Energy storage pcs detection and testing system

What are energy storage systems?

Energy storage systems (ESSs), and particularly battery energy storage systems, are finding their way into a very wide range of applications for utilities, commercial, industrial, military and residential power. Applications include renewable integration, frequency regulation, critical backup power, peak shaving, load leveling, and more.

What is DTE Energy CES testing?

The testing is being performed for DTE Energy as part of the US Department of Energy’s Energy Storage Smart Grid Demonstration Program. The CES consists of a power conditioning system, and a battery energy storage unit. Testing may include basic operation, round-trip efficiency, peak shaving, and frequency regulation.

What are the different types of energy storage technologies?

Chemistries range from Li-Ion, NiMH, NaNiCl, NaS, ZnO, Na+, and PbSO4; and technologies range from standard to flow, metal, and super-capacitors. Practical difficulties with testing such a wide range of energy storage technologies include the wide range of applications, measurements, electrical connectivity, and digital communication protocols.

What is an ESS dac system?

The ESS DAC system must perform comprehensive ESS characterization as well as application testing in a lab environment, and must also be rugged and transportable for the field. The system is required to perform all of the power grid, system, battery, inverter, load, and ambient measurements summarized in Figure 1.

What is an ESS & how does it work?

Some ESSs are designed to power a load over long durations, while others maximize energy, response time, and charge/discharge rates. ESSs range from less than 1kW to several MW in scale. Chemistries range from Li-Ion, NiMH, NaNiCl, NaS, ZnO, Na+, and PbSO4; and technologies range from standard to flow, metal, and super-capacitors.

How can the operator control the ESS master controller & battery management system (BMS)?

The operator can monitor and control the ESS master controller and battery management system (BMS) through optional communications, which support controller area network (CAN), Modbus, and Ethernet protocols.
