A systematic procedure for analysis and design of energy systems

Monograph Article dissertation (summary + original articles) Department Laboratory Field of research Opponent(s) Supervisor (Instructor) Abstract X The new re-regulated markets for electricity, stricter environmental policies and regulations, especially regarding greenhouse gases, form a new operating environment for energy systems. The new environment requires systems that are cost-efficient and have more efficient utilisation of energy with a low negative environmental impact. This can only be achieved with efficient tools for analysing and designing current and future energy systems. The objective of this work is to present a systematic procedure for analysis and design of energy systems. The procedure utilises simulation modelling, experimental design and regression models and mathematical programming. The procedure is able to simplify large problems so that they can be efficiently solved, but still preserve sufficient amount of details so that the objective of the analysis or design can be fulfilled. The main advantage of the methodology is that it can reduce the size of the problems in a way that is more flexible than existing methodologies using mathematical programming. This is important, since it can efficiently reduce the complexity of the problem, and can thus be used to analyse and design complex energy systems with respect to several objectives. In this respect the procedure can be seen as a valuable addition to the existing methodologies. My warmest thanks to all my colleagues, who have made our workplace such a nice place to work. Finally, my sincere thanks to my supervisor, professor Carl-Johan Fogelholm for giving me the opportunity to work in such a good environment and for giving me the opportunity to write this dissertation.
