What is a SoC balancing control strategy for energy storage units?

A SOC balancing control strategy for energy storage units with a voltage balance function is proposed. An analysis of SOC trends is carried out in response to the power changing of loads and micro-source. An adaptive virtual resistances algorithm is coordinated with the control strategy of VB to accelerate the balance process.

Can a two-stage SoC balancing control technique improve SoC balance?

The suggested two-stage SOC balancing control technique is offered based on this. The method suggested in this paper can be used to estimate the difference in line resistance and enhance SOC balance, according to simulation findings.

How does SoC balancing affect power supply quality?

When VB is performs energy transmission, it changes the SOC deviation and increase the bus voltage unbalance, affecting the power supply quality of the bipolar DC microgrid. The SOC balancing power bridge plays a critical role in controlling the direction and duration time of SOC balancing for the batteries.

How does SoC balancing work?

This means keeping the work status unchanged for the battery with a larger SOC, while changing the work status for the battery with a smaller SOC to be opposite to that of the battery with a larger SOC, thereby increasing the speed of SOC balancing.

How does SoC affect droop control coefficient?

The energy of the DESS with greater SOC falls more quickly than that with lower SOC because the droop control coefficient of each converter is designed to be negatively associated with the SOC. As a result, the difference in SOC between DESSs gradually decreases until the load power is eventually distributed proportionally.

What EMS strategies are used for balancing SoC among Bess units?

In this article, we present a comprehensive review of EMS strategies for balancing SoC among BESS units, including centralized and decentralized control, multiagent systems, and other concepts, such as designing nonlinear strategies, optimal algorithms, and categorizing agents into clusters.
