基于不同供能模式的燃气分布式能源系统性能评价
Performance evaluation of gas-fired distributed energy system based on different energy supply modes
摘要：
针对热电分产系统、常规分布式能源系统和双源型分布式能源系统，提出了系统经济性、节能性和环境性评价指标。以上海地区办公楼、医院和宾馆3类典型建筑为例，基于“以热定电”模式确定了不同供能模式下的系统设备选型与容量配置，对比分析了双源型分布式能源系统和常规分布式能源系统的综合性能及逐时运行策略。分析结果表明，双源型分布式能源系统在经济性、节能性、环境性3个方面均有不俗表现，并且对燃气和电力调峰有积极意义。
Abstract：
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.
Keywords:energy supply mode, distributed energy system, performance evaluation, power peak regulation, gas peak regulation
