In this paper, the structure and control tasks are briefly summarized for ORC (Organic Rankine Cycle) based WHECSs (waste heat energy conversion systems). A control-oriented physical model is established for WHECSs. The energy conversion efficiency of ORC systems is investigated. A constrained...

The electricity to thermal energy output ratio is an important impact factor for the operating modes and performances of combined cooling, heating and power (CCHP) systems. If the energy requirements of users are managed to just match this ration, the system efficiency would reach the maximum....
