DC-OPF based allocation of wheeling prices for varying contribution of producers and customers

Due to world wide restructuring of electric supply industry, assessment and allocation of wheeling prices among transmission users has become a crucial task. Wheeling prices are supposed to be distributed over transmission users. Allocation of wheeling prices means determination of distribution of wheeling prices among transmission users and this depends upon the contribution of each user in total transmission investment cost. The contribution of transmission user in total transmission cost is decided either by transmission owner or by Regulatory body. In real world scenario, the contribution of producers and customers in cost, may be variable because it depends upon the demand supply relation. This paper presents a new approach of wheeling price allocation among transmission users by applying different level of contribution of each transmission user in total transmission investment. This enables the allocation of wheeling prices for any amount of contribution of generator and load in transmission investment. The proposed approach has been illustrated on Garver's 6-bus test system and IEEE RTS 24-bus system. This has been observed that the perspective presented in this paper is capable of recovering fixed transmission cost for varying amount of contribution of transmission users.
