IEC 62933-3-1 ED1

Electrical energy storage (EES) systems - Part 3-1: Planning and performance assessment of electrical energy storage systems - General specification

Scope

IEC 62933-3-1:2025 is applicable to EES systems designed for grid-connected indoor or outdoor installation and operation. This document considers:
necessary functions and capabilities of EES systems; sizing and design of EES system; operation of EES system; test items and performance assessment methods for EES systems; requirements for monitoring and acquisition of EES system operating parameters; exchange of system information and control capabilities required; maintenance of EES system. Stakeholders of this document comprise personnel involved with EES systems, which include:
- planners of electric power systems and EES systems;
- owners of EES systems;
- operators of electric power systems and EES systems;
- constructors;
- suppliers of EES systems and its equipment;
- aggregators.
Use-case-specific technical documentation, including planning and installation specific tasks such as system design, monitoring, measurement, tests, operation and maintenance, are very important and can be found throughout this document.
NOTE This document has been written for AC grids, however parts can also apply to DC grids.
