APPARATUS AND METHOD FOR PROVIDING A POWER INTERFACE

摘要

Aspects and embodiments described herein are directed toward a power interface device including a first power interface configured to couple to an electric utility and a second power interface configured to couple to a microgrid comprising one or more power sources and one or more loads, the one or more power sources including a generator. The power interface device also includes a power conversion circuit coupled to the first power interface and the second power interface and a controller coupled to the power conversion circuit. The controller is configured to allow interfacing between the electric utility operating at a first frequency and voltage and the microgrid operating at a second frequency and voltage by at least detecting an operating frequency of the generator and controlling a power flow between the electric utility and the microgrid based on the operating frequency of the generator.
