Dynamic and Transient State Analysis of Islanded Microgrid

Recent days have seen a high penetration of renewable energy resources bringing a drastic reformation of modern power system. The combined operation of renewable energy resources in power system introduced the concept of microgrid, which can efficiently satisfy the load demand in small scale power distribution. Under such circumstances microgrids are prone to several protection issues. Several topologies are incorporated to ensure protection in microgrid scenario. This paper proposes a proportional resonant based current controller which efficiently handles the protection issue under dynamic and transient state operation of microgrid. Several case studies are carried out in MATLAB Simulink environment and the results validated using proposed proportional resonant based microgrid model.
