Abstract: The renewable energy based combined cooling,heating,and power system（RE-CCHP system） is a multienergy complementary integrated energy system with comprehensive supplies of cooling,heating and power. The RECCHP is of great importance for large-scale utilization of renewable energy and protection of our environment,because it can significantly improve the energy efficiency and system reliability. This paper presents an overview of the main research progresses in the RE-CCHP system in recent years,summarizes the research results in integrated configuration,designs and operation optimization of the system, clarifies the current research status of the system and points out the essential issues to be address,and forecasts the future direction in this field.
