In June of this year, a new international standard, theIEEE Recommended Practice for the Planning and Design of the Microgrid (IEEE 2030.9-2019) was approved by the IEEE（Institute of Electrical and Electronics Engineers）Standards Board and officially released to the world. Experts from Tianjin University’s School of Electrical and Information Engineering were primarily responsible for the drafting of the standard.

The IEEE P2030.9 working group was established in 2015 and Professors Wenpeng Luan and Chengshan Wang from Tianjin University have since worked as the chairman and vice chairman respectively. In addition, experts from the State Grid Corporation of China, China Southern Power Grid, ABB China, Schneider Electric, Siemens, Sifang Automation, the China Energy Construction Holding Group, and the North China Electric Power University also participated in the preparation of the standards. In recognition of the release of this important standard and the selfless dedication of the experts, the IEEE Standards Association issued a commemorative certificate to the standard preparing group during the IEEE PES (Power & Energy Society) General Meeting held in Atlanta in early August this year.

The new microgrid planning and design standard includes sections on: microgrid planning and design process, microgrid planning, security, microgrid primary system design, microgrid protection configuration, monitoring and energy management, power quality monitoring and control, energy metering, communication, program evaluation and typical case analysis. Applicable to grid-connected microgrids and independent microgrids as well, this international standard is in particular concerned about microgrid planning and design, and provides design methods and recommended practices for power generation forecasting, load forecasting, system architecture, grounding, protection, energy management, and information exchange. The typical case study about grid-connected microgrids involved in the standards are actual practices once carried out in remote mountainous areas in China.

The release and implementation of this standard is of great significance for regulating the planning and design of microgrids and leading the sustainable development and application of global microgrid technology. It also provides strong support for the efficient consumption of clean energy and the healthy development of smart grid.
