6 FAQs about [Voltage adaptability of energy storage power station]

What is the voltage range of energy storage power station?

The range of abnormal voltage is from 0 to 3.39 V, and the temperature range is from 22 to 28 °C. The current jump is caused by the switching between charging and discharging of the energy storage power station. The SOC ranges from 17.5 to 86.6%.

Why is I-VSG control a good choice for battery energy storage?

Due to the use of overdamping control, the system output power under the I-VSG control strategy does not overshoot, and its power change rate is smaller, as shown in Fig. 12d. So the requirement for battery energy storage margin is smaller.

Can energy storage battery improve output frequency performance of energy storage system?

The energy storage battery can maintain a safe working state at any time and be smoothly disconnected, which can effectively improve the output frequency performance of energy storage system. Simulation results further demonstrated the effectiveness of the VSG control theoretical analysis. Previousarticlein issue Nextarticlein issue VSG
