This paper proposes a radically new approach to estimation power systems, named the comprehensive estimation. The comprehensive estimation modifies the scope and functionality of the estimation paradigm by refusing to treat network status and impedance data as known with certainty and making them a subject to estimation. It brings into a unified formulation and solves for all key parameters of a power network: analog measurements, circuit breaker statuses, and branch impedances. The state estimation is conceptually redefined and transformed into the state and topology estimation, which combines the estimation of network state and breaker statuses into a single process and is the first component of the comprehensive estimation. The second component is the parameter estimation which recursively refines impedance parameters of network branches using a new dynamic filtering algorithm. The comprehensive estimation framework ensures that errors in analog measurements, breaker statuses and network impedances are identified and corrected thus providing an error-free estimator solution to dispatchers as well as to analytical and control applications.
