Decision support for network operation in an open power market

Abstract

SUMMARYThe Norwegian system operator plans to change from (N-1) to a more flexible cost-based security criterion. The approach is illustrated using a simple example and then compared with alternative decision paradigms. The comparison shows how different paradigms may change ranking of operating alternatives and that the new cost-based criterion still tends to favor alternatives close to (N-1), provided application of a penalty factor giving additional and significant weight on interruption costs.

Graph Convolutional Networks for probabilistic power system operational planning

“…In [5] a DC power flow was used to include power system response in a probabilistic operational planning model. Different costbased criteria are compared in [6], where a transport model was used to model the power system response. An AC power flow and a linear approximation of frequency response were used in [7] to include frequency response in an operational planning model.…”
