Abstract Converting thermal energy to electricity is one of the most common energy conversions in the field of electricity production. This transformation of energy is essential for both renewable and non-renewable heat sources. One of the main parameters of such a system that is responsible for this conversion is its efficiency. To have an efficient transformation, many improvements have been made to the old methods, and also new techniques were developed. One of these new methods that will be discussed here is a combined system of a Free Piston Stirling Engine (FPSE) with a Permanent Magnet Linear Synchronous Machine (PMLSM). The two purposes of presenting such a system are that firstly, the theoretical efficiency of a Stirling engine is high. Secondly, by eliminating crank-shaft from this system compared to the standard Stirling engine system, some of the losses will be removed. To study this system, a thermodynamic model of a RE-1000 FPSE was presented and validated. Then it was coupled with a PMLSM, and the combined system was controlled. The total efficiency of this system in steady-state is 14.4%.

Pumped Storage

A elevada intermitência das fontes de energia renováveis condiciona a produção de energia elétrica, que continua a depender muito dos combustíveis fósseis. Uma vez que existe complementaridade por parte das fontes de energia renováveis, a sua integração conjunta é, sem dúvida, a melhor solução para reduzir esta dependência. Aliado a este facto, poderá coexistir um sistema de armazenamento por bombagem, capaz de gerar reservas hídricas, que serão aproveitadas quando a procura exceder a oferta energética. Procedeu-se ao desenvolvimento de dois modelos: um sobre custos de turbomáquinas e outro que visa o estudo do potencial de recuperação de energia de uma solução energética híbrida com armazenamento por bombagem combinado com fonte de energia eólica. Foram estudadas diferentes combinações para estas duas fontes de energia renovável, analisando o consumo satisfeito e a energia eólica não consumida, tendo-se concluído que o excedente de energia eólica pode ser aproveitado para bombagem. The high intermittence of renewable energy sources determines the production of electricity, which remains highly dependent on fossil fuels. Since there is complementarity between renewable energy sources, their joint integration is a potential solution to reduce this dependency. Consequentially, a pumping storage system capable of generating water reserves can coexist, which will be used when demand exceeds the energy supply. Two models were developed: one based on turbomachinery costs and the other based on the potential of energy recovery of a hybrid energy solution with pump storage combined with wind energy. Different combinations were studied for these two sources, analysing the satisfied consumption and the wind energy that is not consumed, in which it was concluded that the surplus of wind energy can be used by pumped storage.
