What is a microgrid?
Microgrids (MGs) represent one outcome of this transformation. The MG represent a compact power system comprising of independent renewable energy resources (RERs), energy storage systems (ESSs), and loads operating as a unified control system to generate power for localized areas within the range of 10–100 MW [3, 4].
How can a microgrid controller be integrated into utility operations?
A simple method of integration of a microgrid controller into utility operations would be through abstraction. High-level use cases are presented to the operator (ex., voltage regulation, power factor control, island mode), but most actual control is handled by the remote controller and not the power system operator.
