    Advantages of Utilizing the Solar Water Heating Technology in Reducing Total Electricity Consumption and Improving Grid Efficiency: A Case Study of Benghazi, Libya
    (Ieee, 2020) Almaktar, Mohamed; Hussein, T.; Rahman, Hasimah Abdul; Albreki, A. M.
    Fossil fuels based electricity is dominating in Libya. Nonetheless, the inefficient residential sector, particularly the electric water heating, is consuming a significant figure of the total electricity consumption, contributing to the blackouts which have been frequently hitting the country. Therefore, for a sustainable development and meeting the challenging present and future electrical energy needs, the energy efficiency (EE) and the renewable energy (RE) projects must be applied. The solar water heating (SWH) technology can play a vital role in reducing the electrical energy consumption, thus a contributing solution for the electricity shortage in Libya. More research and studies are needed to evaluate the efficiency, feasibility, and practicality of using the SWH in the residential sector. This paper investigates the electricity consumption and the performance of the national grid of Benghazi when the Electric Water Heaters (EWHs) of the end users are replaced with the SWHs. The analysis was done by using the Power System Analysis Software-NEPLAN. It was observed that a remarkable saving in electricity consumption (10-25%) and a better efficiency of the general electric transmission grid was attained in the case of utilizing the SWH technology. SWHs usually cost more to purchase and install than EWHs counterparts. However, SWHs can enhance the power system efficiency and reliability and also save money in the long run.

    Performance evaluation of different solar photovoltaic technologies in Libya
    (Ieee, 2020) Almaktar, Mohamed; Albreki, A. M.; Mohamed, Faisal A.; Yahya, Khalid; Hussein, T.
    Although Libya has a massive potential of renewable energy (RE) resources particularly solar energy, the country suffers from a shortage of electrical energy and experiences frequent blackouts. The dominant preventive action taken by the grid operator is to shed loads. The main two reasons for the limited RE projects are the highly subsidized electricity tariff and the absence of clear energy legislation. As a solution for the electrical energy deficit, this paper proposes the grid-connected photovoltaic (GCPV) power systems to be installed as distributed generations. The case study is based on a 1 MWp GCPV system designed for Benina International Airport (BIA) in Benghazi. Besides satisfying the electrical demand of the airport, the system can also export its energy directly to the electrical grid where the residential and commercial loads. The analysis was carried out by using PVSyst software. Four PV technologies were simulated for the installation for the sake of performance comparison under Benghazi's weather condition. It was concluded that cadmium telluride (CdTe) outperforms other technologies with 4.79 kWh/kWp/day of produced energy and a performance ratio (PR) of 78.11%. The project can be a successful showcase clean energy producer and a business model which can encourage the individuals and the governmental utilities to implement the solar PV technology for both electricity demand satisfaction as well as a profitable investment.
