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).

Cette invention concerne un procédé simplifié de régulation de la puissance parmi les différentes sources et charges d'un système d'alimentation (10). Des sources de génération d'énergie sont reliées individuellement à un bus CC commun (50) à travers un convertisseur (20) conçu pour optimiser le flux d'énergie vers le bus CC (50). Un dispositif de stockage de CC (40) est relié au bus CC commun (50) à travers un régulateur de puissance (30) conçu pour maintenir une tension constante sur le bus CC (50). En outre, un onduleur (60) peut être prévu pour convertir la tension continue en une tension alternative pour une charge client ou pour une connexion au réseau public. Chaque dispositif de conversion de puissance est commandé indépendamment pour créer un système modulaire et simplifié de régulation de la puissance (10).
