Method and apparatus for controlling a hybrid power system

摘要

The present invention provides a simplified method of controlling power among the various sources and loads in a power system (10). Power generating sources are each connected to a common DC bus (50) through a converter (20) designed to optimize power flow to the DC bus (50). A DC storage device (40) is connected to the common DC bus (50) through a power regulator (30) designed to maintain a constant voltage on the DC bus (50). Further, an inverter (60) may be provided to convert the DC voltage to an AC voltage for a customer load or for connection to the utility grid. Each power conversion device is independently controlled to provide a modular and simplified power control system (10).
