10kv high voltage cabinet manual energy storage

What is a high-voltage energy storage system?

A high-voltage energy storage system (ESS) offers a short-term alternative to grid power, enabling consumers to avoid expensive peak power charges or supplement inadequate grid power during high-demand periods. These systems address the increasing gap between energy availability and demand due to the expansion of wind and solar energy generation.

How much energy does a high-voltage system provide?

Provides 28.2kWh to 112.8kWh of energy, easily meeting the electricity needs of small and medium-sized businesses. The high-voltage system delivers greater output power, offering more robust performance for loads.

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.

What is the peak value of transient overvoltage at LVDC?

The peak value of transient overvoltage at the LVDC side is about 720 V and overshoot is about 0.02%, and the peak value of transient overcurrent at the LVDC side is about 480 A and overshoot is about 68.4%, which is within the allowable range. Under the condition of 20% rated power, the output current THDi is 3.31%, as shown in Figure 8. Figure 7.

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.
