标准摘要
[中文适用范围]： 本部分为IEC 62933的技术报告，研究了电压等级在20 kV及以下的电动汽车(EV)充电站中配备光伏(PV)发电的电力储能(EES)系统(PV-EES-EV充电站)的案例。EES系统因其能使充电站(尤其是大功率快充站)对电网友好、提高清洁能源发电的自消纳率、增加充电站收益等优势而成为理想选择。在该应用中，EES系统通过多种运行模式(如削峰填谷、功率平滑、负荷跟踪、分时电价套利和辅助服务等)展现了卓越性能。基于对EES系统运行特性的总结，本文件给出了通用工作循环建议。 本文件包含以下内容： - PV-EES-EV充电站概述 - 典型项目案例中EES系统的运行分析 - EES系统运行模式的总结与建议 [外文原描述]： IEC TR 62933-2-200:2021(E) presents a case study of electrical energy storage (EES) systems located in electric vehicle (EV) charging stations with photovoltaic (PV) power generation (PV-EES-EV charging stations) with a voltage level of 20 kV and below. EES systems are highlighted in this document because they are a desired option to make the charging stations (especially the high-power fast charging stations) grid-friendly, improve the self-consumption of clean energy generation, and increase the revenue of stations. In this application, EES systems show excellent performance by running in a variety of available operating modes, such as peak shaving, power smoothing, load tracing, time-of-use (TOU) price arbitrage, and ancillary services. The general duty cycle is recommended based on the summary of the operation characteristics of the EES systems.
