On-line power system stability screening of practical power system models using TEPCO-BCU

The PJM Interconnection has successfully designed and implemented a Transient Stability Analysis & Control (TSA&C) system at the PJM system control center using new techniques. TEPCO-BCU was selected as a fast screening tool to improve the performance of the PJM TSA system. This paper presents an evaluation study of TEPCO-BCU in a real-time environment as a transient stability analysis (TSA) screening tool. This evaluation study is the largest in terms of system size for a practical application of the theory of the stability regions.
