Pricing strategy of transmission network wheeling cost considering short-term operational cost

Abstract

A pricing model based on the long-term incremental cost method is proposed for calculating the wheeling cost of transmission network, which considers the influence of short-term operational cost on the investment time of transmission network components and the wheeling cost of transmission network. To simplify the analysis, the short-term operational cost considered is mainly the congestion management cost. The proposed model is applied respectively to the dual-bus test system and IEEE 30-bus test system, and compared with the traditional pricing model, which verifies its effectiveness.
