Planejamento eletroenergético da Guiné-Bissau

Abstract

From an economic, industrial, and social perspective, access to electricity is crucial for the development of any country, state, or region. This dissertation aims to conduct an electro-energy planning for Guinea-Bissau by leveraging the potential benefits of the OMVG project, which aims to integrate the power system with the energy system for green hydrogen production. The goal is to expand the energy load and reduce the population's difficulty in accessing electricity. Electro-energy planning is a strategic portfolio for each country, which includes its entire energy system and electrical matrix. The OMVG system comprises of 17 substations (nodes), two generation points, 15 load points, and an additional node from a photovoltaic plant dedicated to the P2G2P (Power to Gas) process. The total number of nodes analyzed in this study is 18. Three load levels were simulated for the OMVG network: heavy, medium, and light. These load levels were grouped into two reliability assessments: a static contingency analysis (steady-state) and a dynamic analysis (time domain). These analyses adhere to the N-1 security criteria, which allows for the loss of one network element without load shedding or damage to other equipment. These evaluations identified critical and non-critical conditions in the network's lines and nodes by observing voltage and frequency behaviors during contingencies. These conditions were identified by observing voltage and frequency behaviors during contingencies. Guinea-Bissau possesses a total of five nodes, including one from a photovoltaic plant that is connected to the Bissau substation. The OMVG provided the country with external generation capacity, allowing the creation of internal load through the integration of its energy system via transmission lines. The transmission system aims to distribute the energy generated at the plant and transport it to distribution centers in order to meet the final consumer demand. It is anticipated that through the OMVG, Guinea-Bissau will be able to resolve its electricity access issues. P2G2P plays a critical role in the production and storage of green hydrogen for energy purposes. The six islands designated for P2G2P will receive 90 kilograms of daily green hydrogen production for their supply, thus serving a region of significant economic and tourist significance.
