Evaluating the Techno‐Economic Feasibility of Grid‐Connected Hybrid Renewable Energy and Storage System

Abstract

Focusing on the renewable energy potential of Hurghada, Egypt, this study analyzes a grid‐integrated system that utilizes DSSC technology, wind turbines, and battery storage. A multi‐dimensional assessment is conducted, encompassing techno‐economic modeling, environmental impact through emissions tracking, and sensitivity analyses to evaluate system resilience under varying conditions. The optimization results indicate a decrease in the cost of energy (COE) from $0.149/kWh to $0.0485/kWh due to the integration of DSSCs, compared to a scenario relying solely on the grid. Additionally, the findings demonstrate that the proposed configuration can supply up to 85.6% of the required electricity. The study also compares grid power and DC voltage fluctuations with those of a system without storage, showing that the proposed system maintains stable DC voltage, which enhances overall system stability and power quality. CO 2 emissions drop drastically from 89,211 to 22,510 kg/Year, with similar reductions observed for SO 2 and NOx.
