Optimization and Performance Evaluation of Hybrid Renewable System for Minimizing Co2 Emissions in Libya: Case Study

Abstract

The current study focuses on reducing CO₂ emissions by developing and integrating a grid-based hybrid renewable energy system consisting of solar and wind or hybrid power system. Libya has its potential for generating developed economic power. Providing electricity as a case study to the modern University of Benghazi in Libya using HOMER to scale and model the power system and to assess its feasible solution and economic cost. Under different grid tariff scenarios, a simulation process of the four proposed grid tariff prices scenario.  In scenario A with a grid tariff of 5 cents, the optimal system was only for the local grid with an NPC of USD 41.824. Although in scenario B, with a grid tariff of 10 cents and an NPC of USD 83,651. There was no improvement in the optimum system, and only the best-proposed system was the local grid. Meanwhile, for scenario C, with a grid tariff of 15 cents, the optimum framework was USD 115.896 for the wind/grid with NPC. Whereas in the last scenario D, with a grid tariff of 20 cents, the optimum wind/grid device with NPC was also found at USD 136.081. Among the four scenarios, scenario C minimizing the optimum case CO₂ emissions by 50% compared to the grid-only system in scenario A.
