This paper presents a robust MIMO centralized fixed order wide area damping controller to damp inter-area oscillation in power system. The proposed H∞ approach is robust with respect to multi-model uncertainty, fixed and propagated time delay. Multi-model uncertainty comes from different system operating points and varying grid topologies. Wide-area controls have communication links, which cause time delay uncertainty. This Hoo controller is based on loop shaping. Loop shaping is a frequency domain technique for enforcing requirements on control bandwidth, response speed and steady state error. Despite other type of robust controller, this fixed order method can be applied to entire system as well as reduced order model. Moreover, the degree of controller is defined by the user. The controller is designed by using convex optimization to minimize the difference between real and desired open loop transfer functions. The method is applied to a two-areas, four machines system under different load conditions, including changing system topology, uncertain time delay, etc. |
