The project successfully demonstrated the microgrid controller’s ability to integrate and control the ESS, PV system and facility loads while connected to and islanded from the grid. This project was conducted at Marine Corps Air Station (MCAS) Miramar.
The project involves integrating the advanced Zn/Br Battery and Intelligent Power and Energy Management (IPEM) microgrid control technologies with the infrastructure at MCAS Miramar to provide energy security, islanding capability, and reduced costs. The demonstration connects MCAS Miramar’s Department of Public Works building to the ESS and solar photovoltaic (PV) system, enabling the building to receive power while disconnected, or "islanded", from the grid. The goal of the project is to peak shave and island the building circuit for 72 hours under controlled loads. The islanding duration is directly related to 3 main factors: battery energy capacity, PV system generation (solar resource), and load reduction.
