Three-phase photovoltaic inverter control strategy for low voltage

Three-phase electrical systems are subject to current imbalance, caused by the presence of single-phase loads with different powers. In addition, the use of photovoltaic solar energy from single-phase inverters increases this problem, because the inverters inject currents of different values, which depend on the generation capacity at a given location.
