摘　　要：提出了一种通过需求侧管理激励负荷侧的高载能企业参与调峰,提高系统风电消纳能力的错峰峰谷分时电价机制。考虑了高载能企业转移负荷能力差的特点及其对峰谷分时电价时段连续划分的诉求,建立了相应的峰谷时段连续划分的错峰用电模型,并以提高系统谷时风电消纳能力为目标建立了错峰峰谷电价决策模型。通过解耦时段划分与电价优化,设计了2步优化方法求解峰谷时段与电价综合优化模型。错峰峰谷电价避免了传统多峰时段峰谷电价对用户的频繁扰动,更加适合高载能企业等大用户的生产特点。通过协调各用户的峰谷时段划分,减少峰时段时长,减轻了高载能企业电力成本压力,提高了参与调峰的积极性。A stagger peak-valley time-of-use （TOU） price mechanism, in which heavy energy-consuming enterprises are impelled to participate the peak load regulation under the demand side management （DSM）, is proposed to improve the wind power accommodation capability of power grid. Considering the poor load transferring capability of heavy energy-consuming enterprises as well as their appeal to continually dividing the period of peak-valley TOU price, an stagger peak power consumption model with continuous division of peak-valley period is correspondingly established, and taking the improvement of wind power accommodation ability of power grid at valley period as the objective, a decision-making model for stagger peak-valley TOU price is built. Through decoupfing time period division optimization and electricity price optimization, a two-step optimization method is designed to solve the synthetic optimization model of peak-valley period and electricity price. The frequent disturbance to power consumers due to the peak-valley price under traditional multi-peak load periods can be avoided by stagger peak-valley price mechanism, so it is more suitable for the production characteristics of big consumers such as heavy energy-consuming enterprises and so on. By means of coordinating the peak-load period division of various consumers and decreasing the length of peak-load period, the stress of heavy energy-consuming enterprises due to electric power cost can be relieved, thus the initiative of heavy energy-consuming enterprises to take part in the peak load regulation is enhanced.
