Robust Centralized Fixed Order Wide Area Damping Controller for wind integrated power system

摘要

This paper presents a robust MIMO centralized fixed order wide area damping controller with reserve input/output control signals to damp inter-area oscillation for wind integrated power system. The proposed approach is robust with respect to multi-model uncertainty, fixed and propagated time delay. Multi-model uncertainty in wind integrated power system comes from different percentage of wind penetration as well as replacing synchronous generator with wind turbine generators. This centralized controller has some reserve input and output channels to deal with possible communication dropouts. It is based on loop shaping. The method is applied to a two-areas, four machines system under multi-model uncertainty, uncertain time delay, etc..
