Abstract(s)
Na presente dissertação é realizada a modelização do Sistema de Transmissão Nacional
(STN) da Colômbia, a sua análise e diagnóstico em regime permanente bem como em
regime de contingência n-1.
Para o efeito foram desenvolvidos quatro cenários típicos de operação da rede atendendo
à hidraulicidade (seco ou húmido), às tecnologias de geração, térmica ou hídrica, e
também aos níveis de consumo (ponta ou vazio).
Para cada um dos cenários, avaliaram-se os perfis de tensão bem como a taxa de ocupação
dos elementos da rede, nomeadamente linhas e transformadores, tendo-se realizado um
diagnóstico da rede cujos resultados obtidos estão em linha com o reportado em relatórios
técnicos das entidades responsáveis pela operação e planeamento do STN.
Por fim, foi estudada a capacidade de integração de energias renováveis na rede, tendo
como área de estudo a subárea operativa Guajira-César-Magdalena (GCM), situada a
nordeste e caracterizada por um elevado potencial de energias renováveis, considerando
o modelo da rede desenvolvido anteriormente bem como os quatro cenários de geração e
consumo.
Para o efeito foi realizado um estudo da capacidade máxima de integração de renováveis
através de dois métodos de compensação:
i. Método de compensação do Slack Bus;
ii. Método de compensação da Ordem de Mérito.
Este estudo visou identificar as subestações que tem capacidade de receber geração bem
como obter os respetivos valores máximos de injeção permitidos, sem comprometer a
operação da rede.
In the present thesis is carried out the modeling of the National Transmission System (STN) of Colombia, its analysis and diagnosis in steady-state as well as outage contingency (n-1) criterion. For this purpose, four typical scenarios of the operation of the network were developed, considering the hydraulicity (dry or wet), generation technologies, thermal or hydro, as well as the demand levels (peak or off-peak). For each one of the scenarios, the voltage profiles were evaluated as well as the loading levels of the network elements, namely lines and transformers, and a network diagnosis was performed of which results obtained are in line with the reported in the technical documents of the entities responsible for the operation and planning of the STN. Finally, the capacity of integrating renewable energies in the network was studied, having as study area the operational subarea Guajira-César-Magdalena (GCM), located in the northeast and characterized by a high potential of renewable energies, considering the network model previously modelized as well as the four scenarios of generation and demand. For this purpose, a study of the maximum integration capacity of renewables was carried out through two compensation methods: i. Slack Bus compensation method; ii. Merit Order List compensation method. This study aimed to identify the substations that are capable of receive generation as their maximum permissible injection values, without compromising the operation of the network.
