Systems, apparatus, and methods for automatic generation control islanded operation
First Claim
1. A power distribution system comprising:
- a plurality of power generating resources operating within a control area;
a plurality of power consuming loads;
a power transmission network coupling the resources to the loads; and
an energy management system in communication with the resources and configured to control operation of the resources within the control area, wherein the energy management system is operative to;
divide the control area into a plurality of isolation areas in response to detecting that isolation areas have occurred within the control area,assign at least one of the resources to each of the isolation areas,disable operation of the control area,enable each of the isolation areas to operate as an island having automatic gain control,balance a generation level and load level for each isolation area, anduse load frequency control to stabilize operation of each isolation area.

Abstract
Embodiments provide systems, apparatus, and methods for power distribution during islanding conditions. Embodiments include power generating resources operating within a control area; power consuming loads; a power transmission network coupling the resources to the loads; and an energy management system in communication with the resources and configured to control operation of the resources within the control area. The energy management system is operative to divide the control area into a plurality of isolation areas in response to detecting that isolation areas have occurred within the control area, assign at least one of the resources to each of the isolation areas, disable operation of the control area, enable each of the isolation areas to operate as an island having automatic gain control, balance a generation level and load level for each isolation area, and use load frequency control to stabilize operation of each isolation area. Numerous additional aspects are disclosed.
