Optimizing Grid-Connected Hybrid Renewable Energy Systems: A Case Study of Yanbu, Saudi Arabia

Abstract

This study presents an analysis of a grid-connected hybrid renewable energy system tailored for Yanbu, Saudi Arabia, combining photovoltaic (PV) arrays and a 20-kW wind turbine. Using the HOMER software, the research aims to optimize renewable energy integration into the grid while minimizing the total net present cost. Two scenarios are investigated: one without a minimum renewable fraction and another imposing a 50% renewable fraction limit. The unique environmental conditions of Yanbu, characterized by ample solar irradiance and wind resources, are leveraged to design a sustainable energy mix. Through detailed simulation modeling, the performance, cost-effectiveness, and environmental impact of the proposed system are evaluated. The objective function prioritizes maximizing renewable energy usage and cost efficiency, considering factors such as solar irradiance, wind speed patterns, and energy demand fluctuations. This research contributes valuable insights into optimal system configurations and trade-offs between renewable energy integration and cost effectiveness, thus facilitating the advancement of renewable energy technologies in real-world applications.

Keywords: Grid-Connected Energy Solutions; HOMER; Renewable Energy Fraction; Saudi Arabia.
