Design approach of a resilient standalone hybrid AC/DC microgrid of multisource renewable energy with risk reduction strategy

A hybrid AC/DC microgrid takes momentum to replace the existing conventional AC microgrid, taking advantage of AC and DC microgrids. We propose microgrid architecture coupled with wireless networked devices for monitoring the microgrid components from a monitoring and control center. Moreover, a microcontroller-based architecture is proposed for cyber-risk protection. Thus, this paper presents a design methodology of hybrid AC/DC microgrid in isolated and remote rural areas, jointly with a resilience enhancement strategy. It also proposes availability, reliability, and resilience evaluation methods considering the distributed energy sources, including solar photovoltaic, wind generator, diesel generator, and battery bank. Finally, the most probable risk categories are discussed, and reduction options with mitigation techniques are suggested.
