摘要:

在电力系统规划和安全评估中,尤其是在历史数据不足的情况下,具有相似分布和相关性的发电系统状态是必不可少的。在本文中,我们描述了一个生成模型的工业和商业客户的负载配置文件,基于条件变分自编码器(CVAE)神经网络架构,这是具有挑战性的,由于高度可变的性质,这样的配置文件。生成的上下文负载配置文件以一年中的月份和与电网的典型功率交换为条件。此外,代的质量进行了视觉和统计评估。实验结果表明,我们提出的CVAE模型可以捕捉历史负荷曲线的时间特征,并生成“现实”的数据,具有令人满意的单变量分布和多变量依赖关系。

英文摘要:

Generating power system states that have similar distribution and dependency to the historical ones is essential for the tasks of system planning and security assessment, especially when the historical data is insufficient. In this paper, we described a generative model for load profiles of industrial and commercial customers, based on the conditional variational autoencoder (CVAE) neural network architecture, which is challenging due to the highly variable nature of such profiles. Generated contextual load profiles were conditioned on the month of the year and typical power exchange with the grid. Moreover, the quality of generations was both visually and statistically evaluated. The experimental results demonstrate our proposed CVAE model can capture temporal features of historical load profiles and generate `realistic' data with satisfying univariate distributions and multivariate dependencies.
