What is energy storage performance testing?
Performance testing is a critical component of safe and reliable deployment of energy storage systems on the electric power grid. Specific performance tests can be applied to individual battery cells or to integrated energy storage systems.
How are PV storage systems tested?
Laboratory tests were conducted by independent testing institutes in accordance with the "Efficiency Guideline for PV Storage Systems” (version 2.0). To each analyzed system a system abbreviation (e.g. A1) was assigned. The batteries of the AC-coupled systems A1 to B2 are equipped with battery inverters.
How do integrated system tests measure energy storage performance?
Integrated system tests are applied uniformly across energy storage technologies to yield performance data. Duty-cycle testing can produce data on application-specific performance of energy storage systems. This chapter reviewed a range of duty-cycle tests intended to measure performance of energy storage supplying grid services.
Which batteries are equipped with battery inverters?
The batteries of the AC-coupled systems A1 to B2 are equipped with battery inverters. The DC-coupled systems B3 to I2 have so called hybrid inverters. Details about the methodology can be found in the Energy Storage Inspection 2018 and 2021.
