On the morning of April 11, Envision Energy Storage officially released EnPower, the world's first new smart energy storage system for new energy systems.
As the basic unit of the new energy system, EnPower smart energy storage is designed according to the needs of the new energy system, which is safer, higher performance, and lower LCOE, and is suitable for large-scale and high-performance deployment of energy storage. Integrate AI and new energy system technologies to promote the "better integration" of energy storage with the power market and power system, and help the efficient and stable operation of the high-proportion new energy power system.
Envision EnPower smart energy storage is equipped with Envision Power's new generation of 350Ah energy storage cells, with a cycle life of 15,000 times, AC and DC integrated design, one cluster and one management, eliminating inter-cluster circulation, increasing the discharge capacity of the whole life cycle by more than 8%, and the dual liquid cooling is highly integrated, with a standard 20-foot container capacity of 5.6MWh, and the energy density has reached a new high, which is also the world's first "AC-DC integrated" 5.6MWh energy storage system.
The new generation of smart energy storage system supports shoulder to shoulder, back-to-back, and a single energy storage unit exceeds 22MWh, which is 50% less than the footprint of the previous generation of liquid cooling products; The "AC-DC integration" structure can make the DC cable not go out of the cabinet, and it can be pre-installed and pre-debugged before leaving the factory, which greatly reduces the installation and commissioning time.
Compared with the mainstream products in the market at this stage, EnPower smart energy storage can reduce the LCOE of the whole life cycle by 45%, and the "AC-DC integration" structure has better performance and more convenient operation and maintenance in the life cycle, which is suitable for large-scale and high-performance deployment of energy storage and helps the construction of new energy systems.
Based on Envision EnOS™ intelligent IoT operating system, Envision Energy Storage integrates big data intelligent technology into EnPower smart energy storage, integrates intelligent transaction and intelligent production on the EnOS energy storage management platform, and integrates production, trading, operation and maintenance, improving production efficiency and reducing operation and maintenance costs.
Based on the new AI big data model, EnPower smart energy storage integrates production and marketing according to data sets such as grid dispatching instructions, market transaction dynamics, climate change, equipment operation data, and production management plans, so as to realize the optimization of trading strategies and the closed-loop control of closed-loop.
Compared with the previous generation of intelligent trading solutions, Envision's new generation of integrated production and marketing platform supports the strategy optimization of multiple trading varieties, takes into account the control strategy of the characteristics of trading varieties and battery life, formulates differential charging and discharging strategies based on battery status, improves the transaction income of energy storage in the whole life cycle, and supports the optimal performance of energy storage in power market transactions.
The EnPower smart energy storage released this time is also equipped with Envision's latest GenGrid generative grid technology, "1+4" full-stack network construction, with inertia support, voltage support, broadband oscillation suppression, enhanced grid strength, station-level black start and other network construction capabilities, supporting the stable operation of a high proportion of new energy power systems.
"1" refers to the full-time scale system simulation platform built by Envision, which can accurately define equipment characteristics, simulate modeling, and design and develop the best network-building products according to the application scenarios, development stages, and scale structures of new power systems. "4" refers to 4 hierarchical network products, covering components, complete machines, stations, and systems.
The component end is a self-developed grid-based energy storage converter, the stand-alone end is a high-performance grid-based energy storage unit that can be adapted to the grid-based energy storage converter, and the station end supports the synchronous motor characteristics of new energy station + energy storage collaboration, and the system end can realize the independent networking of source, load and storage.
Qian Zhenhua, CTO of Envision Energy Storage, said: "The new energy system faces three major challenges: flexibility, stability and economy. In the future, energy storage will play the role of both a 'voltage regulator' and a 'power bank' in the new energy system, supporting the construction of a resilient system and obtaining variable benefits in the power market. ”
Envision Energy Storage continues to lead technological change and promote energy storage applications around the world. According to the statistics of third-party authoritative institutions, Envision energy storage shipments in 2023 will be the fourth in China and the fifth in the world. At present, Envision Energy Storage has participated in more than 200 projects around the world, delivering more than 10GWh, including large-scale energy storage projects such as the Jurong Island project in Singapore and the Wormald Green project in the United Kingdom, with more than 15GWh of orders in hand.
