What are testing items and procedures?

Testing items and procedures, including type test, production test, installation evaluation, commissioning test at site, and periodic test, are provided in order to verify whether ESS applied in EPSs meet the safety and reliability requirements of the EPS.

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 are ESS performance specifications & test requirements?

ESS performance specifications and test requirements vary considerably depending on the location of deployment, size, and application. Key parameters include voltage, active power, reactive power, and energy. Additionally, the test labs create application-specific tests related to performance, safety, and environmental aspects.

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 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.
