随着电动船舶的发展和普及,内河流域的港口用能结构正逐步由燃油转变为清洁的电能,港口负荷将对配电网峰谷差造成显著影响。为准确描述电动船舶充电负荷特征,提出了一种基于改进鲁棒性辅助分类生成对抗网络(RAC-GAN)的电动船舶充电负荷场景生成方法。首先,分析电动船舶充电负荷的特征,构建含环境特征与充电负荷的原始数据集;然后,对RAC-GAN进行改进,加入变分编码器对船舶数据集进行降维,抽取特征信息簇标签,并在判别器中引入噪声过渡模型和卷积层,以提高判别器的抗噪能力,并对网络的损失函数进行重定义;最后,以中国实际港口为例,基于改进的RAC-GAN生成船舶充电负荷的海量场景。仿真结果表明,所提方法能够学习到电动船舶的负荷特征,对噪声具有较高的鲁棒性,并且可以有效生成大量满足真实样本概率分布特征的电动船舶充电负荷场景。
With the development and popularization of electric ships
the energy structure of ports in inland river basins is gradually changing from fuel oil to clean electric energy
and the port loads will significantly impact the peak-to-valley difference of the distribution network. To accurately characterize the charging loads of electric ships
a scenario generation method for electric ship charging loads based on the improved robust auxiliary classifier generation adversarial network (RAC-GAN) is proposed. First
the characteristics of electric ship charging loads are analyzed
and the original dataset containing environmental characteristics and charging loads is constructed. Then
the RAC-GAN is improved by adding a variational encoder to reduce the dimensionality of the ship dataset
extracting the feature information cluster labels
and introducing a noise transition model and a convolutional layer to improve the resistance to noise for the discriminator
and the loss function of the network is redefined. Finally
taking an actual port in China as a case
massive scenarios of ship charging loads are generated based on the improved RAC-GAN. Simulation results show that the proposed method can learn the load characteristics of electric ships
has high robustness to noise
and can effectively develop many electric ship charging load scenarios that satisfy the probability distribution characteristics of actual samples.
