台风气象下电网负荷将会出现剧烈波动且威胁到电网安全稳定运行,亟需一种有效的方法来生成相应的负荷需求场景。文中提出一种面向稀少历史样本、基于可解释性条件生成对抗网络(CGAN)的台风负荷场景生成方法。首先,对历史台风负荷进行修正,并根据台风登陆位置、等级等信息对其进行标签分类。然后,提出一种两阶段数据扩充策略以应对数据匮乏问题,第1阶段利用历史台风日负荷序列之间的横纵向相关性信息进行样本扩充,第2阶段利用台风日与非台风日负荷之间的残差信息进一步进行样本扩充。最后,提出基于特征影响指标的CGAN因果解释方法,刻画了不同特征对于模型结果的调控力度大小。算例证实了文中所提模型及方法的有效性和先进性。
Under typhoon meteorology
the load of the power grid will experience severe fluctuations
posing a threat to the safe and stable operation of the power grid. An effective method is urgently needed to generate corresponding load demand scenarios. A typhoon load scenario generation method is proposed based on interpretability conditional generative adversarial network (CGAN) for rare historical samples. First
the historical typhoon load is adjusted and classified based on the information such as typhoon landfall locations and levels. Then
a two-stage data augmentation strategy is proposed to address the issue of data scarcity. The first stage utilizes the horizontal and vertical correlation information between historical typhoon daily load sequences for sample augmentation
while the second stage utilizes the residual information between typhoon and non-typhoon daily loads for further sample augmentation. Finally
a CGAN causal interpretation method based on feature influence indicators is proposed
which characterizes the regulation degree of different features on the model results. Numerical cases show that the proposed model and method are effective and progressive.
