电能存储（EES）系统.第3-3部分:电能存储系统的规划和性能评估.能量密集型和备用电源应用的附加要求

[中文适用范围]： 本部分IEC 62933规定了在能源密集型、孤岛电网和备用电源应用中设计、控制和操作EES系统时的要求、指南和参考。在能源密集型应用中，EES系统为支持的电网或用户设备提供可变功率的长充电和放电阶段。在孤岛操作中，EES系统为孤岛电网提供能量，并协调孤岛电网中的其他发电系统。在备用电源和紧急支持中，当主电网电源不可用时，EES系统为内部电网或一组紧急负载提供能量。 [外文原描述]： IEC TS 62933-3-3:2022 provides requirements, guidelines and references when EES systems are designed, controlled and operated for energy intensive, islanded grid and backup power supply applications. In energy intensive applications, the EES system provides long charge and discharge phases at variable powers to the supported grid or user equipment. In islanded operation, the EES system provides energy to the islanded grid and coordinates other power generation systems in the islanded grid. In backup power supply and emergency support, the EES system provides energy to the internal grid or a set of emergency loads when the main grid power supply is not available.
