An Improved P&O MPPT Method for Photovoltaic Power System

Abstract:

To improve the utilization efficiency of the solar energy with certain conversion efficiency, the principle of MPPT control with Boost converter is explained according to photovoltaic array output characteristics. The disadvantage of the conventional perturbation and observation (P&O) is analyzed. A novel MPPT system based on a digital signal processor (DSP) with Boost converter and an improved P&O algorithm is proposed in this paper. The proposed MPPT system model is developed under Matlab/Simulink. At last, theory analysis indicates its feasibility while the simulation results verify its validity.
