Based on the previous control of the inverter’s output unit power factor, a reactive power compensation control strategy for single-phase solar power inverters is proposed. Use instantaneous no-power theory to realize the effective power control and reactive power compensation of the inverter, and optimize the function of the inverter.
The control goal of the inverter system is to synchronize the output of the current connected to the grid with the power grid, so that the system always outputs at maximum power. In the single-stage topology used in this system, the transformer only plays the role of voltage boost and electrical insulation.
The efficiency is the output power of the inverter divided by the input power of the inverter, which reflects the solar energy utilization rate of the solar power grid-connected inverter. The power factor represents the performance of the grid-connected current for synchronously tracking the grid voltage.
In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. . Of these, constant power control is primarily utilized in grid-connected inverters to control the active and reactive power generated by the PV system .
