What are the key considerations in designing an electrical microgrid?

Microgrid design addresses: distributed energy resources (solar, generators, batteries) sizing and integration, point of common coupling (PCC) protection for islanding detection and reconnection, energy management system for optimal resource dispatch, power electronics for DER interconnection (inverters with grid-forming or grid-following capability), protection coordination changes between grid-connected and islanded modes, power quality maintenance during mode transitions, load shedding strategy for islanded operation, and compliance with IEEE 1547 for interconnection. Economic analysis justifies investment against utility rates and reliability value.
