6 FAQs about [Energy storage system communication fault protection]

Can hybrid networks protect against fault currents in inverter-based systems?

Hybrid networks have different fault characteristics (AC, DC), harmonics, and bidirectional power flows, therefore, conventional schemes cannot deal the protection effectively. The significant reduction of fault currents during inverter-based systems has challenged the existing protection schemes.

Do STFT-based fault detection schemes protect hybrid AC/DC networks?

STFT-based fault detection schemes use high-frequency components of the transients of both AC and DC faults (Ukil et al., 2017). The successful results verify the applicability of DSP techniques to overcome the protection of hybrid AC/DC networks.

What are the NFPA standards for energy storage systems?

Two of the most notable standards in the United States are Underwriters Laboratories (UL) 9540 (Standard for Energy Storage Systems and Equipment) and National Fire Protection Association (NFPA) 855 (Standard for the Installation of Stationary Energy Storage Systems).

What are the disadvantages of MMC-switched fault protection schemes?

Fault protection schemes in MMC-switched categories have been reviewed (Wang et al., 2019). The drawback of the MMC scheme is that it is vulnerable to voltage stresses owing to overvoltage and overcurrent during faults. Fast protection and limiting devices are required to protect the MMC.

How to protect a distribution network using transient energy signals?

A modified MM scheme was used to protect the distribution network using transient energy signals and differentiate between positive and negative polarity (Shah et al., 2022). DSP schemes require high sampling frequency and computation time to overcome the transient nature of multiple DERs (PV, wind) and converter topologies in DC networks.

What are the guidelines for battery management systems in energy storage applications?

Guidelines under development include IEEE P2686 “Recommended Practice for Battery Management Systems in Energy Storage Applications” (set for balloting in 2022). This recommended practice includes information on the design, installation, and configuration of battery management systems (BMSs) in stationary applications.
