Creating Temporally Correlated High-Resolution Power Injection Profiles Using Physics-Aware GAN

arXiv.org Artificial Intelligence

Traditional smart meter measurements lack the granularity needed for real-time decision-making. To address this practical problem, we create a generative adversarial networks (GAN) model that enforces temporal consistency on its high-resolution outputs via hard inequality constraints using a convex optimization layer. A unique feature of our GAN model is that it is trained solely on slow timescale aggregated power information obtained from historical smart meter data. The results demonstrate that the model can successfully create minutely interval temporally-correlated instantaneous power injection profiles from 15-minute average power consumption information. This innovative approach, emphasizing inter-neuron constraints, offers a promising avenue for improved high-speed state estimation in distribution systems and enhances the applicability of data-driven solutions for monitoring such systems.


GAN are the days for NVIDIA

NVIDIA's model works better than the rest when it comes to customised prompts, due to the expert denoising system which trains denoisers to maintain fidelity to the textual prompt even in the later stage of the generation process. But, this is not the first time NVIDIA stepped into the waters of text-to-image modelling. Before coming up with eDiffi, NVIDIA used deep learning models to create versions of the GauGAN model. The second version of the model, released in November 2021, was trained on 10 million high-quality landscape images. The application demo allowed users to produce images based on any text input they provide. The GauGAN model is based on generative adversarial networks (GAN), unlike eDiffi, which uses diffusion modelling for generating images. So why did NVIDIA take a departure from using GAN for their text-to-image feature?

We already observe the importance and the ability of the artificial neural networks to do the intensive tasks particularly on the computer vision or the natural language processing fields in these recent years. However, it is known that far more researches still need to be implemented for the automations on human tasks via deep learning. For instances, we may ask ourselves is it possible for us to utilize deep learning to create something new or things that are not existed. Is it possible for us to use deep learning to generate or create artworks with similar styles but different contents by learning from the painter's past works? These tasks sound to be difficult but GANs make it possible!
