I. Introduction
Switched reluctance generator (SRG) is increasingly becoming a candidate for wind energy conversion systems (WECS), due to a number of advantages such as no need of rare-Earth permanent magnets and a gearbox, due to the low cost of their high pole structure, and high reliability [1]. At present, with the development of renewable technologies in distributed sources, there is the potential for changing the traditional power system to distributed generation (DG) like small microgrids (MGs). Since modern loads require a dc input and the SRG produces an inherent dc-like output voltage, the attention to the dc MG is growing very fast with concentration on the usage of SRG [2]. However, with the integration of a variety of power electronic converters, which act as constant power load (CPL), the negative incremental resistance behavior and their interaction with DG source may cause instability in dc MGs [3]–[5].
