Abstract: An intelligent electronic device (IED) includes memory and a processor operatively coupled to the memory. The processor is configured to establish, over a communication network of a power system, a connection association (CA) with a receiving device using a MACsec Key Agreement (MKA). The processor is configured to automatically send an announce message indicating a set of enabled application protocols on the IED to the receiving device.

Abstract: The present disclosure pertains to distributed controllers configured to control a plurality of electrical generators in an electrical generation and distribution system. In one embodiment, a distributed controller consistent with the present disclosure may include a communication subsystem configured to communicate via a network. The communication system may receive a first plurality of time-stamped electrical parameter measurements associated with a first electrical generator. A measurement analysis subsystem may detect a change caused by an event in the measurements associated with the first electrical generator, and may detect a change in a second plurality of time-stamped electrical parameter measurements associated with a second electrical generator. A magnitude of the event may be determined based on the first and second plurality of time-stamped electrical parameter measurements. A load sharing dispatch subsystem may adjust an electrical output of the second electrical generator based on the magnitude of the event.

Abstract: A software defined network (SDN) switch of a communication network includes a memory and a processor operatively coupled to the memory. The SDN switch receives a media access control security (MACsec) frame of power system data. The SDN switch detects an SDN flow match based at least in part on a port identifier of the MACsec frame. The SDN switch performs an action based on the SDN flow match.

Abstract: The present disclosure pertains to distributed controllers configured to control a plurality of electrical generators in an electrical generation and distribution system. In one embodiment, a distributed controller consistent with the present disclosure may include a communication subsystem to obtain a first plurality of time-stamped electrical parameter measurements from a first node. A measurement analysis subsystem may compare the first plurality of time-stamped electrical parameter measurements and the second plurality of time-stamped electrical parameter measurements. The first node and the second node may be associated in an electrical island by a topology detection subsystem based on the correlation. A control subsystem may be configured to implement a control action based on the association of the first node and the second node in the electrical island.
