田国栋指出,根据调查,北京已建成天然气分布式能源项目均存在实际负荷与设计负荷有偏差、电力并网等关键工程技术落实不到位、技术细节设计不够完善、后期维护管理没有得到足够重视等问题。归纳北京已建成项目及开发建设过程中项目的经验和教训,可以从负荷预期、政策环境、技术实施、运营维护四个角度来分析存在的问题。负荷预期偏差问题田国栋说,针对项目具体负荷进行量体裁衣设计供能系统是分布式能源最本质的特点和要求。负荷预期偏差是 Tian Guodong pointed out that according to the survey, the distributed natural gas projects in Beijing have been deviated from the actual load and the design load, the key engineering technologies such as power grid integration are not in place, the technical details are not designed well and the maintenance and management are not paid enough attention at the later stage . Summarizing the experiences and lessons learned from the completed projects in Beijing and the projects in the process of development and construction, the existing problems can be analyzed from the perspectives of load forecast, policy environment, technical implementation and operation and maintenance. Tian Guodong said the problem of bias in expected load, tailored to the specific load of the project Design energy supply system is the most essential features and requirements of distributed energy. The expected deviation of load is
