APPLICATION FOR AUTOMATIC CREATION OF TOPOLOGY FILE NEEDED FOR CREATION OF NETWORK MODELS

The transmission system operator EMS JSC prepares day-ahead (DACF), two-day-ahead (D2CF) and intraday (IDCF) network models according to ENTSO-E requirements. With the aim of further improvement, ENTSO-E is increasingly insisting both on increasing the accuracy of network models and on the creation of additional models. The current goal is that in the near future, network models, in addition to the current ones, will be created daily for 24 hours for seven days in advance, as well as every hour within the day for all the remaining hours of the current day (instead of every 8 hours as is currently the case). As four input files are used to create network models (data on consumption, production, exchange and topology), there is a need to automate their creation in order to fulfill all the requirements imposed by ENTSO-E, which means reducing the impact of human errors and increasing the efficiency of the creation process of these models. The most complex file used for creating network models represents the planned topology of the system and it contains the topological status (on/off) of the network elements, that is, transmission lines, transformers and busbar couplers. In our system, the largest number of system topology changes are caused by planned works in the transmission system, so it is necessary to include this data in the topology file in an appropriate way. This paper provides an overview of all the activities that were carried out in order to establish the automatic creation of the topology file. The described activities were implemented through the European Horizon 2020 project Reliability, Resilience and Defense Technology for the Grid - R2D2 [2]. In addition to the making of the application itself for the automatic creation of a topological file, there is also a review of the extension of the model in the base of the technical information system, for all categorized elements (transmission lines, transformers, transmission fields, transformer fields, busbars, busbar disconnectors) and mapping with a unique cimID, as well as the extension of the already existing application for approving disconnections in the transmission system, which was all necessary in order to automate the creation of topological files.
