Design and simulation of Hybrid Renewable Energy System for on-grid applications

Abstract

A hybrid renewable energy system (HRES) refers to a system that uses a combination of RESs such as wind and PV solar energies to improve and increase energy production and system efficiency. Since one energy source is used to provide electricity, the other one may be available or unavailable. This study is dealt with the design and analysis of a grid connected HRES conversion based on PV solar and wind turbine energy sources that use a DC converter and a permanent magnet synchronous generator. The goal of this work is to suggest a better dc bus voltage regulation approach for PV/Wind power generation systems that are grid-connected. To get a maximum amount of power generation, a maximum power point tracking controller based on Perturb and Observation algorithm is used. This approach improves efficiency and reduces harmonic content problems. The THD value of the output voltage was 0.94%. The HRES is built and modelled by the MATLAB program.

Modeling and simulation of PV system with three phase inverter along PV, IV curves using MATLAB/Simulink

“…Sizing the Inverter is to select an appropriate inverter, you need to consider the AC output power and the inverter's power rating. The inverter's power rating should be equal to or greater than the calculated AC output power [7]. It's important to consider any potential future expansions or changes in the PV system when selecting the inverter's size.…”
