Performance evaluation of gas-fired distributed energy system based on different energy supply modes

Proposes the economic, energy and environmental assessment indexes for conventional centralized energy systems, conventional distributed energy systems and dual-source distributed energy systems. Taking office, hospital and hotel in Shanghai as examples, determines the equipment configurations for different energy supply modes under thermal-tracking operating mode, and compares the system performances and corresponding running strategies. The analysis results indicate that the dual-source distributed energy system has satisfied economic, energy and environmental performances, and also contributes to the power and gas peak regulations.
