Abstract(s)
Em Cabo Verde, os objetivos da iniciativa “Energia Sustentável para Todos” (SE4ALL), estão
perfeitamente alinhados com as estratégias desenvolvidas para o setor energético e com o papel
que este terá no desenvolvimento do país. Nos últimos anos a economia de Cabo Verde tem
registado um crescimento sólido, que passou a ser virada para os serviços e liderada pelo setor
do turismo.
Nesse cenário, estabeleceu-se metas para a promoção de fontes de energia renováveis (FER), a
fim de reduzir as emissões de gases com efeito de estufa e reduzir a dependência das
importações de energia.
Apesar das vantagens da integração das FER nos sistemas de energia elétrica, a sua
variabilidade e incerteza levantam questões importantes relacionadas com a operação do
sistema elétrico. Como resultado, os operadores de sistema precisam de tomar medidas para
equilibrar a geração de energia, cada vez mais volátil com a procura, de modo a garantir a
estabilidade do sistema.
Sendo, para tal, de extrema importância a escolha das tecnologias de armazenamento mais
adequadas assim como a sua localização na rede da Ilha do Sal (objeto de estudo). De modo,
que satisfaça as metas estabelecidas de utilização de energias renováveis e que os operadores
do sistema elétrico as possam integrar e operar de forma eficiente.
O investimento nas soluções de armazenamento apresentadas pelo algoritmo genético aplicado,
num critério multi-objetivo (perdas e investimento), demonstra que o correto dimensionamento
e localização de sistemas de armazenamento na rede elétrica, apresenta vantagens. Estas
vantagens estão relacionadas com o aumento da eficiência energética da rede de distribuição, a
redução dos impactos ambientais, o aumento da fiabilidade, maior aproveitamento da produção
com recurso a FER e eventualmente em investimentos evitados no reforço das redes.
ABSTRACT: In Cabo Verde, the objectives of the “Sustainable Energy for All initiative” (SE4ALL) are perfectly aligned with the strategies developed for the energy sector and with the role it will play in the country's development. In recent years, Cape Verde's economy has been growing steadily, becoming service-oriented and mainly by the tourism sector. In this scenario, targets were set for the promotion of renewable energy sources (RES) in order to reduce greenhouse gas emissions and reduce dependence on energy imports. Despite the advantages of integrating RES in power systems, their variability and uncertainty raise important questions related to the operation of the electrical system. As a result, system operators need to take action to balance ever more volatile power generation with demand, and to maintain system stability. To this end, it is extremely important to choose the most appropriate storage technologies as well as their location in the network (Ilha do Sal - object of study), so that it meets the established targets of renewable energy in the way that system operators, can make it efficient. The investment in the storage solutions presented by the applied multi-objective (losses and investment) genetic algorithm, shows that the correct sizing and location of storage technologies in the electrical network, presents good advantages. These advantages are related to the increase of the energy efficiency of the electrical systems, the reduction of the environmental impacts, the increase of the reliability, greater use of production using RES and avoided investments in the reinforcement of the networks.
