10WG E3: Europe: Improving transmission capacity of power systems with a high level of distributed and renewable generation — Dynamic network and protection security, assessment and measurement

THE increase of the penetration of stochastic renewable generation requires new strategies in the system operation. On one hand the transmission capacity of the power system must be as high, as unplanned dynamics, caused by renewable infeeds, can be transported without producing system bottlenecks. Such dynamic energy transports occur sometimes over long distances and require operational coordination between different TSOs. On the other hand new indicators, describing the power system stability and the margins to stability limits must be developed and tested, which allow a prediction of the dynamic state of the power system if contingencies would occur.
