In order to solve the problems of low utilization rate of distributed photovoltaic grid-connected inverters and high cost of power quality control at the end of the distribution network
a control method for a three-phase four-wire multi-functional photovoltaic grid-connected inverter was proposed. By analyzing the urgency of the demand for photovoltaic power generation
reactive power compensation
harmonic control and three-phase imbalance compensation at the end of the distribution network
the priority of photovoltaic power generation function and various power quality control functions is established
and the target current distribution method of multi-functional photovoltaic grid-connected inverter is proposed
so that the photovoltaic grid-connected inverter can output corresponding currents according to the priority of the power quality compensation for the distribution network. The simulation results show that this method can not only ensure the effective utilization of photovoltaic power
but also make full use of the residual capacity of the inverter to control power quality
improve the utilization efficiency of photovoltaic grid-connected inverters and reduce the cost of power quality control in distribution network.
