Abstract

Electrical distribution grids are facing the integration of new grid participants, e.g. distributed generators or electric vehicles. High shares of new grid participants cause new load flow situations within the grid and topology changes in distribution grid planning, thereby affecting grid planning, protection and reliability. During grid faults and restoration process, grid topology and load flow situations change, potentially leading to voltage violations and equipment overloads and thereby to further unavailability of consumers or distributed generators. For an exact reliability assessment, an enhanced determination of relevant network operating points considering new grid participants has to be conducted. In this contribution, a determination method based on clustering of time series is presented and exemplary results based on real distribution grids are shown. Results emphasize that the relevance of an exact determination depends on grid and distributed generator technology type.
