Discrete and Continuous Identification Algorithms of the Power Electric System in the State Space
Discrete algorithms for identifying a linear model of the electric power system in the state space for cases of a system with one and a number of inputs, as well as with one and multiple outputs, are developed and investigated. The necessary conditions for identifiability are the a priori properties of the complete observability of the model of the system. The basis of the identification algorithms is the invariance property of the shift property of the observability matrix. The work is illustrated by a practical example of identification of a 25-machine power system.
