What is a storage battery?

Storage batteries, also called photovoltaic batteries, are essential devices for energy storage, allowing the storage of electrical energy produced by renewable sources, such as photovoltaic panels, for later use.

Why do solar panels use batteries?

The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is supplied by the panels, and the excess is used to charge the batteries.

Can a Bess be used with a battery energy storage system?

Measurements of battery energy storage system in conjunction with the PV system. Even though a few additions have to be made, the standard IEC 61850 is suited for use with a BESS. Since they restrict neither operation nor communication with the battery, these modifications can be implemented in compliance with the standard.

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 .

What are the components of a battery system?

The system consists of three components: a control center, a PV system and a BESS. Depending on the PV system's output and supply forecast, the control center prompts the change of the incoming and charging power at the battery by transmitting the SetData and SetValues services.

What are the logical nodes of the battery system zbat & zbtc?

The logical nodes of the battery system ZBAT and the battery charger ZBTC are responsible for battery data. The node ZBAT contains general information on the battery, including battery type, capacity and charging (power injection). They can also be used to perform logical node tests and to switch the system on and off.

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.
