The large-scale integration of Solar photovoltaic (PV) systems in the distribution grid has introduced several technical challenges such as voltage variations, reverse power flow, power quality and harmonics. These issues are more pronounced in weak grids. Therefore, modern power inverters with the capacity to complete Volt-Var control and moderate power outputs are required to increase grid stability in weak and/or microgrid installations. This paper investigates the use of a Continuous Control Set Model Predictive Control (CCS-MPC) algorithm to control a solar PV inverter, moderating active, and reactive power transfer into the grid through an iterative process. A MATLAB Simulink model is produced and tested to validate the proposed algorithm, with a scenario showing reactive power compensation through Volt-Var control curves. The simulation results confirm that the MPC controller can regulate power flow into the grid with enhanced dynamic and steady state performance, and improved power quality.
