The energy storage revolution in the new energy era
With the continuous growth of new energy power generation capacity, the demand for large-capacity and high-efficiency energy storage systems in the power grid is increasing day by day. Traditional power systems have struggled to meet the flexibility and adjustability requirements of new power systems. As a key part of the development of new energy, energy storage technology is promoting the scientific and technological revolution in the energy field and has become an important force supporting the new power system.
The development of energy storage technology has been tortuous and arduous, but the prospects are broad. Although the early pumped storage was large-scale, it was difficult to select a site, the construction period was long, and the environmental impact was large. The new energy storage technology is flexible in location, fast in construction, environmentally friendly, and highly compatible with the characteristics of new energy power generation, and is highly hoped.
In recent years, the mainland government has issued a series of policies to vigorously support the development of the new energy storage industry, which has injected strong impetus into the development of the industry. Enterprises have increased R&D investment, new energy storage technologies and products continue to innovate, integration and energy density continue to improve, safety and economy are increasingly enhanced, and large-scale applications have broad prospects.
Why are 6MWh energy storage containers a trend?
The integration and energy density of an energy storage system are important indicators to measure its performance. The high level of integration means that more electricity can be stored per unit volume, which is conducive to improving the economy of the energy storage system. The high energy density reduces the footprint of the system and reduces the cost of land. Improving integration and energy density has always been the goal pursued by energy storage companies.
It is in this context that the 6MWh energy storage container came into being. It is designed in a standard 20-foot container with a high degree of integration, easy transportation and installation. Through the use of large-capacity cells, advanced battery technology and thermal management system, the 6MWh energy storage container achieves high energy density, increasing the energy density per unit area by more than 30% compared with traditional products, reducing the floor space by 20%, effectively reducing system investment and operating costs.
The 6MWh energy storage container also has a long cycle life and high safety. By innovating the battery material system, structural design and manufacturing process, battery companies have made the cycle life of energy storage batteries reach more than 15,000 times, effectively solving the problem of "life diving". Multiple safety protection measures ensure the safe operation of the system and eliminate the hidden dangers of fire and thermal runaway.
With the advantages of high integration, high energy density, long cycle life and excellent safety performance, the 6MWh energy storage container system meets the demand for large-capacity and high-efficiency energy storage systems in the development of new energy, and has become a trend in the development of energy storage systems.
Modular design, easy to transport and install
The 6MWh energy storage container adopts a modular design concept, which divides the energy storage system into multiple modules, each module is an independent subsystem, with standardized interfaces, which can achieve "plug and play". This design not only improves the reliability and maintainability of the system, but more importantly, it is easy to transport and install.
The standardized container design enables the 6MWh energy storage system to be efficiently dispatched through various transportation modes such as railways, highways, and shipping like ordinary cargo, which greatly reduces logistics costs. The modular design makes on-site installation very easy, and only needs to dock each module and complete simple wiring and commissioning, and then it can be put into operation, which effectively shortens the construction period and reduces labor costs.
The modular design also facilitates future expansion and maintenance. When the demand for energy storage increases, only new modules can be added, avoiding the trouble of reconstruction; When a module fails, it can also be serviced or replaced independently without affecting the operation of the entire system.
The modular design concept gives the 6MWh energy storage container the "flexible" characteristics, making it able to adapt to the needs of different application scenarios, which is conducive to the large-scale promotion and application of new energy storage technologies.
Advanced battery technology, long cycle life and high safety
The battery technology used in the 6MWh energy storage container is the highest level in the energy storage field today. Through long-term R&D investment, battery companies have made major breakthroughs in battery material systems, structural design and manufacturing processes, which have greatly improved the cycle life and safety performance of energy storage batteries.
In terms of material systems, battery companies have developed new cathode materials and electrolyte additives, which effectively inhibit the side reactions inside the battery and prolong the battery life. In terms of structural design, the "blade" or "laminated" cell structure is adopted to improve the consistency and thermal diffusion performance of the cell. In terms of manufacturing process, automated and intelligent production lines have been introduced to ensure the high quality and consistency of products.
With these innovative technologies, the cycle life of the battery used in the 6MWh energy storage container can reach more than 15,000 times, which effectively solves the problem of "life diving" and ensures the long-term stable operation of the system. Multiple safety protection measures, such as thermal runaway detection and double-sided liquid cooling, comprehensively improve the intrinsic safety of the battery and eliminate the hidden dangers of fire and thermal runaway.
Long cycle life and high safety are the core competitiveness of 6MWh energy storage containers, and they are also the key to replacing traditional energy storage technologies with new energy storage technologies. The future energy storage market will be a technology competition, who has mastered more advanced battery technology, can take the initiative in this competition.
The role of energy storage systems in new energy power generation
New energy power generation has the characteristics of intermittency, fluctuation and randomness, which brings great challenges to the balance regulation of the power grid. The energy storage system can provide power support and regulation for new energy power generation and improve the absorption capacity of new energy, which is the key to solving this problem.
The energy storage system can play multiple roles on the new energy generation side:
1. Peak shaving and valley filling to realize the time transfer of electricity. Store the surplus electricity of new energy power generation during the day, and release the electricity at night or during peak power consumption, so as to stabilize the power fluctuation of the power grid and improve the utilization efficiency of electricity.
2. Provide backup and frequency modulation capabilities. The energy storage system can respond quickly and provide auxiliary services such as rotating backup and frequency modulation for the power grid, improving the flexibility and reliability of the system.
3. Improve power quality. The energy storage system can absorb harmonics and inrush currents in the power grid, effectively improving the quality of power supply.
4. Promote the local consumption of new energy. Through the integrated mode of "new energy + energy storage", new energy power generation can be consumed to the greatest extent and the transmission loss of the transmission line can be reduced.
With the continuous growth of new energy power generation capacity, the role of energy storage system in the power system will become increasingly prominent. The large-capacity and high-efficiency 6MWh energy storage container system will surely provide strong support for the consumption of new energy power generation and the balanced regulation of the power grid.
