英文摘要： Distributed CCHP systems with its energy saving and environmental protection has become one of the preferred technology of China's energy-saving emission reduction. However, the existing CCHP systems have poor matching performance of various subsystems, and it often run at off-design, so the annual thermal performance and economic of systems become deterioration. The off-design characteristic will be investigated in this project. Multi-objective evaluation criteria will be established including thermal performance, CO2 emissions and economy. We will explore the association between parameters and the targets. According to various subsystems coupling modes, dynamic load characteristic，environment and so on, the off-design performance of CCHP systems will be optimized, such as structural configuration, operation strategies. The Grey Relational Analysis will be adopted to find out the key factors infecting the off-design performance of CCHP systems. The optimal operation modes will investigate using Analytic Hierarchy Process. Using active solution energy storage modes, we will explore regulation mechanism of CCHP systems. It can ensure energy supply balance and regulate performance. The comprehensive energy cascade utilization will be achieved.
