Electrical Systems and Methods Using High Capacity Local Bus Supported by Energy Storage

A system includes a first bus configured to be coupled to a grid and a second bus configured to be coupled to a load and/or a source. A first converter is configured to couple the first bus and the second bus and a second converter configured to couple an energy storage device to the second bus. The system further includes a controller configured to control the first and second converters such that the second converter controls a voltage and frequency on the second bus by energy transfer between the energy storage device and the second bus and the first converter transfers energy between the first bus and the second bus.
