2009-05 Coordinated power flow control in transmission networks
September 23-25, 2009


Since the opening of the European electricity markets, cross-border trading of electrical energy has yield to higher power flows across the tie lines between the control areas. Additionally, the rising penetration level of non dispatchable generation leads to higher utilisation of the power flow.

As a consequence, a rising number of bottlenecks occur. In the recent years transmission system operators (TSOs) have installed several Power Flow Controllers (PFC) to disarm the bottlenecks. In areas with high accumulation of PFCs the mutual influence of adjacent units yields a shift but not an elimination of the bottleneck, because the free capacity of a parallel path might be claimed by several PFCs at the same time leading to an overloading of the parallel path. To achieve high transfer capability over a wide area, a coordinated operation of PFCs is needed, which is the focus of this course.

After an initial discussion of congestion management for the avoidance of loop flows in the UCTE this course presents technical details on common and innovative power flow controlling devices. Different approaches for the coordination of these devices will be explained. The approaches range from today’s state of the art to new approaches presented by members of universities. Finally it will be discussed how to determine the value in the market of power flow control and its coordination.
