The motions of nuclei in a molecule can be mathematically described by using normal modes of vibration, which form a complete orthonormal basis. Each normal mode describes oscillatory motion at a frequency determined by the momentum of the nuclei. Ne

There are very often scenarios when an accurate overview of the entire grid at an extra-large (even global) scale is needed, in order to perform estimations and predictions regarding grid events. In such scenarios data consistency plays a crucial rol

The future power system will integrate widely distributed energy resources (DER) interfaced by power electronics units, which may cause a reduction of the system inertia, resulting in non-compatibility with existing control algorithms and settings. A
