摘　　要：针对云南省某地区大用户从供电公司购电的现状,提出为大用户提供合同和实时市场两种购买渠道,并分别确定了最优电价。合同采用分类丰枯-峰谷电价的形式,将大用户按不同需求价格弹性进行分类,建立多目标数学规划模型确定各类用户的丰枯-峰谷电价比。实时市场用于平衡大用户实际用电量与合同分解电量的差值,建立基于条件风险价值(conditional value at risk)最小为目标的数学模型。分析供电公司的策略对大用户购电成本的影响。最后仿真验证两个模型的合理性,并证明此模式可以解决目前大用户购电中存在的部分问题。It is proposed that contract and spot market can be provided for large consumers to purchase power under the present environments of large consumers purchasing electric power from the power supply company in some area in Yunnan, and the optimal prices are determined. The classified season-of-use and time-of-use price is adopted in contracts. Large consumers are classified by different demand-price elasticity. A multi-objective programming model is established to determine the prices of various kinds of large consumers. The difference between planned and actual consumption power is balanced by two spot markets. A mathematical model is established on minimized CVaR（conditional value at risk） as the objective function. The purchasing cost of large consumers is analyzed. At last, simulation verifies the rationality of the models, which solves a part of problems of selling electricity to large consumers by the supply utility.
