中文摘要：
近几年，风电消纳成为中国风电大规模发展的主要瓶颈。风电具有昼少夜多、与用电负荷反调峰的特征，引入峰谷分时电价（TOU）能够调整用户削峰填谷，增加风电消纳。在当前节能发电调度的政策背景下，以发电燃煤成本与机组启停成本最小为目标，构建了用户峰谷分时电价下的风火电联合调度优化模型。算例分析显示，与TOU前风火电联合调度优化模型相比，构建的模型能够有效降低发电燃煤消耗量，增加风电上网发电量。
英文摘要：
In recent years, wind power digestion has become a major bottleneck in wind power large-scale development. Wind power has characteristics of ltitle in day, much in night and anti-eleetrieily lag. Introduction of time-of-use （TOU） price to adjust the users＇ load can digest wind power effctively. Therefore, wind/thermal power joint-ran optimization ,nodel is constructed based on TOU price under the background of the energy-saving generation dispatching way and the target of minimizing the cost of coal-fired cost and unit commitment. With the numerical example, it is found that the TOU price can realize the goal of peak load shifting, increasing wind-connect amount and reducing the system＇s coal consumption compared with the resuh before the implementation of TOU price.
