Abstract
A system and method for establishing a microgrid from an existing electrical grid whereby the system provides a remote terminal that collects data from the electrical grid and the microgrid and communicates the data back to and from the microgrid and the electrical grid, whereby the remote terminal unit may continuously monitor specific parameters from the microgrid and the electrical grid, such as distributed generators, converters, and loads, including power levels, charge levels, voltage levels, current flow, temperature, breaker status, and other information pertinent to the microgrid and the electric grid, while the RTU is designed for microgrid islanding and power flow.
Claims16
A system for opening a microgrid for islanding from an existing grid, comprising:
- a remote terminal unit, wherein the remote terminal unit opens for the islanding from the existing grid, wherein the remote terminal unit is a unified power flow controller to control flow of power in the microgrid and the existing grid to independently control both active and reactive power flows in a transmission line between them, wherein the remote terminal unit is configured to:
- monitor voltage, current, and power level on the existing grid and the microgrid;
- control isolation of the microgrid from the existing grid during power disturbances or outages;
- manage power flow within the microgrid by monitoring voltages and currents at distributed generator sources within the microgrid;
- and
- determine storage capacity of the microgrid;
- generate a response when a predetermined voltage deviation occurs to counteract voltage sag or surge.
