Integration of Solar Energy in Smart Grid for Improved Energy Efficiency
Abstract
The global transition towards sustainable energy systems, coupled with the concerns over climate change, greenhouse gas emissions, and depletion of fossil fuels reserve has intensified the integration of renewable energy sources into modern electricity networks, and solar photovoltaic (PV) technology has gained significant attention due to its environmental benefits. The aim of this study is to investigate the integration of solar photovoltaic system in a solar energy smart grid system for improved energy efficiency. The study employed the MATLAB/Simulink environment model to simulate a grid-connected solar PV smart grid, and the result of the simulations shows that at different voltage and current plots of various components of the proposed grid, there is a direct proportionality between irradiance and PV generated current, while the voltage at the dc bus did not exceed the target 400V, MATLAB/Simlink model also enhanced smart grid performamnec, maintained stable voltage and frequency within the acceptable operating limits, reduced transmission and distriution losses, optimzed battery charging and discharging operations, and increased the ultilization of solar-generated electricity. The study contributes that MATLAB /Simulink-based smart grid model incorporating solar PV generartion, MPPT conrol, Battery energy storage, and enhanced energy efficiency.
