                Chairman of Bidding Committee and Director of Sheng Wanxing, Distribution Research Institute, China Academy of Electric Power Sciences, made the first report on the work of Bidding Committee in 2018, and gave the six-character policy of "timely, authoritative and effective" to the steady progress of Bidding Committee's work. Four requirements were put forward: First, Bidding Committee should further promote cooperation among grid system units, universities and enterprises, from top to bottom, from bottom to bottom. To deepen the technical exchanges among enterprises in an all-round way; to complete the standard revision work carefully to ensure the authority of standards; to pay attention to the effectiveness of standards, speed up the construction of standard verification bases and demonstration projects, and focus on industrial development to ensure the applicability of standards; and to strengthen the promotion of internationalization, push the practical experience and achievements of the bid committee over the international market with the help of CIG. RE, IEC and other international standardization platforms continue to enhance China's domestic and international influence in the field of DC distribution.

                ?Wu Ming, Secretary-General of the Bidding Committee, presented to the General Assembly a report on the work of the Secretariat of the Bidding Committee in 2018. He also reported to the General Assembly the revenue and expenditure of the Bidding Committee in 2018 and its budget for expenditure in 2019. This paper introduces the international work trends of the Secretariat such as IEC/CIGRE in 2018. The Bidding Committee fully supports the work of CIGRE SC C6.31 "DC Distribution Technology" Working Group, leads the completion of two special technical reports of "Research on DC Distribution Technology" and "Global Investigation of DC Distribution", organizes an international seminar on DC Distribution, and puts forward the DC Distribution Standard System at the 2018 IEC Conference in Busan, Korea. The above international work has effectively enhanced the leading power and influence of China's international standard-setting in this field. Next, the Secretariat introduced the standard project formulation and the work plan for 2019.
