Idaho National Laboratory performed research and development efforts associated with the first primary recommendation from a U.S. Department of Energy, Office of Electricity workshop—the MSE. This agent serves as an independent, authoritative, protective software module/device for every zone of protection in its area of influence, monitoring the communications and power systems’ protective relays for anomalous conditions or misoperations. The benefits of these metrics are that they provide an assessment, from the ground up, of the grid state at lower latency and with greater resilience to threats; they also provide early indications of impact from damaging storms and cyberattacks.
