T/JES 016-2026 Technical specifications for condition monitoring of electrochemical energy storage power stations participating in grid ancillary services

Scope

This standard specifies the technical requirements for state monitoring of electrochemical energy storage power stations operating in grid-connected mode, and their participation in ancillary services such as grid peak shaving and frequency regulation. It covers core content including basic definitions, technical indicators, evaluation systems, and ancillary service requirements, providing a unified technical basis for power station operation management and grid coordinated dispatching. The main technical content is as follows: (1) Clarify the access and equipment standards for energy storage power stations, evaluate their observability, controllability, and sustainable service capabilities, and set standards for the overall availability of energy storage power stations meeting the grid's ancillary service resource demands. (2) Establish an energy storage power station operation status indicator system, dividing monitoring content into battery management systems, energy storage converters, power distribution and conversion equipment systems, and auxiliary systems; specify the content and testing methods of grid-connected status parameters; clarify the definitions, statistical methods, and calculation methods of electrical performance indicators, energy efficiency indicators, and reliability indicators. (3) Establish a multi-dimensional evaluation mechanism. The monitoring system issues three levels of alerts based on the severity of the alarm; grid-connected status is divided into three levels, with clear grading criteria for power control and power quality parameters; electrical performance is evaluated using a weighted scoring system based on three dimensions: energy throughput and contribution, ancillary service capacity, and operation efficiency and utilization level; energy efficiency is evaluated using a weighted scoring system based on five dimensions: energy efficiency of the power station, transformer loss rate, energy retention rate, power consumption o
