T/JES 005-2025 The technical requirements for configuring user-side energy storage systems in a new power system

Scope

Main technical content: The standard specifies the basic technical requirements for energy storage configuration in new power systems. Based on different scenarios of energy storage configuration and considering various configuration factors, a more reasonable configuration scheme is formed. The configuration factors that need to be considered in energy storage configuration include multiple aspects. In terms of capacity requirements, energy capacity configuration should consider peak regulation, renewable energy absorption, and backup power supply needs; power capacity configuration should consider frequency regulation, reactive power adjustment, and transient stability requirements; system performance requirements focus on charge and discharge efficiency, self-discharge characteristics, and cycle life, etc. Access system configuration requirements include access point selection, access voltage level, protection and control configuration, and communication and monitoring configuration. Energy storage system data analysis includes data collection and characteristic analysis. Data collection covers power system data and energy storage system data. Characteristic analysis involves technical characteristics, economic characteristics, and environmental characteristics. In terms of energy storage system configuration, energy capacity configuration is determined based on grid peak regulation, renewable energy absorption, and backup power supply needs; power capacity configuration is determined based on power system frequency regulation, fault clearance time, and reactive power requirements.
