Reliability aspects in microgrid design and planning: Status and power electronics-induced challenges

Microgrids are highlighted as the technology which can help in providing sustainable and efficient electrical energy solutions. They employ distributed resources to efficiently supply local load increase reliability of network. Design planning a pivotal importance yielding all advantages this concept provide. Reliability-oriented design is special interest for microgrids utilizing large share renewable energy-based, power electronics-interfaced resources. A state-of-the-art overview included paper has shown that main reliability-oriented microgrid improvements done field sizing scheduling combined with relevant forecasting optimization methods. It is, further on, concluded standard system assessment within often excludes wear-out failure electronics. However, previous experience electronics prone have adverse impact on electronics-dominated system. Therefore, it necessary adjust current methods enable accurate investigation its design. To do so, characteristics modelling concepts together recent publications bridging discussed detail. Finally, findings serve basis development new procedures future, microgrids. • Microgrid important assuring high reliability. Overview practices helps indicating critical parts will be dominated by interfaced Excluding finding optimum solution. New incorporating electronic need developed.
