10kv energy storage

Why is energy storage technology important in China?

Energy storage technology has become critical for supporting China’s large-scale access to renewable energy. As the interface between the battery energy storage system (BESS) and power grid, the stability of the PCS (power conversion system) plays an essential role.

What are the simulation parameters of energy storage PCs System?

Table 1. Simulation parameters. Among them, the rated voltage of the power grid is 10 kV and the frequency is 50 Hz. The HVAC part of the energy storage PCS system contains 15 modules in each phase, with a three-phase Y-connection.

Is large-scale energy storage a good idea?

Large-scale energy storage is favorable currently. The capacity expansion needs to be realized by the parallel connection of multiple low-voltage small-capacity PCSs and connected to a medium- or high-voltage power grid through the transformer. The connection would lead to the problems of low efficiency, high cost and unnecessary land occupation.

Why is energy storage important?

Energy storage can solve the power grid’s requirements of transient stability and short-term power balance and can be used for long-term power regulation. It can effectively deal with the systemic peak valley regulation and blocking of transmission and distribution lines [ 1, 2 ].

What is BYD energy storage?

With advanced lithium battery technology, BYD aims to promote the global transition from fossil energy to clean energy. 比亚迪储能新官网将于2023年5月19日迎来上线。 本次更新的内容包括官网样式布局，模块内容等。 给您造成的不便之处，还请谅解，谢谢！ the new official website of BYD Energy storage will be launched on May 19, 2023.

How many kV is a PCs module?

The source drain voltage of the device is V ds = 1.2 kV, and 15 modules are used for each phase in series for 18 kV, meeting the insulation requirements of the 10 kV voltage level. The rated capacity of each module is 23.8 kW, and the rated through current is about 34 A, with a sufficient through current margin. Figure 15. PCS prototype.
