Coordinated energy management for an islanded microgrid with multi-energy and multi-storage units

Battery energy storage system is an attractive solution for stand-alone microgrid to make up the intermittent power of renewable energy sources. However, most studies on energy management are focused on the one-battery-unit condition while two or more battery units are recommended for system redunda...
