Probabilistic prosumer side flexibilities for multi use-case applications

Summary

The electric energy demand of buildings is increasing due to the electrification of the transportation and heating systems. While this puts an additional strain on the power grid, EVs and heat pumps (among others) are flexible loads that can be leveraged to keep the balance between generation and load. Coincidently, smart meters and edge computing resources (i.e. building automation systems) are deployed providing the means to access this flexibility. Hence, in this project, we will leverage building data to develop detailed models for the quantification and usage of flexibility at the building level for different time scales.

Design and Pricing of Ancillary Services in Stochastic Energy Systems

Summary

The provision of ancillary services is an important aspect to ensure the stability and the functioning of the electric power system, even more so in a system with increasing levels of renewable generation. However, the type of ancillary services and how they are being compensated likely needs to be adjusted from the current practice, which was designed for highly centralized energy production and inflexible demand. In this project, we will identify the type of services needed, how the capabilities of the individual resources can optimally be used and how they should be remunerated for their services.

Ancillary Services Provision in Power Systems with High Shares of Renewable Energy Sources

Summary

With the replacement of synchronous machine based generation by power electronics connected renewable generators, the speed of frequency dynamics increases and new voltage issues arise in distribution systems due to decreased system inertia and the distributed nature of these resources. In this project, we focus on the provision of ancillary services by distributed energy resources (DER) at different time scales. This entails Fast Frequency Control provided by grid-forming Voltage Source Converters and at the slower time scale, the integration of active distribution grids in a set of ancillary services.

Scalable market mechanisms for deploying massive amounts of distributed energy resources

Summary

We study how flexible devices, consumers and producers can participate in an automated fashion in an energy market that yields efficient market outcomes. As the availability of distributed resources in terms of production and flexibility is uncertain, probabilistic approaches for the automated bidding but also for the determination of the required reserves are necessary. Given that distributions of the willingness of the participants to accept prices are unknown, we intend to formulate and explore distributionally robust optimization models.

Intrusion detection and dynamic state estimation for power networks

Summary

State Estimation is an important tool in the Energy Management systems of electric power systems to monitor the state of the system. It takes measurements from the field and usually by the means of weighted least square optimization identifies the most likely system state. This step is necessary as measurements are subject to measurement errors. Traditionally, the resulting problem formulation includes the non-linear power flow equations. However, in previous work, we have derived a formulation that allows for a linear representation exhibiting the same accuracy but clearly superior computational performance to the non-linear approaches. In this project, we propose to explore how such linear formulation provides computationally efficient means to identify and filter false data injection (FDI) attacks. Protecting the power system against FDI attacks is of critical importance as many control functionalities rely on the reported state of the system.
