A Time Division Pricing Based Economic Model to Enhance QoS and Resources Utilization of Grid Services

Abstract

Grid economics helps to build a large-scale and geographically distributed grid system as it offers incentive for resource owners to contribute their resources for others to use and profit from it. Numerous grid economic models including microeconomic and macroeconomic principles have been proposed in the recent years. However, grid users (GUs)' strategy and behaviour for utility maximization have not been reflected sufficiently in these models. A time division pricing (TDP) based economic model is proposed in this paper. The model employs a price elasticity coefficient to describe the impact of the GUs' response of grid resources demand on the grid resources price. By attracting GUs to consume grid services from peak time to off-peak time in terms of the changing of grid service price, TDP based economic model can enhance quality of service and grid resources utilization of grid services significantly.
