Exploring Solar and Wind Energy as a Power Generation Source for Solving the Electricity Crisis in Libya

Abstract

The current study is focused on the economic and financial assessments of solar and wind power potential for nine selected regions in Libya for the first time. As the existing meteorological data, including wind speed and global solar radiation, are extremely limited due to the civil war in the country, it was therefore decided to use the NASA (National Aeronautics and Space Administration) database as a source of meteorological information to assess the wind and solar potential. The results showed that the country has huge solar energy potential compared to wind energy potential. Additionally, it is found that Al Kufrah is a suitable region for the future installation of the Photovoltaic (PV) power plant due to high annual solar radiation. Based on the actual wind speed analysis, Benghazi and Dernah are the best regions for large-scale wind farm installation in the future taking into account existing meteorological data limitations. The values of the wind power density in all regions are considerable and small-scale wind turbines can be used to generate electricity based on NASA average monthly wind data for 37 years (1982–2019). Moreover, this work aimed to evaluate the wind/PV systems technical and economically through RETScreen Expert (Version 6.0, CanmetENERGY Varennes Research Centre of Natural Resources Canada, Varennes, Canada). Focusing on the power supply crisis in the country, the potential of electricity production by 5 kW grid-connected residential/household rooftop PV in all regions is proposed and presented. Additionally, this paper evaluated a techno-economic analysis of the 50MW wind/PV system in suitable places. The performance of a 5 kW and 50 MW PV solar system with three PV technologies, namely mono-crystalline silicon, poly-crystalline silicon, and thin-film (CdTe), was also analyzed. The results demonstrated that the development of the wind/PV system in the selected regions is both technically and economically feasible. The outcomes of this study can help decision-makers in designing and installing PV power plants as an alternative source for the future.

A Techno-Economic Viability Analysis of the Two-Axis Tracking Grid-Connected Photovoltaic Power System for 25 Selected Coastal Mediterranean Cities

“…A FRONIUS SYMO 4.5-3-M LIGHT 4.5 KW SOLAR INVERTER with a capacity of 4.5kW and 98.6% efficiency was chosen in this study. The specifications of the selected PV panel and inverter are available at [22,23].…”

Techno-Economic Feasibility of Grid-Connected Solar PV System at Near East University Hospital, Northern Cyprus

“…The highest and lowest annual values of global horizontal irradiation in Northern Cyprus are estimated at 2000 kWh/m 2 and 1800 kWh/m 2 , respectively. These values indicate that the solar resource is classified as Energies 2021, 14, 7627 3 of 27 good (class 4) and excellent (class 5) according to Kassem et al [21] and Prăvălie et al [22]. Additionally, the maximum and minimum values of direct normal irradiation are about 2230 kWh/m 2 and 1710 kWh/m 2 , respectively.…”

Numerical Study of Ultra-Broadband Metamaterial Perfect Absorber Based on Four-Corner Star Array

“…The performance metamaterials are widely used in various fields due to their unique electromagnetic properties, such as metamaterial lenses [ 1 , 2 , 3 ], invisibility cloaks [ 4 , 5 ], surface sensors [ 6 , 7 , 8 , 9 ], wave absorbers [ 10 , 11 , 12 , 13 , 14 , 15 ], energy harvesters [ 16 ], etc. It is especially noteworthy that the energy crisis has brought new challenges and opportunities to all countries around the world [ 17 , 18 ], and solar energy has quickly won the favor of researchers because of its unique advantages. The research data show that the spectrum of solar energy radiation to the earth’s surface is mainly distributed in the range of 295–2500 nm, and nearly half of the energy is mainly concentrated in the visible region [ 19 ].…”
