Incremental Conductance MPPT Method For Photovoltaic System

Solar power being a renewable energy resource has tremendous potential of usage in the imminent future and this paper is going to discuss an effective strategy to maximize solar energy harvest. This study has been done using MATLAB/Simulink combining solar modules, incremental conductance MPPT algorithm block and boost converter control block. Though solar energy harvest is dependent of irradiance, temperature and other climatic conditions it is imperative that a photovoltaic system operates at a maximum power point (MPP) in order to extract maximum energy from the system. The incremental conductance algorithm is an energy optimization strategy that provides fast dynamic response and well regulated photovoltaic (PV) output voltages. In addition, the number of parameter needed to be monitored are significantly lower than other algorithms, making the implementation much more streamlined and cost effective. This paper is going to discuss the observations of maximum power point tracking implemented on a solar power grid, thus augmenting its efficiency. Keywords— perturb-and-observe, maximum power point tracking, incremental conductance, boost converter.
