孤岛微电网短路故障下跟网型逆变器电压支撑能力的增强

Nowadays, an islanded microgrid based exclusively on power electronic converters is a feasible scenario, in which one power converter is configured in grid-forming mode and the other converters in grid-feeding mode. In the event of a short circuit, the grid-forming inverter typically employs a virtual output resistor to limit the maximum current, which results in a voltage sag across the entire sy...
