BIDIRECTIONAL THREE-PHASE POWER CONVERTER FOR A MICROGRID
CITCEA UPC has designed and built a bidirectional three-phase power converter to be used between a battery or supercapacitor energy storage system and an experimental microgrid. This converter enables private power generation, storage and consumption to be integrated into the public grid. Thus, private generation can be considered by the public system as an intelligent, single entity that can supply itself independently, but can also support the grid, supply and consume energy, depending on the needs and/or shortfalls of the public electricity system. The power that is generated is integrated close to where it is consumed, which helps to relieve the power transmission system. The device was developed as part of a tender issued by CENER. CITCEA UPC has a replica of this device in its lab.
