Multivariate Scenario Generation of Day-Ahead Electricity Prices using Normalizing Flows

no code implementations23 Nov 2023 Hannes Hilger, Dirk Witthaut, Manuel Dahmen, Leonardo Rydin Gorjao, Julius Trebbien, Eike Cramer

Additionally, our analysis highlights how our improvements towards adaptations in changing regimes allow the normalizing flow to adapt to changing market conditions and enable continued sampling of high-quality day-ahead price scenarios.

Physics-inspired machine learning for power grid frequency modelling

no code implementations2 Nov 2022 Johannes Kruse, Eike Cramer, Benjamin Schäfer, Dirk Witthaut

Finally, we generate synthetic time series from the model, which successfully reproduce central characteristics of the grid frequency such as their heavy-tailed distribution.

Normalizing Flow-based Day-Ahead Wind Power Scenario Generation for Profitable and Reliable Delivery Commitments by Wind Farm Operators

no code implementations5 Apr 2022 Eike Cramer, Leonard Paeleke, Alexander Mitsos, Manuel Dahmen

We present a specialized scenario generation method that utilizes forecast information to generate scenarios for day-ahead scheduling problems.

Nonlinear Isometric Manifold Learning for Injective Normalizing Flows

no code implementations8 Mar 2022 Eike Cramer, Felix Rauh, Alexander Mitsos, Raúl Tempone, Manuel Dahmen

To model manifold data using normalizing flows, we employ isometric autoencoders to design embeddings with explicit inverses that do not distort the probability distribution.

Validation Methods for Energy Time Series Scenarios from Deep Generative Models

no code implementations27 Oct 2021 Eike Cramer, Leonardo Rydin Gorjão, Alexander Mitsos, Benjamin Schäfer, Dirk Witthaut, Manuel Dahmen

The design and operation of modern energy systems are heavily influenced by time-dependent and uncertain parameters, e. g., renewable electricity generation, load-demand, and electricity prices.

Principal Component Density Estimation for Scenario Generation Using Normalizing Flows

no code implementations21 Apr 2021 Eike Cramer, Alexander Mitsos, Raul Tempone, Manuel Dahmen

We train the resulting principal component flow (PCF) on data of PV and wind power generation as well as load demand in Germany in the years 2013 to 2015.
