Field communication energy storage box

What does field do?

At Field, we’re accelerating the build out of renewable energy infrastructure to reach net zero. We are starting with battery storage, storing up energy for when it’s needed most to create a more reliable, flexible and greener grid. We're developing, building and optimising a network of big batteries supplying the grid.

When can large quantities of electricity be stored and retrieved?

Large quantities of generated electricity can be stored and retrieved anytime too little power is produced . Such a scenario can only be implemented when data is exchanged properly among a BESS, PV system and control system .

Is a battery energy storage system a state-of-the-art protocol?

Communication with a battery energy storage system or BESS that is compliant with this protocol is not yet state-of-the-art but will be necessary in the future , , .

Why should you use a field Gerrards Cross battery?

Batteries like Field Gerrards Cross can ease grid constraints and reduce reliance on carbon-intensive forms of generation, such as gas, by charging up when renewable electricity supplies are abundant and discharging during peak demand. They’re also a proven, effective technology which helps reduce the cost of energy for bill payers.

What are fieldbuses used for?

Fieldbuses are used for digital transmission of communication between a control unit and different measuring sensors or actuators. Normally, the master-slave model is used, the control unit being the “master” and the different field devices the “slaves” .

How does the control center communicate with the PV system?

The control center communicates with the PV system by a Modbus protocol and with the BESS by IEC 61850. The IEC 61850 data structures provided by the BESS were created beforehand by a configuration file. Fig. 5 presents a schematic of this structure. Fig. 5. use case “meeting the supply forecast”. 5.1.
