PhD position - Data-Driven Distribution Models for Robust Design of Island Energy Systems with a High Share of Renewable Electricity

le contenu du travail

systems. Such systems are characterized by high spatial and temporal variability of energy supply and demand as well as by a high degree of interdependence of material and energy flows. Research at IEK-10 aims to provide scalable and real-time capable methods and tools which enable the energy-optimal, cost-efficient and safe design and operation of future energy systems.

Your Job

Your Tasks In Detail

Optimization-based design of future energy systems is subject to uncertainties that stem from the intermittent and non-dispatchable renewable electricity sources. Fluctuation in local renewable electricity supply usually can be balanced via grid connection. However, some systems, e.g., island systems, require robustness against the uncertainty in their electricity sources. Robust optimization techniques allow to arrive at robust system designs but rely on accurate distribution models for the uncertain data at hand. In particular, distribution models for uncertain time series like renewable electricity generation remain a largely unexplored field in robust design. The scope of this PhD project therefore is (i) to find efficient ways to model potentially correlated distributions using machine learning, particularly artificial neural networks (ANNs), and (ii) to utilize global optimization for robust sampling of the derived distribution models.

• Advance preliminary work on neural network-based distribution models for energy time series
• Combine machine learning with robust programming and global optimization
• Extend our in-house framework for energy systems optimization by efficient formulations and algorithms for design and operation of energy systems with embedded ANNs
