Esta dissertação tem como objectivo, analisar o impacto na rede elétrica, da inclusão de um dispositivo de armazenamento de energia com capacidade de controlo de fluxo de potência (Grid Booster), como uma alternativa ao reforço de rede clássico, obtido através da construção de novas infraestruturas de energia elétrica, na ilha de Santiago, Cabo Verde. Esta necessidade decorre do elevado investimento que se prevê em novas fontes de energia renovável, e do impacto que as mesmas poderão ter na operação da rede. Para medir o impacto do Grid Booster, foi inicialmente efetuada uma caracterização da ilha de Santiago, da sua evolução esperada, de forma a desenvolver cenários operacionais, em linha com os dados reais disponibilizados pelo operador da rede. Isto permitiu efectuar um diagnostico em regime permanente, tendo em consideração critérios de planeamento e operação em vigor. Posteriormente, foram desenvolvidos cenários topológicos correspondentes a utilização do Grid Booster, o qual permite, através de armazenamento de energia, controlar o transito de energia entre dois dispositivos, tendo-se identificado locais para a sua implementação. Foi avaliada a utilização da infraestrutura existente, com reforço de linha aérea existente, e comparada com a colocação do Grid Booster na mesma localização, em regime permanente e em regime de contingência. Dos resultados obtidos, concluímos que o Grid Booster consegue evitar a construção de uma nova linha elétrica, utilizando a infraestrutura já existente. Esta conclusão e obtida, considerando uma evolução da rede com a introdução de mais duas centrais de geração de energia renovável (solar e eólica), e evolução das cargas existentes na rede.
This dissertation has as a main goal, analyze the impact in the electric network, of the connection of an energy storage device, with the capability of controlling the power flow (Grid Booster), as an alternative to classic grid reinforcement, achieved with the construction of new electric energy infrastructures, in Santiago Island, Cape Verde. This need comes from the high investment that is expected (520M€ till 2030), in new renewable energy sources, and the impact that they may have in network operation. To measure the impact of the Grid Booster connection, at first, it was made a characterization of the Santiago Island, and it’s expected evolution, in such a way that we could predict several operational scenarios, in accordance with real data, made available by the grid operator. This, allowed to perform a diagnostic in normal state, considering the current planning and operation scheme. Afterwards, we’ve developed several scenarios, corresponding to Grid Booster use, that allows, with energy storage capability, control the power flow between two devices, and, therefore, identifying locations in the network for its installation. The usage of the existing infrastructure, with overhead line reinforcement, was evaluated and compared with the installation of the Grid Booster, in the same locations, for normal and contingency states. Of the results obtained, we agreed that the use of the Grid Booster can avoid the traditional solution, this meaning, that can avoid the construction of a new overhead line, using the existent infrastructure. This conclusion it’s achieved, considering a network grid evolution, with the connection of two new renewable energy production plants (solar and wind power), and existing loads evolution.
