According to statistics, in the first three quarters of 2022, the installed capacity of new energy storage projects newly put into operation in my country was 963.7 MW, a year-on-year increase of 120%. Against the background of market and policy resonance, energy storage companies ushered in an explosion of orders. According to industry reports, under the "dual carbon" goal, clean energy such as wind power and photovoltaics surge protection has achieved large-scale development.

At the same time, the volatility and intermittency of clean energy has brought great challenges to the safe and reliable operation of the power system. Energy storage can be real-frequency to ensure the smooth operation of the power system, which has become an indispensable part of the new power system. The new type of energy storage is one of the breakthroughs for the birth of a new business model of the energy industry and the creation of a new economic engine. At present, my country is building a new power system with new energy as the main body, and the new energy storage market has a broad space for development.

Since the beginning of this year, a number of policies have been introduced to accelerate the development of the energy storage industry. In March 2022, the "14th Five-Year" Modern Energy System Plan issued by the National Development and Reform Commission and the National Energy Administration proposes to build a new power system, apply new energy storage technologies on a large scale, and greatly improve the elasticity of power loads. New energy has the advantages of multi-dimensional observability, fast response, highly controllable all-electricity, high efficiency and energy saving. Compared with traditional energy, it can achieve a higher level of smart energy. In the new type of power with new energy as the main body, energy storage will be distributed in various scenarios of "source, network, and load", and play the role of "reservoir" and "grid regulator and stabilizer".

Under the goal of carbon neutrality, the future development direction of energy storage will be closer to specific application scenarios, and my country's energy transformation trend will continue to be zero-carbon, intelligent, and electrified. Introduction of energy storage lightning protection box: A special intelligent lightning protection box for energy storage should be installed at the entrance of the DC cable of the battery compartment to prevent external lightning overvoltage from invading the energy storage battery compartment system and causing equipment damage. The special intelligent lightning protection box for energy storage should utilize modern microcomputer communication technology to realize functions such as internal SPD operation status monitoring and lightning data monitoring.
