter: FSG) wind turbine generators (WTGs) [3]. These inverters have constrained capacities. Therefore, these WTGs provide lower fault current compared to synchronous generators of equivalent rating resulting deterioration in grid system strength [4].
