Central power system failures have persisted as a result of the microgrids' instability. Microgrid technology integration at the load level has been the main focus of recent research in the field of microgrids. The conventional power grids are now obsolete since it is difficult to protect and operate numerous interconnected distributed generators.
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.
NLR researchers have developed and tested advanced inverter control algorithms that “self-synchronize” when a utility voltage is not present. Under loss of utility power, a microgrid must regulate voltage and frequency within the grid, and therefore these controls would be well suited to microgrids.
The state of the art on microgrid operation typically considers a flat and static partition of the power system into microgrids that are coordinated via either centralized or distributed control algorithms. This approach works well on small- to medium-size systems under normal or static operating conditions.
The microgrid controller functions as the system's central command, coordinating all these diverse power components. . A microgrid is a localized group of electricity sources and loads that typically operates connected to the main centralized grid.
