Abstract
Power systems, such as transmission systems, may comprise a series capacitor bank (SCB) to provide series compensation on a power line. The SCB may be electrically inserted into the power line or bypassed according to commands sent by remote systems. Such commands may be compromised in a cyberattack to cause deteriorated conditions and instability in the power system. Thus, according to an embodiment, a protection layer is provided in an SCB station to intercept commands prior to execution, assess the consistency of the commands with a physical state of the power system, and either allow or block the commands based on the assessment, to thereby protect the SCB from cyberattacks.
