What is PQ Control Strategy in Single-Phase Inverter for Grid-Connected Photovoltaic Energy System Under Linear and Nonlinear Loads about?

In photovoltaic (PV) applications, single-phase inverters are commonly used for DC to AC power conversion interfaces. The most critical factor in evaluating the performance and quality of the inverter is to examine the output voltage and current. These outputs should be sinusoidal with low total harmonic distortion (THD) even when connected either to linear or nonlinear loads. This paper presents an improved inverter control strategy that is modelled in a PQ reference frame. The Hysteresis Current Control (HCC) is used to provide the switching signals for the inverter power switches. The PQ approach is also employed to control the power flow between the DC bus-inverter-grid. Based on the simulation results obtained, the proposed control strategy is capable of achieving robust current regulation, unity power factor, low THD and maximizing energy extraction from the PV arrays for supplying electricity to the power grid.
