Based on an analysis of research and development of the distributed energy system and combined cold

heat and power generation system (DES/CCHP)

this paper presents an overall integration thought and technological integration scheme for regional DES/CCHP coordinated with the power system. With the coordinated optimization of structure and function based on the integration modes of variable structures

this paper presents the integration technology scheme on several regional DES/CCHP

the multi-source energy network system and the distributed renewable energy system. In the meantime

the collaborative and supplementary operation mode is employed on the basis of the dynamic composition of the energy utilization process to provide a common integration scheme for efficient

cascade use of clean energy and large-scale application of distributed renewable energy. The integration scheme is expected to be applied in a national demonstration project in Hunan Province.
