State Estimation Sensitivity Analysis

Within energy management systems, state estimation is a key function for building a network real-time model, which is a quasi-static mathematical representation of the current conditions in an interconnected network. The obtained model is dependent on the assumptions, and sensitivity analysis can be used to show how measurement schemes, transmission line modeling, and other parameters affect the quality of the state estimation solution. This paper provides expressions to compute all these sensitivities, and an example and a case study are used to illustrate them.
