10kv switch energy storage device

What are the benefits of 10 kV & 15 kV SiC MOSFETs?

The benefits of using these 10 kV and 15 kV SiC MOSFETs include simplifying from multilevel to two-level topology and removing the need for time-interleaving by improving the switching frequency from a few hundred Hz for Si based systems to ≥ 10 kHz for hard-switched SiC based systems.

Why are energy storage systems introduced in distributed systems?

Besides, energy storage systems are also introduced in distributed systems to stabilize the power output of renewable energy [22, 23]. The power electronic conversion system is the interface to connect the energy storage system with the power grid.

Does a 10 kV SiC MOSFET improve dynamic characteristics?

To demonstrate the high performance packaging design coupled with the superior dynamic characteristics of 10 kV SiC MOSFETs, the improvement in dynamic characteristics for a submodule can be seen in Figure 2, which illustrates the clamped inductive load test results for the module at Ω, 8 kV /28 A.

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.

What are shunt reactive power compensation devices?

Shunt reactive power compensation devices such as static var compensators (STATCOMs) can provide a continuous and precise leading or lagging reactive power to improve the voltage stability of the power system. By introducing the ZVS technique along with the SiC device, the whole system can be more compact and more efficient.

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.
