OPTIMISATION OF SOLAR PHOTOVOLTAIC SYSTEM EMPLOYING DISTRIBUTED MPPT CONTROL

This paper presents simulation and modeling with optimization and analysis in solar photovoltaic systems, as well as the role and potential of maximum power extraction with controller. Matrix calculations for grid inverters with data graphing, their functions, MPPT algorithm applications, user interface design for monitoring PV modules, and interaction with inverter and converter are all aided by simulations of renewable energy systems. It looks at how well they work on a single-phase grid with a PV system. Simulink model for solar energy conversion systems allows you to examine the performance of Photovoltaic cells, modules, arrays, Maximum Power Points and inverters. Controllers are being tracked when the environment and physical variables change. A distributed MPPT scheme, which allows adjustment of each DC-link voltage, may be adopted for PV systems to achieve maximum PV module usage and solar energy extraction. The pattern that has been developed allows for independent management of each DC-link voltage in order to track the MPP for each string of PV panels. For various operating circumstances, simulation results are provided.
