Offshore wind generation time series for technology SP316 HH155 (PECD 2021 update)

This data (csv file) provides simulated hourly time series of offshore wind generation with specific power (SP) 316 W/m2 turbines at hub height (HH) of 155 m for the regions shown in the attached map. The analysed offshore wind power plants are sited at the best sites with max 100 km distance to shore, except for the far-offshore North Sea regions (the regions which do not have any connection to shore) where all locations are allowed. The map shows the resulting capacity factors (annual mean). The Excel file gives the average distance to shore for each individual region. Wake losses are modeled, with additional 5 % of other losses and unavailability considered. The time stamps are in GMT; the variable (column) names relate to the region names shown in the maps. The data include also country-level aggregations, e.g., UK00_OFF is the aggregated offshore wind generation of all the UK regions (weighted by regional installed capacities). The data are part of the variable renewable energy generation time series created for ENTSO-E in the 2021 update of the Pan-European Climate Database (PECD) dataset. ENTSO-E has used the data in ERAA 2021 and Winter Outlook 2021-2022 assessments, and they are used in TYNDP 2022. The simulations are carried out by DTU Wind Energy, with the future technology selection and data validation discussed and agreed with ENTSO-E and its members. The linked journal paper (1st link) describes the ERA5-based simulation methodology. It is requested that the paper is cited when the data are used. The linked related journal paper (2nd link) describes the modeling of wake losses for the offshore wind power plants and the storm shutdown behaviour (the smoothest storm shutdown technology is assumed).

本数据集为逗号分隔值（CSV）文件，包含附图所示区域内，轮毂高度（Hub Height，HH）为155米、单位扫风面积功率（Specific Power，SP）为316 W/m²的海上风机的模拟逐小时海上风电发电量时间序列。本次分析覆盖的海上风电场均选址于距岸距离不超过100公里的最优场址，但远海北海区域（即无任何岸线连通的区域）除外，此类区域可使用任意场址。附图展示了各区域的容量因子（年度平均值）计算结果。配套Excel文件提供了各单个区域的平均离岸距离。本数据集已计入尾流损耗，并额外考虑了5%的其他损耗与机组不可用率。时间戳采用格林尼治标准时间（GMT）；数据变量（列名）与附图中的区域名称一一对应。数据集还包含国家级聚合数据，例如UK00_OFF代表英国所有区域的海上风电发电量总和（按各区域装机容量加权计算）。本数据集是为欧洲输电系统运营商联盟（ENTSO-E）在2021年版《泛欧洲气候数据库（PECD）》更新中构建的可变可再生能源发电量时间序列的一部分。ENTSO-E已将该数据集应用于《ERAA 2021》与《2021-2022年冬季展望》评估报告，同时该数据集也被应用于《TYNDP 2022》。本模拟由丹麦技术大学风能研究所（DTU Wind Energy）完成，未来技术选型与数据验证工作已与ENTSO-E及其成员方共同讨论并达成一致。第一条关联期刊论文阐述了基于ERA5的模拟方法学，特此要求使用本数据集时需引用该论文。第二条关联期刊论文阐述了海上风电场尾流损耗建模与风暴停机行为（本研究假设采用最平滑的风暴停机技术）。本数据集属于更大规模的风电与光伏数据集合的一部分，数据集链接：https://doi.org/10.11583/DTU.c.5939581
