Abstract
There is provided an available transfer capability calculating system for operating an electric power system, calculating optimal power flow with respect to assumption failure occurring in the electric power system and calculating available transfer capability of the electric power system based on the calculated value of the optimal power flow. The system has an optimal power flow calculating processor for deriving data associated with the initial phase angle and maximum electric power value of a generator by calculating mechanical output and electrical output of a generator including a generator phase angle defined by a time function in a condition that the generator phase angle does not exceed a preset value.
