A novel grid-wide transient stability assessment and visualization method for increasing situation awareness of control room operators

The aim of the paper is to introduce a grid-wide assessment method to determine the transient stability margin and visualize it effectively to increase the situation awareness of control room operators. Critical area(s) with insufficient transient stability margin have to be identified in order to be able to take appropriate preventive actions. The introduced method evaluates the transient stability margin with a time-domain approach by using the voltage angle of several buses across the power system. Information about the severity of a contingency and the location of the most critical buses is derived. Moreover, it is shown that the method facilitates the visual examination of transient stability. It provides control room operators with essential information about the state of the system and enables them to take appropriate preventive actions if insufficient transient stability margins are detected.
