Electric Power Research Institute, State Grid Gansu Electric Power Company, Lanzhou 730050, Gansu Province, China) ABSTRACT: 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 decoupling 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
