Error analysis in electric power system available transfer capability computation

A key concept in the restructuring of the electric power industry is the ab ility to accurately and rapidly quantify the capabilities of the transmissi on system. Transmission transfer capability is limited by a number of diffe rent mechanisms, including thermal, voltage, and stability constraints. Thi s paper discusses the available transfer capability (ATC) definitions and d etermination guidelines approved by the North American Electric Reliability Council (NERC) and presents several concepts for dealing with the potentia l errors and technical challenges of computation.
