Power System Balancing by Distributed Energy Resources and Flexible DemandIn future power systems distributed energy resources and flexible demand is expected to contribute to power system balancing. In this presentation we suggest an approach based on two control concepts: Frequency controlled demand, and a 5-minute real-time market. To illustrate the concept we use a detailed physical modeling of selected devices in connection with an inertia model of the power system, and the two control concepts. The models are partly based on laboratory experience, partly on literature studies. The results show the behavior of the individual technologies as well as the aggregate behavior of a power system balanced by a coherent set of resources. The results prove that the concepts are feasible. Outline of a planned large-scale demonstration will be provided.
