A microgrid comprising an interconnected solid oxide fuel cell and hydraulic generator for use in a sustainable city
Direct current systems that lack an inertial force, such as fuel cells or photovoltaics, are expected to be used for electrical power in advanced sustainable cities. A small-capacity transmission network (microgrid) without inertial force has difficulties for converging short-term electric power flu...
