DIN IEC/TS 62933-2-2 VDE V 0520-933-2-2:2025-01

Considering the wide variety of applications of EES systems, it is becoming important to define the typical application of each EES system depending on its purpose and control types, and also important to define the corresponding performance testing methods and procedures of the EES system.
IEC 62933-2-1 Ed.1 describes the general specification of unit parameters and testing methods for EES systems, in which details of duty cycles for typical grid applications and the associated performance metrics and testing methods are not covered.
This part of IEC 62933 focuses on developing generic duty cycles for applications, identifying relevant performance metrics and developing performance testing methods and procedures for EES systems. The energy storage devices and technologies are outside the scope of this document.
This document defines a method to validate the EES technical specification for the manufacturers, designers, operators, utilities and owners of the EES systems who need to evaluate the performance of the EES systems for various applications. The following items are covered in this document:
- application
- performance testing methods
- duty cycles for specific application
This document should be used as a reference when selecting testing items and their corresponding evaluation methods.
This document considers applications such as:
- Frequency regulation
- Primary/Secondary/Tertiary frequency control
- Islanded grid
- Fluctuation reduction of PV and Wind Farm
- Reactive-power voltage control
- Renewables (PV) firming
- Power quality events mitigation
- Peak shaving
- Renewable (PV) firming
- Back-up power
