摘　　要：在考虑了用户需求弹性、现货市场和合同市场的购电成本以及对用户的补偿等因素的基础上,建立了分时电价体制下供电企业购售电风险控制模型。采用该优化模型可使供电公司制定出使企业效益和社会效益均得到提高的分时电价,并能有效地进行削峰填谷,使供电公司承担最小的风险并获得最大的利润。算例仿真结果表明了该模型的有效性。On the basis of considering such factors as customer demand elasticity, power purchasing costs in spot market and contract market and the compensation for customers, a risk control model Of power purchasing and selling for power supply company under Time-of-use （TOU） mechanism is proposed. Adopting this model the power supply companies can draft their own TOU price, by which both social effect and power companies economic benefits can be improved, and the peak load leveling can be effectively carried out, thus the power supply companies can bear minimized risks and obtain maximized profits. Case study results show that the proposed model is efficient.
