摘 要: 针对传统风电场景生成方法未充分利用风电功率的预测误差,以及未合理考虑风电序列时间相关性的问题,提出了一种基于LSTM-CGAN(LongShort-Term MemoryConditionalGenerativeAdversarialNetwork)的风电场景生成方法。该方法在条件生成对抗网络模型的训练过程中引入了符合风电预测误差分布的随机噪声,同时使用深度长短期记忆网络搭建条件生成对抗网络的生成器和判别器。算例结果表明,所提方法生成的场景集对风电真实场景的覆盖率能够保持在98%以上,刻画风电的不确定性也不会过于保守,能够更好地学习到风电序列的时间相关性。 |

Abstract: Addressing the issues that traditional wind power scenario generation methods do not fully utilize the prediction errors of wind power and do not adequately consider the temporal correlation of wind power sequences, this paper proposes a wind power scenario generation method based on Long Short-Term Memory Conditional Generative Adversarial Network (LSTM-CGAN). This method introduces random noise that conforms to the distribution of wind power prediction errors during the training process of the conditional generative adversarial network model, while employing deep Long Short-Term Memory networks to construct the generator and discriminator of the conditional generative adversarial network. The results of the case studies indicate that the scenario set generated by the proposed method maintains a coverage rate of over 98% for real wind power scenarios, and it effectively captures the uncertainty of wind power without being overly conservative, allowing for better learning of the temporal correlations in wind power sequences. |
