Hierarchical control for power systems with high wind penetration


K. Margellos, J. Lygeros

Fifth IntelliCIS Workshop, Milan, Italy

In this talk we consider the case of power networks with a significant amount of wind power. A hierarchical structure is proposed, by applying different control techniques at each layer of the hierarchy, starting at the level of single wind turbines and building up to the integration of entire wind farms into the power network. We concentrate on the problem of optimal reserve scheduling from the point of view of the operator of the system. The problem is formulated as a linear program with chance constraints, and a Markov chain-based model is employed for generating realistic wind scenarios. Preliminary results are provided, and the advantages and limitations of the method are highlighted.
