A Brief Analysis on Microgrid Control

Abstract

Microgrids have been an innovative enhancement in the power sector to integrate distributed power sources. Having the capability to operate in two modes, the control of microgrid is an important aspect to be studied. The paper discusses the operational concept and challenges faced by microgrids in different modes of operation to achieve optimum stability. The study on microgrid's control hierarchy has been analyzed in this paper. A brief analysis of several challenges faced by microgrid control strategy till-date has been discussed. Several power sharing strategies, energy management, and load balancing strategies have been studied. Along with the challenges faced, the paper explores future aspects of research in the field of microgrid control. IntroductionThe shifting power demand and environmental combat have been a constant source of change and development in the growth of power sector. Integration of distributed power sources earlier was restricted to medium and high voltage levels of power systems. However, the innovations, developments, and improvements in the miniaturized scale of power generation and distribution have promoted the use of distributed power sources at low voltage levels. This idea of integrating distributed sources in distribution networks has prompted the setup of microgrids addressing the demand
