Modern N-1: Estimating power systems' resilience w.r.t. a hacked HVDC line

Ansprechpartner: Johannes Börner, Frühester Beginn: sofort

Classical N-1 considers the random outage of any component in the power system. It guarantees that the system still runs smoothly in that case. What we call modern N-1 should also consider the intended misbehavior of any component. This is of ever greater importance as system become more and more digitalized and cyber attacks more common and professional. Of special importance for the power system ar HVDC lines due to their large capacity and their ability for fast and well-controllable dynamics.
The thesis should examine the different effects that a successful hacker of the controller of an HVDC line could produce. The thesis should work on a qualitative level and survey potential attack directions. It should also simulate the effects in a high time-resolution simulation of an exemplary two zone power system connected via an HVDC link. Of interest are both short term distortions such as (partial) blackouts but also the destruction of the underlying hardware, as this would have long term dangerous consequences.
The thesis should conclude with first indications how the most detrimental effects could be avoided.

Probabilistic modeling of e-car charging

Ansprechpartner: Tim Janke, Frühester Beginn: sofort

Based on empirical data from an e-car charging station, the target is to develop and fit a probabilistic model for the power consumption of such a station. The model should be able describe both today's charging behavior as well as future situations, when the c-car density can be assumed to be much higher.
The intented use of such models is in energy management. Stochastic optimization routines can schedule flexible generation & consumption in accordance with the current and predicted charging demand. A description of the variance of the charging demand also gives rise to system optimization, i.e. determining how many charging stations to combine or which electrical flexibility options to integrate to offset varaibility. First steps in this directions should be undertaken.

Reconstructing Power Wholesale Market Prices from Operational Data

Ansprechpartner: Christopher Ripp, Frühester Beginn: sofort

This project aims at understanding in detail how prices at the day-ahead power markets arise, given the technical behavior of all relevant participants is known. This in an important ingredient for modeling future power systems and thus optimizing the course of the Energiewende.
Since 2016 the operational schedules of all large power plants in Europe are published on an hourly basis. Given their cost structure and a description of the demand and the renewable infeed it should then be possible to explain the observed power market prices. A straight-forward approach to this problem, however, does not yield satisfying results, an important factor being that it is not clear how to distribute long-term cost components onto individual hours.
The project will test and develop different models how to derive the true market prices given the real operation and fixed cost parameters for each power plant.

Evaluation of suitable communication protocolls for energy monitoring

Ansprechpartner: Christopher Ripp, Frühester Beginn: sofort

Energy data acquisition is an essential component of the digitization of energy systems in order to realize the required transparency. The measurement technology for the measuring the current and voltage values, etc. has been established for decades. For current applications in the field of the digitization of energy systems, therefore, the communication technology of the measuring equipment is an essential aspect. The M-Bus system, which has now been in use for more than 20 years, reaches the limits of the temporally necessary resolution of 1s due to its protocol structure and limited bandwidth. New communication protocols, however, such as modbus TCP or Bacnet can provide this resolution. The protocol telegrams are send via Ethernet, wrapped in an IP Layer.
Scope of this project seminar is to define the specific benefits and drawbacks of using modbus TCP or Bacnet. Therefore, the student has first to set up a test system with a measuring unit, which is compatible to modbus TCP and Bacnet (see picture). Second, programming a communication interface to get and visualize the data from the measurement unit.

This results will be used to build a comprehensive energy monitoring on Campus Lichtwiese for the development of a digital twin of the energy system.
