Photovoltaic Maximum Power Point Technique based on Incremental Conductance (InCon) Control Algorithm

Abstract

Maximum output power status can significantly improve the deployment rate of solar energy system. In order to get the maximum power output, issue of tracking maximum power point (MPP), reduced harmonics around MPP and improve efficiency of the solar power energy system, this paper presents the improved maximum power point tracking (MPPT) control technique algorithm on the basis of traditional Incremental Conductance (InCon) method. Nonlinear engineering model of solar cells is built in the “MATLAB/Simulink”, simulation software. Analyze the basic working principle of maximum power point control technology. Design the simulation model of conventional Incremental conductance method and compares the results with modified method. The main circuit of the system consist on DC Boost Converter. The simulation results illustrate that, the modified Incremental conductance (InCon) MPPT algorithm is realistic, fast tracking accuracy, efficient and the stability of output power are superior.
