Power Flow Design to Enhance Damping Performance of Power Systems

Abstract

In this paper, we address a problem of enhancing damping performance of power systems. The performance enhancement is achieved by controlling the power flow and by supplementarily adding controllers. The power flow control problem is formulated as parameter design in the parameter-dependent power system model. We propose an iterative approach of linear matrix inequalities to solve the parameter design problem. Furthermore, in order to improve damping performance of the power system, controller design is combined with the parameter design.
