Dr. Balog gives an IEEE Power Electronics Society Distinguished Lecture at the Dallas/Fort Worth chapter of the IEEE Power Electronics Society

As part of the IEEE Power Electronics Distinguished Lecture Series, Professor Balog, REAPERlab Director, gave a talk to the Dallas / Fort Worth chapter of the IEEE Power Electronics Society. Dr. Balog spoke about challenge in making photovoltaic (solar) energy affordable including that balance of systems costs and emerging regulations.

Dr. Balog wishes to thank Dr. Pradeep Shenoy of Texas Instruments and the Dallas Power Electronics Society for organizing and hosting the lecture.

Dr. Balog presented a paper at the International Conference on Photovoltaic Science and Technologies (PVCon) in Ankara, TURKEY

REAPER lab Director Dr. Robert S. Balog presented a paper entitled “D-STATCOM for a Distribution Network with Distributed PV Generation” at the 2018 International Conference on Photovoltaic Science and Technologies (PVCon) in Ankara, TURKEY / July 6, 2018.

This paper discussed the use of a distribution static synchronous compensator (D-STATCOM) for harmonic power compensation in a distribution network. Power quality in an AC power distribution system is reduced by nonlinear loads which draw non-sinusoidal current. When this distorted current interacts with the line impedance of the distribution network (the grid), the system voltage becomes distorted which could adversely affect other electrical devices connected to the grid. Compensating the harmonic current at the grid-edge improves the overall reliability of the electrical grid.

Muhammed Ekin presented a paper at the International Conference on Photovoltaic Science and Technologies (PVCon) in Ankara, TURKEY

Graduate student Mr. Muhammed Ekin presented a paper entitled “Reliability Assessment of Single-phase Module-Integrated Power Electronics Based on the Thermal Modeling of Photovoltaic Modules” at the 2018 International Conference on Photovoltaic Science and Technologies (PVCon) in Ankara, TURKEY / July 4, 2018.

The reliability of power electronics is important for photovoltaic (PV) systems as the cost of failure has a significant effect on the return on investment (ROI). This paper developed a thermal model which was used to calculate the PV module temperature based on measured meteorological parameters specific to the different regions of Turkey. The results of the thermal model are the stress factors that are then used in the electrical and reliability model to calculate the mean time between failures (MTBF) of various candidate module integrated inverters.

Rawdha Ameen presented a paper at the International Conference on Photovoltaic Science and Technologies (PVCon) in Ankara, TURKEY

Undergraduate student Ms. Rawdha Ameen presented a paper entitled “Flexible and Scalable Photovoltaic Curve Tracer” at the 2018 International Conference on Photovoltaic Science and Technologies (PVCon) in Ankara, TURKEY / July 4, 2018.

The reported the results of a project to develop a curve-tracer for use with experimental photovoltaic modules on curved-surfaces. MATLAB was used to control a Keithly SMU connected to multiple PV cells via a switching matrix. The system was able to sequentially take i-v curve measurements to cooroborate results obtained by sumulation on the reserach project.
