　　The key to developing energy storage lies in the advancement of battery technology

　　Recently, at the "2018 Smart Energy Development Summit Forum" hosted by the China Electricity Council, participating representatives conducted in-depth discussions on hot topics such as "Internet +" smart energy, regional energy transformation, comprehensive energy services, and energy storage technology trends. .

　　Microgrid is an important component of smart grid

　　"Looking at today's energy development, the traditional era of single power generation and single transmission is gone forever. We have fully opened the era of 'Internet +' smart energy." Fei Zhi, President of GCL Smart Energy Co., Ltd., believes that the new era has great influence on energy. Development has put forward the requirements of cleanliness, intelligence, efficiency, safety and reliability. With the large-scale application of renewable energy and the continuous maturity of information technologies such as the Internet and the Internet of Things, vigorously developing the energy Internet has become an irreversible trend. It has also become an era proposition that global new energy companies urgently need to explore and actively respond to.

　　Microgrids are considered by the industry to be an important part of the energy Internet. According to experts, as a new energy network supply and management technology, the energy of microgrids is not strictly defined, ranging from tens of kilowatts to tens of megawatts. Its role is to coordinate the originally dispersed distributed power sources with each other to ensure the reliability and security of the distribution network. At the same time, it can smoothly connect to the renewable energy system and realize user demand side management and existing energy and resources. of maximum utilization.

　　Compared with traditional power grids, the biggest feature of microgrids is that they can digest and balance distributed energy on-site, and can also exchange energy with large power grids. For this reason, microgrids are considered an important part of the smart grid field and have broad application prospects in industrial and commercial areas, urban areas, and remote areas.

　　“In the long run, the development of microgrids is very important. In the foreseeable future, with the advancement of distributed renewable energy storage microgrid technology, cost reduction, and the emergence of new loads, combined with the reform of the electricity sales side, microgrids will There will be an increasing share of the electricity market," said Tang Xuewen, director of the New Energy Division of the Jiangsu Provincial Energy Bureau.

　　However, some industry experts said that microgrid research is currently in the ascendant, especially in terms of raw materials, components, components, system software networks, etc. that are the basis of the industry. There are still many topics that require in-depth research.

　　The key to developing energy storage lies in the advancement of battery technology

　　Energy storage technology is considered the “last mile” of new energy development. The so-called energy storage is to store secondary energy through chemical or physical methods to realize the transfer of energy in time and space. Experts said that the reason for developing energy storage is because energy storage meets people's needs for portable and mobile equipment in production and life.

　　At present, my country's new energy development momentum is very rapid. According to the plan, the installed capacity of wind power and photovoltaic will reach 1 billion kilowatts in 2050. However, along with the development of new energy, the phenomenon of wind and light abandonment is very serious. The reason is that new energy power generation is unstable and intermittent, and large-scale development and utilization will make the contradiction between supply and demand more prominent. In a sense, the degree of application of energy storage technology will determine the development level of new energy.
