A survey of techniques for designing and managing microgrids

Recent trends of rising demands of electricity for supporting critical infrastructure have led to increasing interest in microgrids. Microgrids hold the promise of being the reliable and economically viable electric system which can greatly improve the efficiency, resiliency and eco-friendliness of future smart grid. Recently, several techniques have been proposed to managing microgrids. In this paper, we present a survey of techniques proposed for designing and controlling microgrids. The aim of this paper is to provide insights to the power-system engineers and researchers into techniques for managing the challenges of microgrids like voltage/frequency control, islanding, stability, power quality and economic optimization.
