Abstract
PV cell has single operating point where the value of current and voltage results in a maximum power output. PV cell is directly connected to the load, the output power can be drastically reduced due to the load mismatching. It represents maximum power is not delivered from PV source to load. So it is necessary to provide a MPPT technique to extract maximum power from PV cells. In order to improve the power extraction from solar PV the MPPT technique should be accurate and fast. In this paper performance analysis of standalone solar PV system having Non inverting Buck Boost converter with sliding mode control MPPT and fuzzy logic control MPPT controller is carried out. A detailed Mathematical modeling is done to confirm the stability of the system. Detailed simulation is done in MATLAB/Simulink for validating the model. The instantaneous power corresponding to various insolation for sliding mode controller and fuzzy logic controller for extracting maximum power are obtained and compared. These power output is compared with conventional P&O method. SMC shows a very good response for tracking MPP and FLC shows smooth tracking. Hardware implementation is done, which confirms the validity of the simulation results.
