Thank you for responding to reviewers' comments. The only one unclear is the first one "a suggestion of which work is most important for the future operation of the power system and why". You state generally "These new features necessitate new or reformed test standards in the near future" - do you mean that all the new features are equally important to address already?
I would also recommend to check the language of the paper to clarify the text that is in some parts having unnecessary long sentences and paragraphs. Check especially the Abstract (the use of "Besides..." I think that you mean that on top of harmonizing state-of-the-art test, new features are needed) and 5.4 Discussion and Introduction (use of Part 1... instead of Section 1...?, and try to be as clear in what you are proposing to do as in Conclusions.

Thank you for your careful consideration of the review comments, the paper is ready to publish.

Thank you for publishing with us,

Jakob Mann, Editor-in-Chief.
