FAQS about Soc feedback control of energy storage

Is a VSG adaptive control strategy based on SoC feedback?

To sum up, a VSG adaptive control strategy considering SOC feedback of energy storage battery is proposed. Firstly, this paper lists physical constraints based on the energy storage side, thus given VSG’s inertia, output power and change rate of the power have corresponding value ranges.

What is SOC in energy storage?

Generally, the residual power of the energy storage unit is represented by SOC. The maximum capacity of a fully charged battery is SCN, define SOC0as the initial SOC when the energy storage converter starts to work, then the instantaneous charging and discharging current is defined as i(t), the expression of SOC is as follows:

What is energy storage based on virtual synchronous control?

Energy storage systems based on virtual synchronous control provide virtual inertia to the power system to stabilize the frequency of the grid while smoothing out system power fluctuations, and the constraining effect of the energy storage state of charge (SOC) has a significant impact on regulating virtual inertia and damping.

Can a SoC feedback-based adaptive control speed up frequency recovery?

The literature (Xia et al., 2018) proposes a SOC feedback-based adaptive control as a way to speed up frequency recovery, but excessive frequency deviations may destabilize the system.

What is energy storage control strategy?

This control strategy sacrifices the dynamic regulation performance of the energy storage converter, thus ensuring the overall dynamic response capability of the whole energy storage system. Therefore, the energy storage battery will not have over-discharge and other adverse phenomena, which protects the safety and service life of the battery.

Why is energy storage important in VSG control?

Since energy storage is an important physical basis for realizing the inertia and damping characteristics in VSG control, energy storage constraints of the physical characteristics on the system control parameters are analyzed to provide a basis for the system parameter tuning.
