ITEP 01-21 Master Thesis: Commissioning and operation of a battery storage system


Bereich

Abschlussarbeiten (Bachelor- und Masterarbeiten)

Tätigkeitsbeschreibung

The regulation of electric power utilities, advancement in technology, environmental concerns, and emerging power markets are leading to increased interconnection of distributed generators to the utility system. This is leading to the integration of a large number of distribution generation (DG) systems to utility network. Small DG systems based on battery storage systems with a capacity smaller than 20 kW are gaining popularity among private sector in the last few years due to their higher operating efficiencies and low initial cost. Especially the combination of battery storages and micro gas turbines is very interesting in the research sector.

The aim of the work is to commission and operate an existing battery storage system.

To provide a better insight into the expected content of the Master thesis project, requirements and expectations are listed in the following:

  • Read literature and summarize the state-of-art approaches for modelling a battery storages, in particular for lithium ion.
  • Implement a stable communication to operate the battery system.
  • Implement the selected model in a non-real-time simulation environment using MATLAB or MATLAB/Simulink.
  • Implement the same model in a real-time simulation environment such as RT-LAB or RTDS.
  • Validate the model with experimental results, using data provided by an operation of the battery storage (optional).
  • Make a clear and comprehensive presentation and evaluation of the results. All results should be documented adequately.
Persönliche Qualifikation

  • A background in electrical engineering is required for this project.
  • Experience in programing using MATLAB or simulations using MATLAB/Simulink is a plus.
  • Knowledge about power system simulations is a plus.

ITEP 02-21 Master Thesis: Network optimization using Superconducting Cables


Bereich

Abschlussarbeiten (Bachelor- und Masterarbeiten)

Tätigkeitsbeschreibung

Providing a reliable and secure power and energy system is one of the main challenges of the new era. The efficient operation of power systems contributes to decrease in fuel consumption and gas emission, conservation of natural resources, ensuring sustainability with better planning, and providing cleaner energy. The evolving modern optimization methods lead to more effective solutions and are promising for the continuously changing power system management, planning, and operation. New technologies based on superconducting materials are gaining popularity among private sector in the last few years due to their higher operating efficiencies. In special, superconducting cables are very interesting in the research sector. The integration of such technologies as well as a large number of distribution generation (DG) systems to utility network leads to the need for re-planning of the existing electrical systems. The aim of the work is to optimize an existing 110 kV network considering the inclusion of superconducting cables.

To provide a better insight into the expected content of the Master thesis project, requirements and expectations are listed in the following:

ITEP 03-21 Master Thesis: Identification of a real micro gas turbine based on Rowen´s model


Bereich

Abschlussarbeiten (Bachelor- und Masterarbeiten)

Tätigkeitsbeschreibung

The regulation of electric power utilities, advancement in technology, environmental concerns, and emerging power markets are leading to increased interconnection of distributed generators to the utility system. This is leading to the integration of a large number of distribution generation (DG) systems to utility network. Small DG systems based on micro turbine technology with a capacity smaller than 500 kW are gaining popularity among industry and utilities in the last few years due to their higher operating efficiencies, lower emission levels, and low initial cost. The micro turbine generation (MTG) systems are more reliable and lightweight, can operate with different fuels, and are proving to be a supplement to the traditional forms of power generation, whether it is stationary, mobile, remote, or interconnected with the utility applications.

The aim of the work is to validate the measurement values of our real micro gas turbine and the the simulated data form the Rowen model. Therefore, it is necessary to identify and extract the parameter which are used within the Rowen model and which are given from our real laboratory setup.
