Model predictive control of PV-based shunt active power filter in single phase low voltage grid using conservative power theory

Abstract

Among different renewable energy sources, photovoltaic (PV) energy conversion systems connected to the grid via an interfacing converter have grown very fast. The system power quality is affected by nonlinear loads. This paper presents a control scheme for power electronics converters to mitigate current harmonics and control of the injected active power into the electrical grid which is generated by PV system. These objectives are achieved by using the conservative power theory (CPT). Finite control set model predictive control (FS-MPC), is used as proposed switching algorithm. Finally, simulation results using MATLAB-Simulink demonstrate the effectiveness and performance of the FS-MPC switching algorithm in comparison with hysteresis switching algorithm.
