Title: UNINTERRUPTED POWER SUPPLY SYSTEMS AND METHOD FOR THE OPERATION THEREOF
Abstract:
Provided is an uninterruptable electrical power supply system (100). The system (100) includes an electrical power distribution network (108) having a consumer side network coupled to one or more electrical loads (104) that consume electrical power and a utility side network that supplies electrical power to the consumer side network. a primary power source (102) coupled to the utility side network, and that supplies electrical power to the utility side; a secondary power source (106) coupled to the utility side network, and a terminal between the consumer side network and the utility side network. The secondary power source (106) or UPS supplies power to the utility side network in response to a power shortage on the utility side network and sinks power from the utility side network in response to a power surplus on the utility side network (400). There are various energy storage modules or power drivers (200) the uninterruptible power supply (106) can have, based on different technologies. The power drivers (200) are operated hierarchically.
