摘要
大规模新能源并网后,对电网形成巨大的冲击,随之出现诸多问题,如弃风弃光电量不断增长、调峰缺口不断增大,对电网的安全稳定形成隐患,同时也形成一种资源浪费。面对这些问题,尝试从高载能企业出发,建立大规模新能源并网后高载能用户参与调峰的分析模型,包括调峰需求能力评估模型、调峰能力评估模型、调峰缺口计算方法、高载能调峰分析模型,并针对甘肃典型高载能企业进行实例计算和分析。基于综合集成平台,采用组件搭建方式构建了大规模新能源并网后高载能用户参与调峰的仿真系统,对高载能调峰结果进行仿真,结果表明,高载能具有很大的调峰能力,通过引入高载能进行调峰,可以很大程度上增加电网对新能源的消纳能力,为高载能消纳新能源提供了前期探索经验。
Large-scale new ener gy integration for ms the huge impact for power grid, and many problems eme r-ges, such as powe r of dics arding wind and lighti ncreasing, the peak shaiv ng gap growing,t he pro blems brings r isks for grid security and stabitli y, but also forms a waste ofr esources.Face d with these pr oble ms,it attempt s to statr from the high energy enterprises to establish the peaking analysis model involve d by high energy consu-ming usersa fter the new energy integration, inlc uding the peaking need capacity assessment model, peaking assessment model, peaking gap calculation method, high energy consuming peak analysis model, and the pa-per takes the Gansu typical high energy consuming enterprises examples to calculate and analyze.Based on the comprehensive integr ation platform, using component to build the simulation system participated byh igh en-ergy consuming users atfe r then ew energy integration, so as tos imulate th e peaking result.The results hows that high e nergy has great peaking capaic ty, and itl argely increases the grid absorbability for new energy through the introduction of high energy consuming to peak, meanwhile it provides a preliminary exploration ex-perience for high energy consuming absorbing new energy.
