Abstract
A reactive power support system for a radial distribution network includes multiple loads, a radial distribution transmission line (RDTL) connected at a first end to a grid transformer, a point of common coupling (PCC) connected to a second end of the RDTL, a solar power inverter connected in parallel with a photovoltaic module and an inverter controller connected to the inverter. An output terminal of the inverter is connected to the PCC. Each load is connected by a load bus to the RDTL. The inverter controller provides gate control signals which switch a set of transistor gates of the inverter to operate at less than or greater than a unity power factor to inject or to absorb the reactive power, respectively, at the PCC in order to regulate a voltage of the RDTL during a three-phase to ground fault on a load bus connected to one of the loads.
