Temporary overvoltages and their impact on grid security - final results from the joint research project OVRTuere

The stability and security of electricity grids is of central importance for society and the economy. One potential technical risk, which grid operators have been giving increasing attention, is that of the potential large-scale tripping of generation plants due to temporary overvoltages. This paper makes recommendations about dealing with temporary overvoltages in the German power system, taking the increasing displacement of synchronous machines by inverter-based plants into consideration.
