Operation strategy of interconnected combined cooling, heating, and power systems based on exergoeconomic analysis

摘要

An operation strategy of interconnected combined cooling, heating, and power (CCHP) systems is proposed. The energy production price is determined using an exergoeconomic analysis. The systems can exchange cooling, heating, and power energy with each other according to the energy price. Moreover, the energy saving ratio and operation costs are examined in a detailed analysis of the off-design performance and energy transport losses of the system. A case with three interconnected operating systems is studied, and the results show that the energy saving ratio increases by 5.9 percentage points and the operation costs decrease by 2.7% compared with those of the individual operating systems.
