aFRR, Automatic Frequency Restoration Reserve, Energy Activated

**Currently, data is only available from November 13th onwards. We are working on retrieving historical data dating back to the implementation of the Picasso system in mid October** Activated aFRR, also called secondary reserve, is used to restore frequency to the normal band (49.9-50.1 Hz) after the primary regulation (FCR) has stabilised the frequency. The dataset shows the marginal price for activated aFRR. Find more information about aFRR Energy Activation and PICASSO [here](https://energinet.dk/electricity/system services/nordic-balancing-model/picasso/afrr-picasso/) N.B.: The data is continuously updated and includes data from the last 3 months. Therefore, data beyond this time frame is not included in the dataset and the field "Date From" should be disregarded, as it does not affect the dataset's content or validity. **Caution**: The price data differs from the PICASSO calculated prices. The prices published by Energinet take priority and should be used in all cases.**目前，本数据集仅可提供11月13日及之后的数据。我们正致力于回溯检索自10月中旬Picasso系统上线以来的历史数据。** 激活型自动频率恢复备用（aFRR, activated Frequency Restoration Reserve），亦称二次备用，用于在一次调频（FCR, Frequency Containment Reserve）稳定系统频率后，将频率恢复至正常区间（49.9-50.1 Hz）。本数据集收录激活型aFRR的边际电价。 有关aFRR能源激活与PICASSO系统的更多详情，请访问：https://energinet.dk/electricity/system services/nordic-balancing-model/picasso/afrr-picasso/ **注**：本数据集将持续更新，仅包含近3个月内的数据。因此，超出该时间范围的数据未被纳入本数据集，且"Date From"字段可忽略，该字段不会影响数据集的内容与有效性。 **注意**：本数据集的价格数据与PICASSO系统计算得出的价格存在差异。所有应用场景中，均应以Energinet发布的官方价格为准。
