摘要:

场景生成是高可再生能源渗透电力系统运行和规划中的重要步骤。本文提出了一种基于生成对抗网络的数据驱动方法,该方法基于两个相互连接的深度神经网络。与基于概率模型的方法相比,我们的方法能够捕捉大量相关资源在时间和空间维度上的可再生能源生产模式。通过使用NREL集成数据集中的风能和太阳能时间序列数据进行验证,证明了所提方法能够生成具有多样行为的逼真风能和光伏发电曲线。此外,通过使用训练期间的标注数据,展示了如何根据不同感兴趣的条件生成场景。例如,可以基于天气事件(如高风日)或年份时间(如七月某日的太阳能发电)来生成场景。由于神经网络的前馈性质,无需复杂的采样技术即可高效生成场景。

英文摘要:

Scenario generation is an important step in the operation and planning of power systems with high renewable penetrations. In this work, we proposed a data-driven approach for scenario generation using generative adversarial networks, which is based on two interconnected deep neural networks. Compared with existing methods based on probabilistic models that are often hard to scale or sample from, our method is data-driven, and captures renewable energy production patterns in both temporal and spatial dimensions for a large number of correlated resources. For validation, we use wind and solar times-series data from NREL integration data sets. We demonstrate that the proposed method is able to generate realistic wind and photovoltaic power profiles with full diversity of behaviors. We also illustrate how to generate scenarios based on different conditions of interest by using labeled data during training. For example, scenarios can be conditioned on weather events~(e.g. high wind day) or time of the year~(e,g. solar generation for a day in July). Because of the feedforward nature of the neural networks, scenarios can be generated extremely efficiently without sophisticated sampling techniques.
