Technical guide for black-start of electrochemical energy storage
1 Scope
This document specifies the general requirements and technical conditions for black-start of electrochemical energy storage, as well as the black-start technical requirements for black-start preparation, self-start, start of power generating equipment, and restoration of black-start power supply of the substation.
This document is applicable to the planning, design, test and operation of electrochemical energy storage systems or stations which have black-start capability and may be served as black-start power supply.

GB 51048 Design code for electrochemical energy storage station
DL/T 2528 Basic terms of electric energy storage
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
black-start of electrochemical energy storage
process of starting the connected power generation equipment or restoring the power supply of the substation equipment by means of the electrochemical energy storage system or station with black-start capability in the power system after a large-scale power outage without the support of an external power source
3.2
black-start time
time from the loss of working power and standby power at a power generating equipment or substation to the time when the power generating equipment or substation is able to restore power to the point of connection
4 General requirements
4.1 According to the point of connection, start object and path of the electrochemical energy storage system or station, the black-start of electrochemical energy storage may be divided into two types: starting the power generation equipment and restoring the black-start power supply of the substation. See Annex A for the typical black-start mode.
4.2 The planning and deployment for black-start of electrochemical energy storage system or station shall be linked to the layout and path planning of their black-start power supply connected to the grid.
