Solar Cell Connected To SEPIC Converter Using Various Loads for Power Tracking

Renewable energy can be categorized as a noticeable source for generation of electrical energy. Solar energy has acquired a prodigious importance in current generation. To harness this energy photovoltaic configuration is utilized. This paper defines simulation and mathematical analysis of a PV cell using SIMULINK/MATLAB. Electrical behavior of Photovoltaic cell is estimated in accordance to environmental parameter changes such as irradiation and surrounding temperature. To obtain significant results simulation is exploited at Maximum Power Point (MPP) using an efficient Maximum Power Point Tracking (MPPT) Algorithm. This paper enumerates implementation of Perturb and Observe Algorithm for MPPT using SEPIC converter. This model deals with V-I characteristics and P-V characteristics as well as estimation of voltage, current and power at MPP. A meticulous comparison between MPP using P&O and without using P&O are analyzed and presented. On comparison simulations shows that P&O method is able to track MPP competently and more effectively.
