For a long time, the industry has been paying more attention to installed scale, unit cost and initial configuration. Now, with the increasing diversity of revenue models and the continuous lengthening of project operation cycles, the industry’s focus has also changed: more and more focused on whether the system can operate stably for a longer period of time and continue to realize the revenue. This means that the competition for large reserves is shifting from “equipment delivery” to competition for “long-term value capabilities. What really determines the performance of the project is not only the level of a certain parameter, but whether safety, efficiency, scheduling, operation and maintenance and service capabilities can form a joint force to jointly support the long-term operation of the power station.
Around this trend, JA Energy Storage has launched a large-scale energy storage system JAGalaxy, which combines digital energy solutions with full life cycle service capabilities to further extend the value focus of large storage products from “building a project” to “operating a power station well for a long time”.
01
safety and performance
form the basis of long-term value of power station
For large energy storage power station, the premise of long-term value, it is the system that can operate continuously and stably under complex working conditions. Whether it is new energy distribution and storage, grid-side applications, or large-scale load-side scenarios, once the project enters the operation period, the real impact on value realization is often not the rated parameters at a certain point in time, but the safety boundary, fault control capability and performance stability in many years of operation.
1 System-level security is the starting point of long-term value
JAGalaxy build a multi-level security protection system covering monitoring, early warning, isolation and disposal from the system level, through the design of multi-level fuse protection, insulation monitoring, thermal runaway warning, layered detection and fire linkage, the risk of abnormal diffusion and unplanned outage is reduced as much as possible. For large power plants, the significance of this type of capability is not only “safer”, but also to reduce the loss of availability and fluctuations in operation and maintenance costs caused by failures, laying the foundation for long-term stable operation.
2 Thermal management and consistency control are related to long-term performance
Energy storage power stations are not short-term assets, and their value largely depends on whether the system can maintain stable output in long-term operation. JAGalaxy adopting the liquid cooling temperature control scheme, the battery working temperature can be controlled below 35 ℃ and the temperature difference can be controlled within 3 ℃, thus improving the system consistency and slowing down the performance differentiation and attenuation in long-term operation. With long-life LFP cells, the system can better balance safety, stability and life performance in long-cycle application scenarios.
3 Efficiency optimization is also essentially revenue capability
With the energy storage revenue model moving from single to multiple, project revenue increasingly depends on whether the system can stably execute the scheduling strategy. Higher system efficiency, lower auxiliary energy consumption, and more stable available charge and discharge capacity will directly affect the actual operating performance of the project. For large-scale energy storage power stations, the efficiency value is not only reflected in the lower loss of a single operation, but also in helping the project to maintain a more stable income cashing ability in the long-term operation.
02
digital operation
improve the long-term income level of the power station
If the hardware system determines the performance foundation and safety boundary of the power station, then the expansion of digital capability, it is the scheduling accuracy, operation and maintenance efficiency and revenue management level of the project in the long-term operation.
As the energy storage industry moves from construction-oriented to operation-oriented, the differences between power stations are increasingly reflected in “whether the system can be used well for a long time”. Around this point, Jingao energy storage has created the Jingao Nebula™Digital energy solutions (JANebula) to further enhance the fine operation capacity of large-scale energy storage projects.
1 Find problems earlier and reduce passive downtime
In large energy storage projects, the earlier the fault is found, the lower the disposal cost is usually. Relying on the predictive maintenance capability driven by Jingao Nebula, it can realize state monitoring from the battery core to the system level, continuously sense key operating parameters, and detect potential abnormalities earlier through intelligent alarm and fault identification, thus reducing unexpected downtime. At the same time, it supports remote fault diagnosis and software upgrade. The above problems can be solved online, pushing operation and maintenance to shift from post-response to pre-intervention.
2 More flexible to adapt to changes in revenue scenarios
The long-term benefits of large-scale energy storage projects are not statically formed. With the change of market rules and the improvement of scheduling requirements, whether the system has stronger adaptability is becoming more and more important. The JA Nebula can support multiple types of energy management strategies such as peak cutting and valley filling, dynamic demand management, dynamic capacity increase, and green power dissipation, and has strong system compatibility. The energy storage system can not only adapt to the current operating scenario, but also better respond to strategy adjustments and changes in revenue models in subsequent operations, enhancing the operational flexibility of the project.
3-side cloud collaboration makes long-term management more efficient
For cross-regional, overseas or less-attended projects, long-term operation and maintenance capabilities are directly related to project management costs and fault response efficiency. Based on the edge cloud deep collaboration architecture, the system can achieve millisecond response at the edge side, support upgrade, remote monitoring, intelligent early warning and fault diagnosis, help reduce the complexity of operation and maintenance, improve response efficiency. For large power plants, the significance of digital energy solutions is not only visualization, but also to break geographical restrictions and significantly improve operation and maintenance efficiency and full life cycle reliability.
03
whole life cycle service
tamping power station long-term operation support
energy storage power station is not a one-time delivery type asset, it is an energy infrastructure that needs to continue to deliver value over many years of operation. Therefore, the long-term value of the project depends not only on the product itself, but also on the improvement of comprehensive capabilities such as system integration, engineering delivery, post-service and expansion and upgrading.
JA energy storage products adopt standardized and modular design ideas, which can support flexible deployment and multi-machine combination, and reserve space for subsequent expansion and upgrading. For large projects, this ability is reflected in higher deployment efficiency in the early stage, and stronger scalability and adjustment space in the middle and late stages.
At the same time, JA Energy Storage is also continuously optimizing the full life cycle service capability covering scheme design, system integration, engineering delivery and long-term operation and maintenance. For large-scale energy storage projects, whether the failure response is timely, whether the service system is perfect, and whether overseas projects have localized support will affect long-term operational performance. More complete service and operation and maintenance support can reduce the uncertainty in the later stage and make the long-term value of the power station more sustainable.
Inner Mongolia Xing’an League Light Storage Project
This focus on long-term value has been fully reflected in actual projects. Taking the Xing’an League Light Storage Project in Inner Mongolia as an example, the project is equipped with photovoltaic and energy storage systems, which will be connected to the grid at the end of the year, mainly participating in auxiliary services such as, peak regulation and frequency regulation, while undertaking the task of reducing light abandonment and smoothing the power curve of photovoltaic power generation. The project has been running smoothly and efficiently for more than a month, verifying the long-term reliability, dispatch response capability and full life cycle service capability of the energy storage system under special conditions such as severe cold and sandstorm.
The long-term value of a power plant is no longer defined by a single parameter or initial cost, but by a system combination of safety, efficiency, digitization and life cycle services. Jingao Energy Storage deeply understands this transformation, with large-scale energy storage system as the cornerstone, fusion of the Jingao Nebula.™Digital energy solutions and full life cycle service capabilities extend competitiveness from “equipment delivery” to “long-term operations”.
When the industry really focuses on “how to operate a power station”, JA Energy Storage has prepared the system for the long-term value of customers, and relying on the “optical storage” integration concept, continue to expand the value boundary of energy storage, and promote the evolution of the energy system to a more efficient, flexible and sustainable direction.
