Abstract(in Japanese) (See Japanese page)
Abstract(in English) This paper pursues to construct a theoretical framework which can efficiently capture the dynamics of large-scale heterogeneous power grids. As a mathematical abstraction of such grids, we formulate a networked nonlinear descriptor system consisting of subsystems as a descriptor system, and network system. This descriptor representation of the system enables us to consider efficient analysis and control of the system while preserving its network topology. As a main result, we derive a sufficient condition for local asymptotic stability of partial states and synchronization based on the dissipativity of the subsystems and passivity of the network system. We apply the result to a power grid described by a structure-preserving model, showing their effectiveness in an engineeringproblem.
