电能存储（EES）系统.第3-2部分:电能存储系统的规划和性能评估.电力密集型和可再生能源集成相关应用的附加要求

[中文适用范围]： 电气能量存储 (EES) 系统 - 第 3-2 部分：电气能量存储系统的规划和性能评估 - 高功率和可再生能源集成相关应用的附加要求 [外文原描述]： IEC TS 62933-3-2:2023 provides the requirements for power intensive and renewable energy sources integration related applications of EES systems, including grid integration, performance indicators, sizing and planning, operation and control, monitoring and maintenance. The power intensive applications of EES systems are usually used to improve the dynamic performance of the grid by discharging or charging based on corresponding control strategies. The renewable energy sources integration related applications of EES systems are usually used to mitigate short-term fluctuation and/or to keep long-term stability. This document includes the following applications of EES systems: – frequency regulation/support; – grid voltage support (Q(U)) (“volt/var support”); – voltage sag mitigation; – renewable energy sources integration related applications; – power oscillation damping (POD).
