This paper presents a method to decompose the wheeling prices of electricity by breaking down each wheeling price into a variety of parts corresponding to the concerned factors, such as generations, transmission congestion, voltage limitations and other constraints. This obtained detail information for wheeling prices can be used not only to improve the efficient usage of power grid and congestion management, but also to provide economic signals for generation or transmission investment. Several numerical examples demonstrate the effectiveness of this approach.
