Design of a Resilient and Eco-friendly Microgrid for a Commercial Building

Recent natural disasters such as hurricanes Harvey and Maria have caused great disruption to the electric grid system. Additionally, government authorities set ambitious goals reduce greenhouse gas emissions. Thus, there is a growing interest in making power systems more resilient while reducing their carbon footprint. In this work, we used HOMER Grid software model behind-the-meter microgrids consisting of PV, battery, generator, load an office building that consumes average 2 MWh per day. We varied component sizes determine configuration with lowest generator size provide during two-day outage summer peak load. Environmental economic analysis were performed show tradeoffs between different system design goals. The results indicate installing microgrid 600 kW PV array 2.8 lithium-ion battery can avoid release up 287 tons CO2 year. same endure blackout highest demand hurricane season without need polluting backup generator. Microgrids will play important role transition smart because they reliable power, make grid-failure tolerant, allow high penetration renewable energy into which consequently reduces environmental impact.
