|Abstract(s):||The use of Combined Heat and Power (CHP) technologies is increasing due to the liberalization onf energy market, energy efficiency concerns and the emphasis o distributed power generation systems. The main objective of the present work is to implement an analysis that will lead to the optimal design of a small cogeneration system, given the thermal power duration curve of a multi-family residential building. A nonlinear optimization model was implemented in MatLab environment using two distinct optimization methods: the Box and the SQP method. The optimal solution for the small CHP presented a positive annual worth and disclosed reasonable values for the decision variables of the thermo-economic model. The results were identical for both methods, demonstrating the validity of the implemented approach.|
