GRID-TIED VARIABLE FREQUENCY FACILITY

Abstract

A micro grid system comprises an adapter and a power controller. The adapter is in communication with an electric grid and configured to connect and disconnect a connection between the electric grid and a micro grid. The power controller is electrically connected to the adapter and receives first AC power from the electric grid via the adapter, obtains grid information, and controls the adapter to connect and disconnect the connection between the electric grid and the micro grid. The power controller controls the adapter to disconnect the connection between the electric grid and the micro grid in response to determining that the electric grid is abnormal based on the grid information.
