Parameter Sensitivity Analysis of the Combined Cooling Heating and Power System

Abstract

The Combination of Cooling Heating and Power System (CCHP) system has become an important way of raising the system efficiency by cascade utilization. Aiming at the impacts of the parameter on the CCHP system performance, a parameter sensitivity analysis method is studied. Firstly, the energy flow is analyzed with a typical CCHP system model. Secondly, the evaluation criteria are proposed. Furthermore, the sensitivity of the parameters such as capacity, technology, economy and emission under basic operation modes are ana-lyzed to estimate potential impacts of each parameter. According to the simulation, the proposed method shows the impacts of different parameters on CCHP system performance under different modes to instruct parameter designing.
