Abstract(s)
As relações comerciais presentes no mercado elétrico português têm sofrido várias transformações, verificando-se um afastamento ao longo dos anos da intervenção do Estado Português. A adesão de Portugal à Comunidade Económica Europeia (CEE), em 1985, possibilitou a criação de medidas que permitiram a livre concorrência dos intervenientes da produção e comercialização de energia elétrica, consubstanciando a abertura do setor, produzindo eletricidade de forma distribuída a qualquer cidadão ou empresa. (1). Atualmente, verifica-se a completa liberalização do setor, sendo possível, independentemente da potência contratada, que qualquer cliente escolha o seu fornecedor de energia. Assim, à semelhança de outros países europeus, foi criada uma figura de mercado no desígnio de facilitar as relações comerciais entre produtor e comercializador (vulgo agente de negociação). Este agente de negociação, aquando em ambiente de mercado, é conhecido como agente agregador, que minimiza custos ao comercializador e maximiza os proveitos dos produtores. O agregador terá de conhecer o perfil energético e o risco associado a cada produtor, calculando a previsão resultante da sua negociação de venda no mercado ibérico. Dito isto, a presente dissertação tem como desígnio o desenvolvimento de um sistema capaz de auxiliar a previsão da produção de energia através de fontes renováveis, cuja aplicação seja útil para a redução de desvios energéticos.
Commercial relations in the Portuguese electricity market have been subject to multiple changes, as a result of the Portuguese State's intervention since 1975. With the adhesion of Portugal to the European Economic Community (EEC) in 1985, it led to the adoption of measures which would allow free competition of the parties involved in the production and commercialization of electricity, allowing the opening of the sector, to produce distributed electricity to any citizen or company. Nowadays, the sector is completely liberated, being possible, regardless of the hired power, any customer to choose its energy supplier. Thus, like other European countries, a market figure was created with the objective of facilitating the commercial relations between producer and marketer (commonly known as the trading agent). This trading agent in a market environment is known as an aggregating agent, which minimizes costs to the marketer and maximizes the profits of the producers. The aggregator will have to know the energy profile and the risk associated with each producer, calculating its forecast that results in its negotiation of the sale in the Iberian market. The present dissertation intends to develop a system capable of assisting the prediction of the production of energy through renewable sources, the application of which can be useful for the reduction of energy losses.
