smart grid consumption shifting mechanism design equilibrium incentive compatibility budget balance continuous function
In order to maintain the balance between the supply and demand of electric power in every period of time,this paper formally describes the problem of electric power consumption shifting within two different time intervals of the peak and the bottom,and then presents a directly applicable electric power consumption shifting scheme with three-tier architecture.Users participating in the scheme,however,can get extra rewards through shifting certain power consumption quantity from the peak to the bottom time intervals.In addition,taking into account the fact that individual shifting costs vary with the different geographic areas,this scheme firstly allocates rewards to agencies in different geographic areas in the way of equilibrium.A strictly proper rule is proposed to reward contributors according to the efficiency,which achieves the theoretical properties including equilibrium,individual rationality,budget balance and incentive compatibility.The experimental results indicate that the proposed scheme not only smoothly completes the electric power consumption shifting and keeps power balanced between supply and demand in every period of time,but also improves the social rewards and its stability.
