State Estimation

This use case is an alternative and expansion of the SCADA Data Update use case. It separates the Power System State Model between three subsystems: Data Acquisition, Topology Processor and State Estimator. The State estimation application fetches data values from SCADA operations model, processes topology, estimates a new state, detects bad measurements and returns estimated states to SCADA operations model. It also makes a copy of the network state available for other network analysis applications.
