IEC standard "distributed power and grid interconnection" released

June 15 was informed that by the China Electric Power Research Institute led the preparation of the International Electrotechnical Commission (IEC) standard "distributed power and power interconnection," was officially released. The standard proposal was initiated by State Grid Corporation of China. In February 2012, it was approved by IEC System Committee TC8. Thousand person plan expert and chief honorary chief engineer of China Electric Power Research Institute Yao Liangzhong served as convener. In April of the same year, a standard establishment start-up meeting was held. China and Germany, Italy, France, Denmark, Canada, Australia, Japan and other countries participated in the standard preparation of many experts. The standard as a distributed power supply connected to the technical specifications of the distribution network, and strive to reflect the results of various countries and distributed power grid technology development, to meet the diversity of distributed power and grid interconnection planning, design, grid and operation needs, covering The overall demand, and network options, the choice of switches, the normal operation range, anti-disturbance ability, reactive power and reactive power, power quality, interface protection, monitoring and control and communications and other aspects. Distributed power generation in the world rapid development, with rapid technological development, types, access conditions and diverse, technical requirements between countries, large differences in demand characteristics. Under the guidance of the State Grid International Department, the Ministry of Science and Technology, the Global Energy Internet Office and other departments, the China Electric Power Research Institute has set up a standard working group composed of experts in the field in this field and jointly tackled the difficulties in the preparation of joint standards. The release of this standard fills the blank of IEC standard for distributed power grid connection and strengthens the company's influence in the field of IEC technical standards and will guide the application of friendly interactive technology of distributed power and grid in the world and help China's "Internet + Smart Energy "action plan.
