In the context of today's global pursuit of carbon peak and carbon neutrality, the new energy industry has ushered in unprecedented development opportunities, which has not only injected new vitality into economic growth, but also spawned countless business innovations. With the vigorous development of the new energy industry, the energy storage industry has also sprung up like mushrooms after a rain and has become a technological highland in the new era.
Clean energy sources such as solar, wind and hydroelectric power are green and sustainable, but their output is heavily affected by weather changes. The alternation of day and night, the unpredictable skies, and the alternation of the rainy season and the dry season all make the output of new energy generation unstable. At the same time, people's daily production work is also facing the challenge of peak and trough electricity consumption. How to effectively store excess electricity during peak power generation and avoid waste has become a major problem in front of us.
In order to solve this problem, various energy storage technologies have emerged. Physical flywheel power storage, pumped water energy storage, chemical battery energy storage, etc., all provide solutions for the storage and utilization of electric energy to varying degrees. However, these technologies are not perfect, and the existence of secondary disasters makes us have to be vigilant to potential risks while enjoying the convenience brought by technology.
In this context, the emergence of distributed energy storage technology provides us with a new solution. It can not only greatly eliminate the hidden dangers of secondary disasters, but also realize the decentralized storage and local utilization of electric energy, and improve the stability and efficiency of the entire power system.
At the same time, we cannot ignore the proportion of building energy consumption in the total energy consumption of the whole society. According to statistics, China's building energy consumption accounts for 46% of the total energy consumption of the whole society7%, of which heating accounts for about 70% of the building's energy consumption. This is undoubtedly a huge energy consumption point. If the cold and heat storage mobile air conditioner can be used to store cold and heat energy at night and reuse it during the day, or the surplus electric energy of photovoltaic power and wind power can be stored, it can not only reduce electricity expenses for users, but also achieve the effect of peak shaving and valley filling, and improve the overall operation efficiency of the power system.
Therefore, vigorously developing energy storage technology, especially distributed energy storage technology, has become an important way for us to meet the new energy era and achieve sustainable development.
