The tradeoff between two different objective functions such as net present value and primary energy savings or emission reduction is presented in Pareto front diagrams. The result of the simulation and optimization gives several possible equipment size combinations. The model was tested by evaluating the study case. Next, a model was developed using the software Trnsys for the simulation and Matlab for the optimization. Moreover, a survey of the exiting feasibility analysis tools was done, and a case study was chosen and analyzed. In this project, the general context for the application of cogeneration and tri-generation projects was studied including factors which have an impact on its feasibility and performance. Nowadays, it is possible to develop software tools which use simulations and optimization algorithms to evaluate several options, compare them and chose the ones that give the optimum performance with respect to an objective function defined by the user. On the other hand, there are some internal barriers such as the difficulty evaluating potential energy savings, emission reduction, and economic performance of a project based on the circumstances of a specific site lack of awareness unwillingness to invest in CHP/CHCP projects and difficulty in selecting and sizing the equipment which would give the maximum benefits in terms of life cycle cost, energy savings and emission reduction. These may include economic incentives, easy and safe interconnection to the grid to export electricity and have backup if necessary, and access to the market to sell the surplus of electricity at a fair price. On one hand, there are some external barriers which have to be torn down by means of energy regulation schemes. Moreover, there is increasing concern in regards to energy security, the need to increase the energy efficiency in power generation and distribution as well as to lower the emissions from fossil fuel combustion.ĬHP/CHCP promoters and developers face difficulties when analyzing the conditions and proposing a plan of application. Some of the reasons for applying CHP and CHCP are: the techniques are well understood, their application could generate some profit, and the required technology is available.
One could say that the circumstances for using these techniques are better now than ever. 2012 (English) Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE credits Student thesis Abstract ĭespite the fact that cogeneration (CHP) and tri-generation (CHCP) are among the most efficient ways to produce electricity and thermal energy, there is still some unexploited potential for these techniques.
