Abstract: In example embodiments, there is provided enhanced disturbance management for an electrical power system. An enhanced disturbance management component can be operable to read monitoring data based on power flow measurements associated with measurement devices connected to an electrical power system, wherein the monitoring data can comprise alarm data indicative of an electrical disturbance within the electrical power system, and topology data indicative of a topology of the electrical power system. The enhanced disturbance management component can be operable to correlating the alarm data with a change in the topology data.

Abstract: Energy flow in a power grid system (e.g., an electrical energy distribution system) is managed. In an example embodiment, a system provides for generating monitoring data for an electrical energy distribution system based on power-flow data for the electrical energy distribution system and topology data for the electrical energy distribution system. The power-flow data is indicative of voltage values that are repeatedly obtained from the electrical energy distribution system. The topology data is indicative of a topology for the electrical energy distribution system. The system also provides for identifying, based on the monitoring data, a change in a voltage angle associated with a transmission line in the electrical energy distribution system. Furthermore, the system provides for generating a notification for a graphical user interface in response to a determination that the change in the voltage angle for the transmission line satisfies a defined criterion.

Abstract: The technology is generally directed towards real-time power grid island detection and monitoring, including obtaining and outputting information about the cause and location of the islanding event, island size, island composition, phasor measurement units in each island, and the overall island frequency. The technology provides for suggested island resynchronization actions such as one or more circuit breakers that can be closed by the power grid system operators to resynchronize an island with the main island/system. An application program may output the information and also assist the operators during the resynchronization process by providing real time information about the voltage difference and frequency difference across each proposed circuit breaker in the suggested restoration point. Real-time tracking of the island resynchronization actions is also described.
