Abstract: With the rapidly growing demands for power, the task to make users' demand adaptive to power supply is attracting more and more attention. In this paper, we present a novel model of power consumption shifting with continuous market price function instead of the common stepwise piecewise function, and then an applicable shifting scheme with three-tier architecture is designed. In order to get extra rewards, users involved in the scheme are encouraged to shift certain consumption of power from high to low demand time intervals. So, taking into account the fact that value ranges of users' shifting costs and capacities vary because of different geographic areas, grid firstly allocates rewards to power stations in different geographic areas in the way of percentage for shifting cost, and then an appropriate rule is introduced to allocate rewards to contributors according to their bids. We investigate the good economic properties including individual rationality, budget balance and incentive compatibility. At last, to verify the scheme given by this paper, an example is given to illustrate the correctness and effectiveness.
