Modelling and Simulation of MPPT Algorithm for PV Grid-Connected System

This paper presents an equivalent circuit model of photovoltaic cells, and then discusses the photovoltaic (PV) grid power generation system in the maximum power point tracking (MPPT) control principle of the boost circuit. The MATLAB/Simulink software was used to model and simulate MPPT verification of the system. The simulation results showed the effectiveness of the control Strategy. As a conclusion, potential solution to MPPT The BOOST circuit adopts the MPPT control in photovoltaic power generation system, not only can improve the efficiency of photovoltaic cells, and thus improve the efficiency of the photovoltaic power generation systems.
