State estimation is a digital processing scheme which provides a real-time data base for many of the central control and dispatch functions in a power system. Conventional State Estimation In conventional state estimation, network real-time modelling is decomposed into: i) the processing of logical data (the statuses of switching devices) and ii) the processing of analog data (e.g., power flow, power injection, and voltage magnitude measurements). Scope. Abstract and Figures. Before getting into the project engineering phase, power system planning with the focus on basic design aspects of main power system components must be performed.
