(IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 12, No. 6, 2021 Feasibility Study of a Small-Scale Grid-Connected PV Power Plants in Egypt; Case Study: New Valley Governorate Mahmoud Saad 1 , Hamdy M. Sultan 2 , Ahmed Abdeltwab 3 , Ahmed A. Zaki Diab 4 Dept. of Electrical Engineering Faculty of Engineering, Minia University Minia, Egypt Abstract—The construction of photovoltaic power plants (PVPPs) in the right place is an important task when planning the development of the power system and choosing investors. In this paper, the technical, environmental, the economic feasibility of installing a 50kW solar power plant in different places in the New Valley Governorate in Egypt has been presented using RETScreen Expert software. The input data used in the current study are obtained from the database of the Surface Meteorology and Solar Energy Dataset of NASA. In general, five sites for the construction of 50 kW power stations were assessed which represent the five administrative regions of the New Vally governorate. The study is based on annual electricity production, greenhouse gas (GHG) emissions, and financial analysis. With the proposed PV power plant, up to 100 MWh of electricity can be produced and a minimum of 43.3 tons of GHG emission can be prevented from the exhaust into the local atmosphere annually The obtained results from the RETScreen program proved the viability of installing the proposed 50kW photovoltaic power plant in any of the proposed locations. This study could give a piece of important information and feedback that can be utilized as a database for upcoming investments in the photovoltaic generation projects in Egypt.

INTRODUCTION Renewable Energy is the energy that can be extracted and derived from renewable natural resources or that cannot be exhausted or developed (sustainable energy). There are several fundamental differences between renewable energy sources (RES) and fossil fuels, which include "coal, natural gas, and petroleum" or "nuclear fuel that can be used in nuclear reactors". Usually, new and renewable energy does not generate harmful wastes such as carbon dioxide or harmful gases or increase the danger regarding global warming, compared to what can happen when burning fossil fuels or harmful atomic waste and waste from nuclear power reactors Renewable energy can be produced from the sun and wind. And water [1]. It can also be produced from tidal movements and waves, or geothermal energy, in addition to some productive trees and agricultural crops. Renewable energy has several advantages and benefits, direct or indirect, summarized in the following points: Renewable energy is not running out; It can also provide clean energy free of waste; it aims to protect human health; it can preserve the natural environment; it has Low production cost; it can improve human livelihood and reducing poverty; it can secure new job opportunities. Moreover, renewable energy has extra advantages like Reducing harmful gaseous and heat emissions and their dangerous consequences; Reducing greenhouse gas emissions and harmful heat and their dangerous consequences [2]; Reduced numbers and risks of natural disasters resulting from global warming; Not to form acid rain that harms all crops, agricultural products, and all different life forms; offering a significant reduction in the formation and accumulation of harmful waste in all its forms (gaseous, liquid and solid); Protecting all living organisms, especially the endangered species; Protecting groundwater, seas, rivers, and fisheries from the risk of pollution; Contribute to ensuring food security; In addition to increasing the productivity of agricultural crops as a result of eliminating chemical and gaseous pollutants [3]. The sun is one of the largest sources of light and heat on the face of the earth, and this energy is distributed over the parts of the earth according to its proximity to the equator, and this line is the area that receives the largest share of that energy, and the thermal energy generated by the sun's rays is used by converting it into (energy Electricity) by panels (solar cells). There are also two methods of collecting solar energy. The first one is that the sun’s rays are focused on a collector employing convex mirrors. The collector usually consists of several tubes containing water or air [4]. The sun’s heat heats the air or turns water into steam. The second method, in which a level plate collector absorbs the sun's heat, uses the heat to produce hot air or steam. The geographical location of the Arab Republic of Egypt is between latitudes 22 and 31.5 north, and as a result, Egypt is located in the depth and value of the global sunbelt. As a result, Egypt has been considered one of the world's richest countries with solar energy [4]. Where the Ministry of Electricity and Energy conducted a lot of research and studies to determine and clarify the characteristics of solar radiation in the Arab Republic of Egypt, which resulted in updating information, data, and statistics that were provided by meteorological stations and centers and adding many new stations and modern measuring devices. According to the various economic events and developments that Egypt has gone through during the modern era and their clear impact on the projects implemented 624 | Page www.ijacsa.thesai.org
