Energy efficiency analysis of distributed multi-energy system

In order to analyse the relationship between the energy efficiency level and influencing factors, proposes a universal comprehensive efficiency formula for multi-energy system. The results show that energy conversion technical level, local renewable energy resource and system configuration are the key factors which can influence the energy efficiency. Then with the case study, illustrates the way to optimize multi-energy system design through energy efficiency analysis and proposes the energy efficiency levels of several typical configurations.
