STATE ESTIMATOR
State estimation for large distribution networks
Real-time measurements are increasingly available within electrical distribution networks. However, this data is not always perfect it may be incomplete or contain errors.
The State Estimator uses advanced statistical techniques to calculate actual values from imperfect data. This enables the approximation of unknown values and the filtering of errors, providing a reliable view of the current state of the network.
Applications of the state estimator
The results generated by the state estimator are used across various strategic areas:
Load flow analysis
With corrected and reliable values, load flow analysis becomes more accurate, enabling optimal management of energy resources.
Visualization for operators
The estimator provides an accurate graphical representation of the network, helping operators detect anomalies.
Generator dispatch
Estimator data allows for efficient generator dispatch, ensuring a balance between supply and demand.
Contingency analysis
Failure scenarios and critical situations are evaluated using accurate information to anticipate and mitigate network risks.
Network planning
Corrected state estimator data serves as a basis for designing and planning distribution network expansions and improvements.
Importance of state estimation
The ability to rely on a trustworthy network model based on corrected measurements and calculated data is essential for operation and decision-making.
The state estimator is a key tool for improving the efficiency, safety, and stability of large distribution networks.
