The present invention provides a simplified method of controlling power among the various sources and loads in a power system. Power generating sources are each connected to a common DC bus through a converter designed to optimize power flow to the DC bus. A DC storage device is connected to the common DC bus through a power regulator designed to maintain a constant voltage on the DC bus. Further, an inverter 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.
