PROJECT TITLE :
Implementation of improved Perturb & Observe MPPT technique with confined search space for standalone photovoltaic system
ABSTRACT:
Solar photovoltaic technology has been adopted by varied world PV markets with 227 GW cumulative globally installed PV capability in 2015 replacing the standard fossil fuel energy resources. However, efficiency is still a huge challenge for researchers and PV business. This paper proposes a solar tracker and changed Perturb and Observe (P&O) algorithm for the standalone solar photo-voltaic system. Proposed algorithm confines the search house of the ability curve to ten% area that contains Most Power Purpose (MPP) and starts perturbation and observation at intervals that restricted search house. The proposed P&O algorithm was simulated in MATLAB/Simulink. Solar tracker makes sure the availability of uniform and maximum irradiance to the solar module throughout the course of the sun during the day. Confinement of the algorithm’s search area lessened the response time to the changing climate that in come decreases the steady-state oscillations at the MPP. Integration of the solar tracker and improved P&O MPPT algorithm provided the higher quality and conditioned electricity to the load. The proposed system was experimentally steered whose results verified the effectiveness of the proposed P&O algorithm.
