CONTROL OF SMALL DISTRIBUTED ENERGY RESOURCES

摘要

A power electronics interface (220) in a microsource (200) controller allows efficient connection in a power system of small, low cost and reliable distributed generators such as microturbines, fuel cells and photovoltaic. Power electronics provide the control and flexibility to insure stable operation for large numbers of distributed generators. The power electronics controls are designed to insure that new generators can be added to the syst em without modification of existing equipment. A collection of sources and load s can connect to or isolate from the utility grid in a rapid and seamless fashion, each inverter can respond effectively to load changes without requiring data from other sources, and voltage sag and system imbalances can be corrected.
