Battery energy storage has become the cornerstone of energy Internet
The concept of Energy Internet is extended from "Internet +", which is a high degree of integration of information network, energy network and energy network. The Energy Internet takes the power network as the hub platform, takes renewable energy and distributed energy access as the main task, and uses Internet technology as the realization tool to implement wide-area optimization and coordination of renewable energy and distributed energy infrastructure through the energy regulation system. Realize the optimization and complementarity of cold, heat, gas, water, electricity and other forms of energy, thereby improving the efficiency of energy use and realizing the two-way flow and sharing of information, energy and energy.
Liao Yu, chairman of the German Chinese New Energy Association, believes that the Energy Internet is not just "energy + Internet", or selling energy on the Internet, but a full connection to the entire energy supply and sales network. This kind of full connection can sense, analyze, and integrate various key information through information technology and communication technology means such as Internet of Things infrastructure, cloud computing data center, and geospatial monitoring equipment, and make intelligent responses to various energy needs.
The Energy Internet interconnects many nodes in energy and energy production, conversion, storage, transmission, and use, and realizes free access, real-time flow, instant exchange and sharing of information flow, energy flow, and energy flow. Energy network, "three networks in one" of energy network.
After the "Guiding Opinions on Promoting the Development of "Internet+" Smart Energy" and "Notice of the National Energy Administration on Organizing and Implementing "Internet+" Smart Energy (Energy Internet) Demonstration Projects" were successively issued, March 6, 2017 On the 1st, the National Energy Administration announced the list of the first batch of "Internet +" smart energy (Energy Internet) demonstration projects. A total of 56 projects entered the demonstration list, which means that my country has taken a substantial step towards the Energy Internet at the implementation level. The curtain has opened.
Energy storage: a key technical link of the energy Internet
Energy, the main load of the Energy Internet, mainly comes from nature. Clean energy such as wind energy and solar energy has the characteristics of discontinuity and instability. Energy storage technology can solve the randomness and volatility of new energy power generation to a large extent. The smooth output of new energy power generation can be realized, and large-scale renewable energy power can be reliably integrated into the grid.Also read:https://www.aimeno.com/lithium-battery-pack/195.html
On the consumption side of the Energy Internet, energy storage technology is to solve the problem of energy substitution, such as replacing fuel vehicles with pure electric vehicles. Lin Boqiang, dean of the China Energy Policy Research Institute of Xiamen University, believes that energy storage is indispensable in the development of clean energy, and it is the core module that determines the future development trend of clean energy. Regardless of the supply side or the consumption side, energy storage is the core component of the Energy Internet, and it is an important factor for the success of the Energy Internet.
Regarding the future energy storage market, the "13th Five-Year Plan for Renewable Energy Development" proposes that by 2020, my country's photovoltaic power generation will reach 105 million kilowatts, solar thermal power generation will reach 5 million kilowatts, and wind power will reach 210 million kilowatts; , The installed capacity of renewable energy power generation is 680 million kilowatts, and the power generation capacity is 1.9 trillion kwh, which is expected to account for 27% of the total power generation. With the large-scale development of clean energy such as wind power and photovoltaics, energy storage can solve the problem of grid connection and consumption. It is foreseeable that the large-scale development of my country's energy storage market is about to start.
Lithium-ion batteries are currently the fastest-growing energy storage technology. According to statistics from industry organizations, in 2020, China's lithium battery energy storage market demand will reach 16.64GWH. Based on the current installed capacity, the cumulative demand for lithium batteries in the next five years will reach 45.59GWH. Based on this, major energy storage lithium battery manufacturers are actively deploying in the field of energy storage. For example, Dynavolt Technology has cooperated with countries along the “Belt and Road” and plans to invest 400 million US dollars in Pakistan in the next few years for energy storage batteries, etc. In the field of clean energy, a large number of energy storage facilities have also been established in Nepal, India, Bangladesh and other countries, and the international energy storage market is actively deployed; Vision shares will increase 825 million yuan for lithium battery expansion, and plans to install a 600MWh production line in 2017. And allocate them to power batteries, communication batteries and energy storage batteries at a ratio of 7:2:1; in addition, Kelu Electronics and LG Chem established a Sino-foreign joint venture to develop energy storage battery packs and deploy energy storage fields.
Energy storage is a key technical link of the Energy Internet. Emerging energy storage technologies such as compressed air energy storage, electrochemical energy storage, and superconducting magnetic energy storage are the direction of future energy storage. At present, energy storage batteries represented by sodium-sulfur batteries, flow batteries, lithium-ion batteries, and lead-acid batteries have also become the basis for the development of the Energy Internet.
At the "Smart Energy International Forum", Professor Xie Jingying from the University of California, Berkeley mentioned the heat and safety of the energy storage battery system, the power battery system and performance prediction, the data system of the energy storage system, and battery failure analysis. The key to the Internet of Energy Technology, all around the battery. Therefore, in the building of the Energy Internet, the battery is the cornerstone of the building, and it is the basis for the operation of the Energy Internet.Also read:24V 300Ah Lithium Battery
The advent of the Energy Internet means that we will subvert all previous views and experiences on energy, and we will usher in a new era of energy, and batteries will become the "stepping stone" of this new era. Whether the Energy Internet can develop smoothly is a sign of our proficiency in the use of existing and future energy technologies, and it is also a sign of whether we can live in harmony with the power of nature, and batteries will also become a "stepping stone" for the harmonious development of man and nature .
