Power Electronics Group of Tallinn University of Technology invites qualified applicants to apply for a PostDoc position in Hardware Protection and Control of DC Microgrids.
The future of the energy sector is associated with the wide electrification of energy production, transportation, together with the wide use of renewable energy sources. Consequently, it will require extensive use of power electronic converters along with DC distribution for energy transmission and distribution.
Current trends and regulatory directives stipulate significant decrease in the energy consumption and carbon footprint of buildings. The residential DC microgrids (RDCμG) with on-site renewable energy generation and storage were proven as a promising technology needed to meet these targets. However, the lack of awareness, mature technologies, and market-ready power electronic systems still limit the wide adoption of RDCμGs.
Power Electronics Group is starting a project "Future-Proof Power Electronic Systems for Residential Microgrids." The main objective of this project is to make a breakthrough in the applied design of power electronic systems for RDCμG by the acquisition of cutting-edge knowledge in topologies, control, optimization, reliability, and lifetime extension methods.
Modern technological developments and regulatory restrictions are forcing a significant reduction in both the energy consumption of buildings and the carbon footprint. This goal can be achieved by DC microgrids of households with energy production and storage capacity. The wider deployment of these microgrids is currently limited by a lack of knowledge, mature technological solutions, and market-ready power electronic systems. The tasks of this project are to achieve a breakthrough in the research of these systems by developing new schematic solutions, control methods, multi-parameter optimization algorithms, and methods that increase the reliability and service life of the systems. We expect that new knowledge will contribute to the development of innovative cost-effective power electronics systems, commercialization, and the wider deployment of DC microgrids. All this, in turn, will help speed up the transition to high-energy, low-carbon buildings.
The successful candidate will conduct research in the field of protection and control of power electronic converters in DC microgrids. He/she will be expected to do much more laboratory works than simulation studies. The postdoc is also expected to be capable of building high-quality lab setups that could be tested in remote settings without constant supervision. The postdoc will work on the real implementation of hardware protection and control of residential DC microgrids according to the existing standards of voltages, safety, and wiring, such as Dutch standard NEN NPR 9090.
Candidates must have:
- Ph.D. degree in power electronics or closely related.
- Documented experience with research dissemination in high ranked (Q1) journals.
- Hands-on experience with converter design, realization, and laboratory testing.
- Team-work skills in addition to self-motivation and ability to work independently.
- Up-to-date knowledge of DC microgrid market trends, the latest in the sector, and new applications.
- Ability to put forward technical solutions to meet the needs of the research project.
- Good written and verbal communication skills in English.
Candidates must have experience and competences in most of the following fields:
- Grounding of equipment in DC microgrid.
- Protection devices for DC microgrids.
- Decentralized control of DC microgrids.
- Control of power electronics for residential applications such as PV module-level converters, battery energy storage, etc.
- Simulation of power systems and power electronics using PSIM or PLECS.
- Design of mixed-signal PCBs for power electronic converters with embedded control and measurement system.
- Programming of DSP and micro-controllers.
- Experience with fund-raising and/or industrial collaboration will be considered as merits.
Interested applicants should send their full academic CV in an email with a description of why their prior experience matches the needs of the given position.
