What is a grid-scale Bess?

... grid-scale BESS consists of a battery bank, control system, power electronics interface for ac-dc power conversion, protec- tive circuitry, and a transformer to convert the BESS output to the transmission or distribution system voltage level. The one-line diagram of a simple BESS is shown in Fig. 2.

Can a Bess be connected to an LV network?

When connecting to an LV network, the BESS can be treated similar to a generator incomer, though energy flow will be bi-directional. Depending on the AC drive configuration, it may be possible to connect the BESS directly to the network before the output is modulating, and have the drive perform a ‘ flying synchronisation ’.

Can a Bess connect to a LV or MV connection point?

If the BESS shall connect to a LV or MV connection point. Most battery systems will not exceed 1500 V DC, as this would bring them into the HV classification range and entail increased equipment and operational demands. Additionally, it may be difficult to find DC switchgear rated to such high voltages and current.

What type of connection should a Bess use?

The type of connection should be decided early. If the BESS shall connect to a LV or MV connection point. Most battery systems will not exceed 1500 V DC, as this would bring them into the HV classification range and entail increased equipment and operational demands.

Should a Bess be split into two or more distinct units?

It may be decided to split the BESS into two or more distinct units for connection at multiple points in the network. This can be done to allow multiple sections to function independently with BESS support, as well as provide redundancy in system design. The type of connection should be decided early.
