Title:
GENERATOR DISPATCHING OR LOAD SHEDDING CONTROL METHOD AND SYSTEM FOR MICROGRID APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2014/058571
Kind Code:
A3
Abstract:
A microgrid power generation system (80) includes a plurality of generators (200,202) having a plurality of different rated capacities and a plurality of distribution nodes (210,212,214), at least some of the distribution nodes being powered by the generators. A grid (208) is formed by the distribution nodes, the grid includes a system frequency (302). A plurality of loads (216,218,220) are powered by the grid through the distribution nodes, the loads have a power demand. A processor (230;216;218;220) includes a plurality of efficiency bands (88,92), each of the efficiency bands being for a corresponding one of the generators and including a plurality of generator switching points based upon droop of the system frequency and the power demand of the loads. The processor is structured to operate the generators and the loads under transient conditions based upon the efficiency bands.
