Distributed H∞-based control of Electrical Power Systems

We consider the optimal network frequency control in electrical power systems. The overall power system consists of several subsystems distributed over a network. We implement a method of synthesizing a distributed dynamic output feedback controller (Langbort et al., 2004a) for such a system consisting of several subsystems distributed over an arbitrary graph. This H∞-based distributed approach is then compared with the classical AGC controller, the centralized H∞ solution and different MPC approaches.
