On May 14, General Secretary Xi Jinping inspected the integrated demonstration project of Sino-Singapore Tianjin Eco-city smart grid. Xi Jinping is very concerned about the contents of strong smart grid, clean energy development, energy conservation and emission reduction, etc., and placed great hopes on the promotion and development of smart grid. As an important technical support unit in the development and construction of power grids, EPRI has played a leading role in scientific research in the core technology of smart grid and has become an important goal of our next step. In recent years, along with the rapid economic and social development in Tianjin, the contradiction between supply and demand of energy has become increasingly prominent. The problems of climate change and energy security have gradually raised the construction of smart grid to the national strategic level. According to the current national energy policy and power system status quo, Tianjin has proposed its own characteristics of micro-grid concept and development plan. At present, EPRI is working on the research of key technologies such as grid integration and energy storage of new energy sources and intelligent distribution of electricity. Not long ago, it just finished the centralized testing of the new generation of intelligent substation equipment in China Electric Power Research Institute. Completion of the work on the one hand for the Tianjin Hi-tech Park 110kV next-generation intelligent substation demonstration project provides an important technical support, on the other hand also raised the ASTRI in a new generation of intelligent substation overall testing, debugging capabilities and enhance the talent pool. In the meantime, a number of phased progress have also been made in the national 863 smart matching research project under the joint efforts of EPRI, which laid a solid technical foundation for the next project construction and implementation. In the face of the achievements, we did not stop without a hitch and Lijian felt more and more responsible. In the project of "Key Technology Research and Integration of Intelligent Microgrid Based on Distributed Power Supply" in the field of energy of the National Science and Technology Supporting Plan in 2014, under the leadership of the company's science and technology information department , EPRI is fortunate enough to participate in the project declaration process throughout the project. Based on the current status of eco-smart grid construction, EPRI conducted an in-depth study on distributed power supply access control, home energy efficiency management, microgrid condition monitoring and operation management, By coordinating and optimizing the energy of multi-microgrids in the areas of light, gas and geothermal, the ability of high-penetration and in situ consumption of renewable energy sources will be further enhanced and the comprehensive energy efficiency of new energy sources will be further enhanced. Just as General Secretary Xi Jinping inspected Tianjin in the east , To provide a model for building a resource-saving and environment-friendly society. At present, the Tianjin company stand out in the internal review of the national network system. Next, as the lead unit, Tianjin Company will actively organize the assessment of three provincial provincial companies and related research institutes, universities and sprint Ministry of Science and Technology. The general secretary Xi fully affirmed the comprehensive demonstration project of Sino-Singapore Tianjin Eco-city smart grid and inspired every EPRI, and we will certainly work hard to be the first to concentrate, borrow good power, high standard and high quality to complete the project Goal for Tianjin smart grid construction to provide a strong technical support and protection of the construction of new energy sources in Tianjin to a new level; and then create the national pilot area of ​​smart grid pilot flagship, in the tide of scientific development, sail.
