Resumo(s)
A otimização operacional dos sistemas de abastecimento de água (SAA) é um tema com
grande interesse, não só a nível ambiental de forma a que seja reduzido o número de recursos
naturais a utilizar, mas também do ponto de vista económico de forma a reduzir os custos
associados a esse processo. A minimização do consumo de energia elétrica e por sua vez do
custo associado é um dos objetivos principais para a otimização dos SAA, sendo que as estações
de bombagem de água têm o maior consumo nestes sistemas.
Este trabalho propõe uma metodologia que permite otimizar as regras de controlo dos
ciclos de bombagem em Estações Elevatórias (EE) que tenham sistemas SCADA, onde a flexibilidade
energética é explorada de forma a atingir determinados objetivos. A metodologia foi
aplicada a um caso de estudo referente a um SAA real de forma a reduzir os custos e as emissões
de CO2 associadas ao consumo de energia elétrica. Como conclusão após as simulações
realizadas, a utilização desta solução conduziu a uma redução média dos custos de energia
elétrica e das emissões de dióxido de carbono de 10% e 3,4%, respetivamente.
A Water Pumping and Storage Systems (WPSS) operation optimization is a theme of great interest, not only as an environmental issue related to the reduction of the number of natural resources used, but also as an economic one associated to the reduction of process costs. Minimizing the electricity consumption and the associated costs of the pumping systems is one of the main objectives for optimizing the WPSS, since the water pumping stations have the highest consumption in these systems. This work proposes a methodology to optimize the control rules of pumping stations cycles that use integrated SCADA systems, where the energy flexibility is explored to achieve certain goals. This methodology was used in a case study based on a real WPSS with the objective of reducing operation costs and carbon dioxide emissions associated with electrical energy consumption. Collected results show that the proposed solution can reduce the average electric energy costs and carbon dioxide emissions by 10% and 3,4%, respectively.
