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.
What control strategies are available for microgrids?
Various control strategies are available for microgrids, including AI, Model Predictive Control (MPC), Proportional–Integral–Derivative (PID), and Fuzzy Logic Control (FLC).
Why do we need a control system for microgrids?
