Microgrid controller

A microgrid controller coordinates the sources, storage and controllable loads within a microgrid. It sets operating points for inverters and gensets, maintains spinning reserve, sheds and restores load, and manages transitions between grid-connected and islanded operation, including black start and resynchronisation.

A distinction that matters

A microgrid controller supervises the whole system; a genset or inverter controller controls one device.

GC

Symbols

Genset controller

A genset controller starts and stops the engine, monitors engine sensors, provides generator protection functions and, in paralleling versions, synchronises the set and shares load with other sources. Automatic mains failure versions also monitor the utility supply and control the changeover.
