Abstract

PJM Interconnection has successfully designed and implemented a Transient Stability Analysis & Control (TSA&C) system. This is the first on-line transient stability analysis ever performed in the control center of a large power network. TEPCO-BCU was selected as a leading fast screening tool to improve the performance of PJM's TSA system. This paper will present an evaluation of TEPCO-BCU in a real time environment as a transient stability analysis screening tool. This evaluation represents the largest practical application of the theory of a stability region in terms of the system size (14,000-bus), the number of contingencies (a total of 5,293,691 contingencies), and over a wide range of operating conditions. This extensive numerical study reveals that TEPCO-BCU is an effective tool for performing on-line dynamic contingency screening of large-scale power systems.
