Abstract

 The new age of electricity generation is renewable energy. There is no other room, but to use renewable resources in energy generation to make the planet safer, and sustainable for the future. Renewable resources come in a variety of ways, but solar energy is by far the most practical. These days, solar panels are widely used due to their ease of use, accessibility, and efficiency in producing power. The Paper begins with a comprehensive review of existing literature on grid-tied inverters, including their functionalities, control strategies, and integration challenges. Based on this review, a novel topology is proposed, which incorporates perturb and observe technique and power electronics techniques to maximize energy conversion efficiency and grid stability. This Paper mainly represents the simulation of compact design of a grid-tied solar system for energy production using Maximum power point tracking. Several fundamental characteristics, including temperature, irradiance, voltage, and current, affect the efficiency of a solar panel. Hence sudden change in any of these parameters leads drop in power and voltage. The precept aim is to improve the output voltage of PV array and boost converter there by reducing the harmonic content in grid current. In this paper, MATLAB/Simulink software is used to simulate and analyse the operation of a PV array integrated with the utility grid through a two-stage power conversion system. This paper contributes to the ongoing efforts to enhance the performance and reliability of grid-tied inverters for solar PV applications.
