The SIGUARD PDP is suitable for reliable system operation with wide area monitoring. The load of electric supply systems continue to increase over the years. There are different reasons for this. One could be the increase in cross-border power trading. Another could be new demands in tie lines between control areas.
The European grid has increased power transmission to almost six times starting from 1,975 to 2,008 according to the Statistical Yearbook of ENTSO-E 2008. Planned shutdown of existing power plants as well as an increase in the input of wind power will widen the transmission distance between customers and generation.
Storms and extreme weather conditions have also put critical lines out of operation giving the remaining grids a sudden increase in load. As a result, power systems have come increasingly closer to their stability limit as new load flow continues rising.
