In recent years, electric utility industry in the whole world has been facing pressure to be deregulated or restructured in order to increase its efficiency, to reduce operational costs or to give consumers more alternatives. The once centralized system planning and operation management must be remodelled to adapt to the new market environment. Subject to the unavoidable constraints, such as, capacity of generation stations, physical limitations of the transmission lines, and demand on days-ahead scheduling, the current trading mechanism needs to be revised so that any party can involve in this freemarket decor. This paper presents a multi-agent approach to resolve the multilateral trading problem. We have implemented a prototype based on Bilateral Shapley Value and Internet technologies. The prototype has been tested with a classical six-bus system.
