Modeling and Simulating Single Points of Failure for TPL-001-5.1 Compliance

This paper presents a practical approach to comply with the upcoming TPL-001-05.1 standard by modeling and simulating protection and planning systems in their preferred environments. Firstly, the challenges are discussed, including data gathering for a single point of failure, wide-area modeling of protection and planning systems, and co-simulation of these systems. The paper describes modeling approaches for single points of failure, simulating the operation of the protection system during contingencies and performing stability analysis accordingly. The presented approach is implemented for two North American utility networks and can be expanded to any utilities seeking compliance with the TPL-001-05.1 standard.
