Abstract

It is well known that continuous small power disturbances can excite the forced power oscillation in power systems, and removal of disturbance source is the best way to rapidly attenuate the oscillation. In order to find the location of disturbance source, energy conversion characteristics of the forced power oscillation in a linear system during steady-state resonance were analyzed. Considering practical application in power systems, this paper proposes an improved energy function method for disturbance source location of forced power oscillation. Case studies of two-area with four-machine benchmark system and a practical large regional power grid prove the feasibility and effectiveness of the proposed approach.
