Optimal operation of a micro-combined cooling, heating and power system

A kind of micro-combined cooling, heating and power (CCHP) system with a core of gas engine and adsorption chiller was analyzed from the optimal operation point of view. By taking the minimal operation cost meeting the load demand of cooling, heating and power as optimizing function, the economic optimization model of the micro-CCHP system was established. The specific optimum operational strategy of the system was obtained with real projects, and it was explored that the micro-CCHP system has the assurance of economic benefits. The study results indicate that the optimal operation mode is associated with energy price. Under identical natural gas price, the higher the electrical price, the better the micro-CCHP system's economic feature is.
