Robust distributed H∞ control of electrical power systems

We consider the problem of synthesizing an optimal robust distributed controller for real-time power balance control in large-scale electrical power systems. Various sufficient robust performance analysis results are summarized together with a computationally tractable distributed controller synthesis algorithm. The proposed synthesis algorithm is tested on a benchmark example of a multi-area power system. The closed loop performance with obtained robust distributed controller is compared with performance of the optimal centralized H_∞ controller.
