The PROMENTHEE II method is employed to evaluate five combined cooling, heat and power (CCHP) system systems using four aspects such as technology, economy, environment, and society. The CCHP systems with dynamical sources respectively are gas engine, gas turbine, Stiring engine, solid oxide fuel cell (SOFC) and a separate plant. The prime of the multi criteria evaluation method is the selection of preference function and calculation of the net flow. The criterion with linear preference function is applied to compare the five systems. The result shows that the SOFC mode is the optimal scheme in terms of the net flow. To verify the robustness of the PROMENTHEE II, the sensitivity analysis is done by exchanging the criteria weight. The result shows that PROMENTHEE II method is practical and convenient and it can provide a reliable evaluation result for CCHP systems.
