海上风电场各风电机组间存在较强的时空关联,现有风电功率预测研究虽对时空关联进行了探索,但未能更好地表达动态的空间关联;同时,空间关联的“黑盒”也降低了预测的可信度;另外,概率预测相比确定性预测可提供更全面的信息。为此,提出一种基于自适应图卷积网络(AGCN)-长短期记忆(LSTM)网络的海上风电场功率超短期概率预测模型。首先,通过AGCN中的自适应矩阵获取季节性变化海上风电机组间的动态空间关联,并实现空间维度的可解释,同时利用LSTM网络挖掘数据时间维度的相关性;其次,基于所获得的时空关联,通过改进的分位数回归模型构建风电场功率概率预测区间;最后,基于中国东海大桥海上风电场真实数据进行仿真验证。结果表明,相较于已有概率预测模型,动态图拓扑可以更好地揭示海上风电场变化的空间关系;改进后的分位数回归模型有效避免了分位数预测存在的曲线交叉问题;二者共同提升了模型整体预测精度和稳定性。
There are strong spatio-temporal correlations among the wind turbines in offshore wind farms. Although previous research on wind power prediction has explored the spatio-temporal correlation
its dynamic spatial correlation has not been better expressed. Meanwhile
the “black box” of spatial correlation significantly reduces the prediction credibility. In addition
the probability prediction provides more comprehensive information than deterministic prediction. Therefore
based on the adaptive graph convolutional network (AGCN) and long short-term memory (LSTM) network
an ultra-short-term probability prediction model of offshore wind farm power is proposed. Firstly
dynamic spatial correlations between seasonal offshore wind turbines are obtained through the adaptive matrix in AGCN
and interpretability in spatial dimensions is achieved. Meanwhile
the LSTM network is used to mine the temporal correlation of data. Secondly
based on the obtained spatio-temporal correlations
an improved quantile regression model is used to construct a probability prediction interval for wind farm power. Finally
based on the real data from the offshore wind farm of Donghai Bridge
China
simulation and verification are conducted. The results indicate that compared with existing probability prediction models
dynamic graph topology can better reveal the spatial relationship of changes in offshore wind farms. The improved quantile regression model effectively avoids the problem of curve crossing in quantile prediction. They both improve the overall prediction accuracy and stability of the model.
