METHODOLOGY FOR QUALITY CHECK OF COMMON GRID MODELS Abstract— One of the main services delivered by Regional Security Coordinators – RSCs is validation of individual grid models, as well as delivery of common grid models of Continental Europe. Common grid models present starting point for all rest RSC services, given that they are the basis for power flow calculation, security analysis etc. In the frame of Horizon 2020 project CROSSBOW methodology for quality check of common grid models is

... oped, basing on the comparison between forecast values and corresponding measured values for voltages, active and reactive power flow for the most relevant network elements in the region of Southeast Europe. For the purpose of this methodology, the dedicated module within CROSSBOW WAMAS product is created. The aim of this paper is to describe algorithm and architecture of the system that is used for realization of the methodology for quality check of common grid models, to describe quality indicators of common grid models and to show results of the given methodology obtained through developed software tool.
