State estimation deals with the real-time measurements to obtain the best estimate of the current state of the power system, based on the network connectivity, system parameters and the analog measurement as inputs. With the error minimization algorithm, state estimation algorithm provides consistent base case, used for further power system analysis.
Adequacy of the measurements is assured by observability analysis, required for successful run the state estimation.
The key features of the module are :
- Standard Weighted Least Square (WLS) method
- Bad data identification and suppression
- Observability Analysis for RTU Locations
The output of the State estimation is estimated load, generation and voltage profile along with the real and reactive power flows. This is used for carrying out power system simulation like, load flow scenarios, real and reactive power optimization and security analysis.
