摘要：
This paper studies iterative distributed algorithms for on-line voltage stability assessment (VSA) in energy management systems of modern smart power grids. Since VSA can be modelled as a special non-linear optimal power flow (OPF) problem, iterative decomposition-coordination approaches based on constrained augmented Lagrangian methods can be applied. The distributed scheme of Auxiliary Problem Principle Method (APPM) is investigated. A computation framework of this distributed algorithm is studied. The system partition with non-overlapping and boundary sub-systems is also investigated. Simulations on IEEE-57 bus and IEEE-118 bus systems have been tested to validate the feasibility and correctness of the distributed VSA.
