GB/T 44134-2024Planning guide for electrochemical energy storage station in power system (English PDF)

Foreword

This document was issued on 28 May 2024 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 December 2024.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

1 Scope

GB/T 44134-2024 is the planning guide for siting and sizing electrochemical energy storage stations on the Chinese power system. China is building grid batteries faster than anyone, largely because provinces require new renewable capacity to be paired with storage, and the question the guide answers is the one those mandates skip: how much storage, of what duration, at which point on the system actually helps. The answer differs by connection point, which is how the standard is organised. It sets the general requirements and the analysis of system requirements, then the configuration principles and methods for storage on the generation side, on the grid side and on the user side, each with the services expected of it and the sizing that follows. It took effect on 1 December 2024.

This document specifies the system requirements analysis for electrochemical energy

storage station in power system, as well as the configuration principles and methods of

electrochemical energy storage station on the power supply side, grid side, and user

side.

This document applies to the planning and configuration of the electrochemical energy

storage station connected to power system at a voltage level of 10 (6) kV and above.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in DL/T 2528 and

the following apply.

3.1

electrochemical energy storage station

Energy storage station whose energy storage uses electrochemical energy storage media,

which mainly include: lithium-ion battery, lead-acid/lead-carbon battery, flow battery,

sodium-ion battery, sodium-sulfur battery, fuel cell, etc. Electrochemical energy storage

station is divided into three categories: power supply side, grid side, and user side

according to its access point location.

3.2

peak shaving

regulation resources, and demand-side response capabilities, and be determined in

combination with factors such as the construction conditions and construction period

of the energy storage project.

4.5 When the planning and implementation of the electrochemical energy storage

station differs significantly from expectations or there are major adjustments to the

energy and power plan, planning assessment and rolling adjustments shall be conducted.
