区域分布式能源改变中国电力低碳发展格局

在碳减排的历史趋势下,2010年-2020年期间中国电力低碳发展的战略途径并非只有可再生能源一条.在非常规天然气和智能电网快速发展的前提下,充分发挥中国城市工业、商住、居民终端用能需求的冷、热、电、汽负荷可以集成供应,并与电网调峰相结合的国情特点,在系统技术和运作机制2方面集成创新,到2015年/2020年有可能与快速发展工业园区和新城区同步,建设一大批天然气分布式冷热电联供能源系统（DES/CCHP）,总装机容量达到110/220 GW,发电量达到0.5/1万亿kW h/a;2020年占总发电量14%,达到美国2010年的水平.这样,不仅能够基本解决电网昼夜调峰问题,节省数千亿元电力、电网和煤炭开发建设投资,减少对煤炭的过度依赖和碳减排压力,而且可对中国工业和商住能效提高到世界平均水平作出决定性的贡献.

Regional distributed energy changing low carbon development pattern of electric power in China

In the historical trend of carbon emission reduction,the renewable energy isn＇t the only strategic way of low carbon development between 2010 and 2020.On the premise of fast development of unconventional gas and intelligent network,by giving full play to integrated supply and combining with network peak regulation characteristics of cold,heat,electricity,steam load required by energy utilization terminals such as industry,commercial and residents,the system technology and operation mechanism are integrated innovated.By 2015/2020,a batch of natural gas distributed cooling,heating and power generation energy system are built synchronously with the new industry parks,the total installed capacity should be 110/220GW,the generated energy is 500/1,000 billion kwh;the generated energy is 14 percent of the total generation energy in 2020,reaching the level of the United States in 2010.The diurnal peak regulation problem is solved.The investment of electric power,network and coal development is reduced.The excessively dependent on coal and the pressure of carbon emission reduction are decreased.It makes decisive contributions to raising the energy efficiency of industry,commerce and living to word average.
