Title: Design and Simulation of a Grid-Connected Photovoltaic Power System

Abstract: With the increasing demand for renewable energy sources, photovoltaic (PV) systems have become a popular choice for generating electricity. This paper presents the design and simulation of a grid-connected PV power system. The system consists of PV panels, a DC-DC boost converter, a DC-AC inverter, and a grid-tied inverter. The PV panels convert sunlight into DC electricity, which is then boosted to a higher voltage by the DC-DC converter. The DC-AC inverter converts the DC voltage into AC voltage, which is then fed into the grid-tied inverter. The grid-tied inverter synchronizes the AC voltage with the grid and feeds the electricity into the grid.

The simulation of the system was carried out using MATLAB/Simulink. The simulation results show that the system is able to generate electricity and feed it into the grid. The performance of the system was evaluated under different weather conditions and load conditions. The results show that the system is able to generate electricity even under low sunlight conditions and is able to meet the load requirements.

The paper also discusses the economic feasibility of the system. The cost of the system was estimated and compared with the cost of electricity generated from conventional sources. The results show that the PV system is a cost-effective solution for generating electricity.
