MICROGRID CONTROLLER

OVERVIEW

Optimizes the contribution between renewable energy resources, energy storage systems, and diesel generators in microgridsCurtails the renewable energy resources during low load periods in order to prevent over-supply conditionsManages the energy storage system state-of-energyDispatches and switches between diesel generator(s) as needed Seamlessly transitions microgrids between Islanded and grid-connected configurations using anislanding contactor relay (SEL700G supported)Manages the site net output during grid-connected operationsProvides a real-time monitoring and control interface Reports the system status variables to upstream supervisory systems (i.e. SCADA, EMS, Data Historian)
