Verification of Grid Connection Conformity: FGW launches consultation for Technical Guidelines TG 3, TG 4 and TG 8

Berlin, Germany - The Fördergesellschaft Windenergie und andere Dezentrale Energien (FGW e.V.) will launch a public and bilingual consultation procedure (German/English) on the current drafts of the FGW Technical Guidelines TG 3, TG 4 and TG 8.

TG 3 deals with the etermination of the electrical characteristics of power generating units and systems in medium-, high- and extra-high voltage grids. TG 4 deals with the demands on modelling and validating simulation models of the electrical characteristics of power generating units and systems. Theme of TG 8 is the certification of the electrical characteristics of power generating units and systems in low-, medium-, high- and extra-high voltage grids.

The public consultation procedure is intended to offer companies without membership of the FGW as well as international companies the opportunity to comment and should thus ensure more transparency.

The focus of the work for the new revisions was on correcting errors, restructuring and implementing deferred work from the last revision. Furthermore, the results from the research project Network Harmony were transferred to TG 3. A relevant topic in TG 4 was the establishment of a procedure for EMT models, with which aspects relevant to offshore wind farms were included for the first time, as well as the integration of initial approaches to generic, platform-independent models. In TG 8, the verification procedure for extra high voltage is implemented.

The three independent public consultations on the three guidelines take place at different times. The public consultation of TG 3 will start on 19.07.2021, that of TG 4 on 23.08.2021 and that of TG 8 at the beginning of 2022. The publication of TG 3 (Rev. 26) and TG 4 (Rev. 10) is planned for mid-2022 and that of TG 8 (Rev. 10) for the end of 2022.

Conditions for participation in the public consultation as well as the exact procedure are published on the FGW website.
