At present, energy storage power stations bloom everywhere, further testing the complex environment energy Storage System performance.

Recently, in the Qinghai-Tibet plateau with an altitude of 3700 meters, the solar power EMS3000 energy management system has helped Tibet's 8MW/40MWh energy storage project to operate normally for a whole year.

According to the understanding of high-tech energy storage, on the one hand, this application refreshed a new height of EMS3000 applications at high altitude, filled the gap in high-altitude applications, effectively promoted the absorption of local new energy sources, and improved the local power supply capacity, effectively help the stable operation of the new power system in Tibetan areas.

On the other hand, this application also verifies that EMS3000 has the energy management capability from a single energy storage system level to an optical storage station level.

Not only in the 3700-meter-high Tibet packing project, it is not afraid of "high reverse", but also performs well in the coordinated operation of optical storage at the station level.

In addition, in the GWh-level power station that has been connected to the grid recently, EMS, BMS and PCS of Sunshine power supply cooperate efficiently, and also show strong intelligent management capability of power station.

Overcome the "high reverse",

cell warning & intelligent O & M EMS broken

what is unknown is that energy storage systems, like people, also have & ldquo; High reverse ".

First of all, in high altitude areas, the air is thin and the oxygen content is low, and the system heat dispersion can be greatly reduced, resulting in equipment overheating, failure rate and operation and maintenance volume increase;

secondly, in high altitude areas, traffic is inconvenient, and operation and maintenance are difficult and costly under manual conditions. In order to ensure normal operation, higher requirements are put forward for monitoring and early warning of system equipment and intelligent operation and maintenance capability. First, under the environment of hypoxia and high temperature difference, the cooling performance of system equipment is reduced, and fault warning needs to be more accurate; Second, charging at low temperature leads to lithium evolution, which is prone to internal short circuit and thermal runaway, high requirements for cell early warning.

Facing the "pain point" at high altitude, Sunshine power EMS3000 has fully exerted the strongest "brain" function of energy storage system through a series of advanced technology applications, effectively overcoming the "high reverse".

In order to reduce the failure rate, this system is equipped with a new cell AI early warning technology to achieve cell early diagnosis, thermal out-of-control diagnosis, and internal short circuit diagnosis, avoiding cell "sick" jobs, effectively extending battery life, improve system efficiency.

In operation and maintenance, through the application of intelligent technologies such as site-level panoramic monitoring and fault alarm, it realizes remote local collaborative control, saves the manual station "diagnosis" link, and can design the operation and maintenance scheme in advance, improve O & M efficiency and facilitate O & M.

Site-level coordination,

help light storage coordination and stable operation of GWh power station

although the cost of EMS in an energy storage system is not high, it canAct as a smart "brain" of a power station ". Especially when the photovoltaic + energy storage comprehensive power station and GWh-level power station need strong operation strategies, the "super brain" of site-level coordinated management can ensure the stable and efficient operation of multiple types of complex power stations.

Taking this project of photovoltaic energy storage power station, which is located at 3700 high, as an example, Sunshine power EMS3000 not only breaks the pain points brought by the plateau, but also gives full play to the advantages of light storage collaborative control, according to the real-time operation status of photovoltaic/energy storage, the prediction results of power generation and the dispatching requirements of power grid, the optimal output of photovoltaic and energy storage can be optimized to make the integrated operation of optical storage system more efficient. In addition, it also has the auxiliary network construction functions such as fast dispatching of power grid, fast response of primary frequency modulation, dynamic voltage regulation, system peak regulation, black start, etc., and protects the stability of power grid in Tibetan areas.

In addition, the current GWh power station is accelerating into grid-connected operation. The energy storage system provider led by Sunshine power supply accelerates the exploration of the energy management system for data intercommunication between the stations, making GWh power station run smoothly.

Recently, Toge ruoge, Haixi, Qinghai province, built by Huadian (Haixi) New Energy Co., Ltd., shared the full capacity of the energy storage power station. The scale of the power station is 270MW/1080MWh, which is currently the largest single electrochemical energy storage power station in China and the largest intelligent shared energy storage project in high altitude areas. This project has put 51 units of solar power supply PowerTitan liquid cooling energy storage system into operation.

As a single-time project with the network exceeding 1GWh, the demonstration effect of internal coordination management in toge ruoge power station is obvious, which can help better solve the security and data "troubles" caused by over ten thousand cell ". On the one hand, thanks to the full-stack self-development of key equipment, the PowerTitan energy storage system has been pre-installed and coordinated before leaving the factory, and the equipment is connected to the grid upon arrival. On the other hand, GWh-level stations need to manage over 1 million cell and massive data, with numerous levels and complicated interfaces. The solar energy storage system realizes the data intercommunication between the internal BMS and EMS, and is highly intelligent and integrated to ensure the long-term stable operation of the power station.
