Toward Smart Microgrid with Renewable Energy: An Overview of Network Design, Security, and Standards

An increasing demand for efficient and safe electricity management has motivated the development of smart grid and accelerated the technical research for smart grid. On one side, a smart microgrid has been recently given an interest as a relatively small-scale, self-contained, medium/low voltage electric power system (EPS); it houses various distributed energy resources (DERs) with renewable energy and controllable loads in a physically close location. In this paper, we overview the research trend for the network design and security issues of smart microgrid, different from smart grid, and survey the effort of standardization for them. Through the survey, we derive the novel research issues to address for the successful realization of smart microgrid.
