On January 10, 2025, the first working group meeting of the IEC/TC4/WG14/PT1 "Hydropower Station Joint Control Technology Standard" domestic correspondent working group, hosted by NARI Hydropower Company, was held in Nanjing. More than 40 experts and representatives from over 20 entities, including State Grid Corporation of China, China Southern Power Grid Co., Ltd., power generation group companies, hydropower plants, design institutes, scientific research institutions, and universities, participated in the meeting.

During the meeting, the Secretariat of the National Turbine Standardization Technical Committee announced the approval for the establishment of the IEC/TC4/WG14/PT1 Chinese correspondent working group. NARI Hydropower Company provided a detailed report on the preliminary work of IEC 63599 "Hydropower Station Joint Control Technology Standard" and the working group draft. The participating experts engaged in comprehensive discussions regarding the rationality of the working group's framework structure and the comprehensiveness of the technical content, and put forward constructive opinions and suggestions.

This meeting further clarified the compilation direction and objectives of IEC 63599 "Hydropower Station Joint Control Technology Standard", and formulated a detailed plan for subsequent work. The members of the IEC/TC4/WG14/PT1 domestic correspondent working group expressed their intention to actively contribute according to their professional expertise and jointly promote the compilation of the standard.

The international standard of IEC 63599 "Hydropower Station Joint Control Technology Standard" was officially approved and initiated in July 2024. The standard compilation work is being carried out under the auspices of the IEC/TC4/WG14 working group, with NARI Hydropower Company serving as the project convener. This represents another significant breakthrough in the field of international standardization, following the release of the international dual-standard of IEC/IEEE 63198-2775 "Technical Guidelines for Smart Hydropower Plants". The formulation of this standard is of great importance for further maximizing the peak-shaving and frequency-modulation capabilities, as well as reliable and flexible regulation capabilities of hydropower stations, and for better supporting the construction and operation of large-scale renewable energy and the global energy green transition.
