Abstract

In the present open access restructured power system market, it is necessary to develop an appropriate pricing scheme that can provide useful economic information about transmission costs to market participants, such as generation companies, transmission companies and customers. The estimation and allocation of the transmission costs in the transmission pricing scheme is a challenging task for power utilities. In this thesis, different transmission cost calculation and allocation techniques corresponding to various components of the transmission costs are discussed. Transmission service costs are determined based on participants' actual usages on transmission networks using the usage-based method. Using locational marginal price (LMP) method, transmission congestion costs are calculated based on participants' usages and the differences in locational marginal prices. The usage-based method is also used to determine transmission loss costs. A comprehensive transmission pricing scheme using a power flow tracing method and LMP method is proposed, in which the transmission service costs, congestion costs and loss costs are considered and energy transaction information is provided. Case studies using different power system models are presented throughout the thesis to illustrate the application and effectiveness of the studied methods.
