【Abstract】 Distributed energy systems( DES),which are typically composed of a number of modular and small scale technologies and situated close to the end users,can be regarded as an essential complement to conventional centralized power network. They make contributions for renewable energy promotion,energy conservation,energy structure optimization and emission reduction. Based on the research achievement of authors’ group,this paper has summarized the system concept and development status; technological features,key technologies associated with both system integration and key processes; key scientific issues including system performance evaluation,mechanism of multiple energy complementation and their cascade conversion,off-design operation strategies.更多还原
