Inner Mongolia PV and storage 160MW/320MWh project passed grid-connected test

The 160MW/320MWh photovoltaic power storage project in Kubuqi, Inner Mongolia, has recently successfully passed the grid-connected test of the energy storage power station, marking a breakthrough in the project's integration into the grid. As the first photovoltaic power storage project in Inner Mongolia to integrate energy storage into up to 6 35KV busbars, it has extremely high requirements for the consistency, real-time performance and reliability of the entire energy storage system, aiming to ensure that the energy storage system can be safely and efficiently integrated into the grid.

Sermatec Energy has tailor-made 56 sets of 2.867MW/5.734MWh air-cooled energy storage container systems for this project. It has demonstrated a number of significant advantages in technology, and its coordination capabilities are particularly outstanding. The entire station uses the coordination controller developed by Sermatec Energy. , as the coordination center of 6 buses and 104 PCS, not only ensures that the power error of the entire energy storage system is less than 2%, but also ensures that the power error of each grid connection point is also less than 2%, fully demonstrating the high coordinated operation capability of the system.

In addition, its power regulation speed is eye-catching. The time from receiving the power command to the power execution of the six grid-connected points is less than 300ms, which is far lower than the national standard requirement of 3s. It is worth noting that the system also has an inertia support function, which can actively detect the rate of change of the grid-connected point frequency and compensate for load fluctuations by adjusting the active power of the energy storage system, thereby effectively reducing the fluctuation range of the system frequency and keeping the system within the normal operating range. In terms of technical specifications, all parameters of the project have reached the industry-leading level. The active control adjustment time of a single bus is less than 150ms, the active control adjustment time of 6 buses is less than 300ms, and the primary frequency regulation adjustment time and inertia support adjustment time are both less than 500ms. These technical parameters fully demonstrate the advancement and efficiency of the project.

The Sermatec Energy Management System has a wide range of application scenarios, and is suitable for shared energy storage power stations, photovoltaic power stations, wind power power stations and other fields. It has a very high promotion value: including ensuring access performance, coordinated operation capabilities and safety and stability with the power grid, ensuring that the energy storage system can operate safely under various working conditions without causing instability or damage to the power grid. At the same time, the system also ensures the efficiency and response speed of the energy storage system in actual power grid operation, and complies with national and industry technical standards and management specifications.

In addition to the Kubuqi photovoltaic distribution and storage project in Inner Mongolia, this system technology has also been successfully applied to many projects such as the 100MW/200MWh shared energy storage project in Fushan, Yantai, Shandong, and the 50MW/100MWh shared energy storage project in Jingneng Xiaoshan, both of which have achieved significant results. Effect.

The Kubuqi photovoltaic and energy storage project in Inner Mongolia has not only injected new vitality into the development of local new energy, but also provided valuable experience and demonstration for the application of energy storage technology in China and even the world. Today, this once yellow sand land has been rejuvenated and has become a "photovoltaic sea" of new energy. Sermatec Energy's energy storage system is like a stable "anchor", providing solid support for this "sea".
