Experimental Study of an Inverter Control for Reactive Power Compensation in a Grid-Connected Solar Photovoltaic System Using Sliding Mode Control

In photovoltaic (PV) systems, inverters have an essential role in providing energy supply to meet the demand with power quality. Inverters inject into grid considering that a renewable source is available; however, during intermittent periods or absence of generation, inverter remains inactive, which decreases performance PV system. One way increase operation operate them as Volt-Amps Reactive (VAR) compensators generate reactive sources. The paper presents development control scheme allows system’s improve factor electrical system without generation. proposed based on using sliding mode controller (SMC) current loop and PI-based voltage loop. developed MATLAB/SIMULINK, for real evaluation, prototype implemented. strategy efficiency confirmed by obtained results. increases practical utility systems. Additionally, it improves all cases injection active operating under conditions and/or
