Power resilience enhancement of a PV-battery-diesel microgrid

This work describes a methodology to evaluate a hybrid microgrid's energy resilience comprising a photovoltaic, battery, and diesel generator. This paper aims to figure out the optimized dispatched energy for different interruption scenarios with an economic analysis. It was observed that expanding power flexibility is conceivable by adding diesel generator with the microgrid model. Two different interruption scenarios have been developed by a power cut of 8 h and 72 h considering the major fault event. The result shows that the microgrid survives both outages through optimized energy dispatch, and the microgrid could spare 86,026 for the short time outage and for the prolonged outage, it could save 99,491 in energy over the 20-year project lifetime. © 2020 IEEE
