A sensitivity -based approach for static and dynamic load parameter estimation

In this paper a parameter estimation, based on sensitivity theory, has been applied to power system in order to evaluate static and dynamic load equivalents. Such equivalents are represented by a single induction motor that equivalence all dynamic load and a voltage dependent static load. The developed procedure can be implemented in on-line allowing a self-adaptive identification. Test results demonstrates the goodness and the practical applicability of the proposed procedure.
