Deregulation of the electricity industry throughout the world aims at creating a competitive market to trade electricity, which generates a host of new technical challenges to market participants and power system researchers. For transmission systems, it requires non-discriminatory open access to transmission resources [1]. Therefore, for better transmission services support and full utilisation of transmission assets, one of the major challenges is to accurately gauge the transfer capability remaining in the system for further transactions, which is termed Available Transfer Capability (ATC) [2]. It is crucial to develop an appropriate ATC determination methodology that enables one to evaluate the realistic transmission transfer capability by accounting for all related important requirements. To address this issue, an optimal power flow (OPF) based stochastic model is presented in this chapter for ATC evaluation, with respect to the major uncertainties in power systems associated with ATC level.
