Addressing the security of a future sustainable power system: The Danish SOSPO project

Current power systems have been undergoing in depth changes by the increasing share of renewable generation. At one hand, the grid is progressively more interconnected in order to collect the renewable generation from geographically dispersed places and to reduce the risks of intermittency; on the other hand, the power is increasingly generated at relative low voltage networks which in turn gives rise to new challenges in the conventional system design. The ambitious Danish governmental objective of greenhouse gas reduction accelerates adoptation of the renewables. The effect of this has to be carefully evaluated to secure the operation at both transmission and distribution levels. The fluctuations from wind and solar may rapidly degradate the security of the system such as overloading, voltage stability issues, etc. The Danish SOSPO project is launched from 2012 targeting at the system security assessment in the control room for the future scenarios. Methods will be developed in this project to counteract with the future challenges, and a testing platform will be developed in the laboratory for algorithm testing and demonstration.
