摘要 中国清洁能源集中在西部、北部,当地用电负荷小,难以就地消纳,需要在全国范围优化配置。从新能源特性的角度研究中国西部地区风能、太阳能、水能等不同种类清洁能源的互补特性,进而研究多能互补在缓解新能源发电间歇性、随机性、波动性方面的效益,提出一种考虑网络约束与新能源随机特性的时序运行模拟技术,并对中国西部新能源大规模开发情景进行生产运行模拟计算。研究结果表明:建设西北与西南联网通道,可以实现多能互补,改善新能源外送电力品质,提高清洁能源外送通道利用效率。 The environmental problem caused by fossil energy consumption is increasingly prominent.To replace the fossil energy with clean energy is the inevitable requirement of ecological civilization construction.The clean energy in China is mainly concentrated in the north and western regions,where the clean energy is difficult to be consumed locally due to the low electricity demand,and it is necessary to optimize the energy allocation in the whole country.Based on an analysis of the supplementary characteristics of wind,photovoltaic and hydro power in China's western region in view of the renewable energy features,this paper studies the benefits of multi-energy coordination to reduce the intermittency,randomness and fluctuation of renewable energy.A sequential power system operation simulation technique is proposed considering the network constraints and the random characteristics of renewable energy sources.A simulation is made on the large scale development scenario of clean energy in northwest China,and the results show that construction of interconnection transmission channels between northwest and southwest regions can realize multi-energy coordination,improve clean energy power quality,and raise the utilization efficiency of clean energy transmission lines.
