Abstract This paper presents real-time digital simulation-based modeling of a single-phase single-stage PV system. Discrete models of voltage source converter (VSC) controls, including proportional resonant (PR) current control and phase-locked-loop (PLL) are developed in RT-LAB. An improved incremental conductance-based maximum power point tracking (MPPT) method that can mitigate error signal spikes is proposed and modeled in RT-LAB as well. Simulation results demonstrate the faster response of the proposed MPPT and the real-time simulation performance of the developed system model.
