Estudo de viabilidade técnica para implementação de uma central fotovoltaica de 10 mw ligada a rede na vila de Lindela

Abstract

According to the latest SDG7 Tracking Report 2021, Mozambique faces a significant deficit in electricity access, placing it among the 20 countries with the lowest access over the period 2010 to 2019. Although there has been an increase in access to grid electricity from 34% in 2020 to 40% in 2022 (through July), there are still 17.5 million Mozambicans without access to electricity in both rural and urban areas. Only 4.5% of the rural population had access to electricity in 2020, compared to 75% of the urban population. Given this scenario, the interest in photovoltaic systems is growing, driven by the reduced costs of solar cells and the growing environmental concerns associated with traditional forms of energy generation. In this context, the present work aims to conduct a Technical Feasibility Study for the implementation of a 10 MW grid- connected photovoltaic plant in the village of Lindela. The study is based on the knowledge acquired during the Electrical Engineering course at UEM and on the learning obtained during the professional internship at Deloitte, in the consulting department. To support the work, sources were used, such as specialized bibliography, magazines, articles, internet, manufacturers' websites, catalogs, as well as occasional consultations with supervisors, consultants, and specialists in the area. The documental analysis was complemented by the use of simulation software, such as PVsyst, Homer, Atlas Solar, and others. The work is composed of four chapters: introduction, literature review, descriptive memory, and discussion. It presents a feasibility analysis for the installation of the photovoltaic plant, taking into consideration parameters such as local irradiation, temperature, availability of the grid and electrical substation, logistical infrastructure, characteristics of the existing grid and the interconnection capacity of the plant.
