Real Time Design and Analysis of a Hybrid Renewable Energy System (PV/Wind/Battery) for Self-Consumption Residential Building

Abstract

The increasing research interest in Hybrid Renewable Energy Systems (HRESs) reflects a global desire for development and sustainability. Hybrid renewable energy systems aim to meet the energy demand loads, including residential loads, which constitute the largest electricity consuming sector in Libya, accounting for approximately 56% of the total electric energy consumed in the country in 2022. Consequently, this paper presents a novel approach by designing and analyzing a hybrid renewable energy system to cover the electrical load based on the power capacity of the devices and the actual operational time. The study relied on real-time measured data at 10-minute intervals for climatic conditions (solar radiation intensity, wind speed, and ambient air temperature) as well as the electrical loads consumed in a household located in Samno, Sabha, Libya. A dynamic simulation of the proposed system's performance was conducted using the SAM simulation software, and the results were processed using Microsoft Excel. The results showed that the proposed hybrid renewable energy system is capable of meeting the required electrical load, especially during peak times, and supplying power to the electrical grid. The economic results show that the levelized cost of energy (LCOE) is US$0.0107/kWh.
