A TCN-based Hybrid Forecasting Framework for Hours-ahead Utility-scale PV Forecasting

no code implementations16 Nov 2021 Yiyan Li, Lidong Song, Si Zhang, Laura Kraus, Taylor Adcox, Roger Willardson, Abhishek Komandur, Ning Lu

The hybrid framework consists of two forecasting models: a physics-based trend forecasting (TF) model and a data-driven cloud-event forecasting (CF) model.

ProfileSR-GAN: A GAN based Super-Resolution Method for Generating High-Resolution Load Profiles

no code implementations18 Jul 2021 Lidong Song, Yiyan Li, Ning Lu

When training the ProfileSR-GAN generator network, to make the generated profiles more realistic, we introduce two new shape-related losses in addition to conventionally used content loss: adversarial loss and feature-matching loss.
