How does Bess work?

Like any energy source at a solar PV plant, BESS must be monitored and controlled. This is done by three systems: The Energy Management System (EMS) monitors grid demand and how the required energy can be transferred from the BESS. This is done through control logic.

How does a SCADA system communicate with a BMS?

The SCADA system typically communicates with the BMS directly to monitor battery readings. It may also be beneficial or required for the SCADA system to communicate with DC-DC converters, inverters, and auxiliary meters in order to properly control the BMS. 2. What information from the batteries is displayed on the HMI?

What is a Bess system?

However, whether installed as standalone systems or with PV, wind, or another generator, BESS systems have the same purpose—storing energy to discharge during times when the primary generator (e.g. sunlight, wind) is unavailable, insufficient, or less economical.

What is a SCADA system in a solar PV plant?

The Supervisory Control and Data Acquisition (SCADA) system communicates with and controls devices throughout the solar PV plant. It is the nerve center of the entire operation, and the means by which operators can monitor plant operations and send commands. It is also possible for the SCADA system to take on the role of the EMS.

How does a SCADA system work?

Key readings that are passed through from the batteries/stacks include SOC, current, voltage, and temperature, as well as a number of connected stacks and alarm indicators. If there's a problem with the batteries—such as overheating or a failure to charge properly—the SCADA system can alert plant operators via an alarm on the HMI.
