Storage and integration: Energy storage standardization into the "in progress"! Security issues are

Recently, the National Energy Administration issued the "Action Plan for Peaking Energy Carbon Carbon Neutralization and Standardization Improvement", which systematically deployed the construction and optimization of the energy storage quality standard system. Industry insiders said, along with the implementation of the action plan, energy storage safety factor problem is expected to speed up deciphering.

Energy storage is the core technology to ensure the scale and stable connection of renewable energy with intermittent performance, such as wind power generation and photovoltaic power generation. Under the guidance of China's "dual carbon" goal, the energy storage industry chain has gradually developed into a major star industry chain.

In 2021, the National Development and Reform Commission and the National Energy Administration jointly issued the Implementation Opinions on Accelerating the Development Trend of New Energy Storage, which clearly proposed that the installed scale of new energy storage should reach more than 300 billion kW by 2025. From 2022 to 2025, the installed capacity of new energy storage will increase at an average annual rate of about 65%.

In terms of pumped storage, in the medium and long-term Construction Plan of Pumped Storage (2021-2035) published by the State Administration of Energy in 2021, it is clearly proposed that by 2025, the total scale of pumped storage completed and put into operation will double that of the 13th Five-Year Plan, reaching over 620 billion kilowatts. By 2030, the total pumped storage capacity in operation will double from the 145th Five-Year Plan to around 120 million KWH.

"With the gradual increase of renewable energy share, the energy storage industry development indoor space is very broad." Open source securities energy decoration industry chief analyst Zhang Xucheng said.

However, with the acceleration of energy storage engineering projects, the safety factor problem slowly surfaced, restricting the field of sustainable development concept of physical and mental health. Especially in the new energy storage industry, which mainly focuses on photocatalytic energy storage, the fire and explosion accidents of energy storage machines such as lithium batteries have been increasing, causing concern.

Several interviews with professionals previously told reporters, lithium-ion battery energy storage at this stage is still a photoelectric catalysis energy storage mainstream technology solutions, after all, different storage company cost control, plus after scale photoelectric catalysis, energy storage industry and detect test standard management system is still not perfect, some of the energy storage battery charge system security still difficult to accurately assess how. Therefore, the industry calls for further strengthening the standardized construction of energy storage are very high.

"At the present stage, the technical standards of power lithium batteries for energy storage are not perfect, and safety risks still exist. Under the premise of constantly improving the safety system of rechargeable batteries, relevant standards and specifications should be improved." Guo Yue, a member of the energy storage standard Committee of power engineering across the country, said that one is to improve the construction of inspection standards, improve the access conditions for use; Two is the standard operation management specification, system software quality supervision and other related work; The third is to create fire safety equipment and acceptance requirements, to ensure that the risk can be controlled.

"Energy storage project management specifications and specifications should be continuously optimized to various scenarios, and the contradictions and contradictions with overall planning should be handled well." CCCC shares and physical power industry Association energy storage Association chairman think.

From the perspective of Wang De and other industry insiders, the action plan announced this time has answered the public's concern and brought support for the sustainable development of energy storage power plant project life cycle.

The action plan clearly states that, according to the requirements of the integration of source, network, load and storage in the allocation of new energy generation, a quality standard system including the construction project of new energy storage, the whole process of production and operation, as well as the relevant technical details of environmental protection and pollution-free, quality management and so on should be established immediately. Optimize the connected power grid of energy storage power plants and the types of application fields, and improve the comprehensive safety design, detection and collection specifications of the connected power grid; We will accelerate the formulation of mandatory national industry standards for the safety of new energy storage systems, such as lithium batteries for energy storage and energy storage power plants. In combination with the innovation of new energy storage technologies and the expansion of their application fields, we will immediately revise the technical standards, and comprehensively promote the coordinated development of various new energy storage research and development technologies, demonstration applications and standards.

The plan also points out that by 2030, an optimized structure, excellent, scientific and reasonable energy quality standard system will be established, energy requirements will develop closely with technological innovation and industrial upgrading, and energy standardization will effectively guarantee and ensure carbon emission reduction and trading in the energy sector.
