Co-Simulation of a Nuclear Power Plant for Grid Interaction Studies

Power system dynamics are evolving rapidly due to the increasing penetration of power electronic interfaced devices. Nuclear power plants face new challenges in maintaining adequate power quality under altered external grid dynamics while ensuring consistency with nuclear safety analyses. This motivates the need for more detailed studies in which a broader set of parameters in the plant’s thermomechanical and automation process can influence, and be influenced by, the on- and offsite electrical grid.
