Enhancement of Transient State in MPPT Techniques for PV Grid Connected System

Abstract

Instead of using non-renewable energy sources, industry researchers have wide applications in renewable energy sources such as hydro, wind and solar which are highly preferable because of having huge advantages like easily erectable and abundance in environment. For obtaining the high quality in electric power system, the system requires special conditions while connected to the grid. This paper shows the interfacing of Photovoltaic system connected to 3-phase grid. To ensure the highest output power of Photovoltaic system, a DC to DC converter with Maximum power point tracking (MPPT) is required. In this work, comparative analysis has been carried out for the MPPT techniques with topology β- method which is connected in parallel to perturb and observe method. The above proposed method enhances the dynamic performance of the system and effective under the steady state as well as transient state. The proposed system is implemented and simulated in MATLAB/Simulink. Analysis of simulation results are carried out for validation of system.
