Mulualem T. Yeshalem Currently, I am studying my PhD at the University of Nottingham on a joint European Research project SCENT ‘’Smart Cities EMC Network for Training’’ funded by the Marie Skłodowska-Curie Actions. Which is a consortium of three Universities the University of Nottingham (UK), University of Zielona Gora (Poland) and University of Twente (Netherland). I’m employed at the Graduate School of University of Nottingham (UK) (Joint Degree with UT and UZ)
I have Bachelor of Science degree in Electrical Engineering from Hawassa University in 2011, I graduated in Master of Science (MSc.) degree in Energy Engineering and Power system from the Institute of technology of Hawassa University in 2016.
I have a five-teaching experience in two universities, Adama Science and Technology University (ASTU) and of Hawassa University. As part of my research, I published one article on AIMS Energy journal entitled, “Design of an off-grid hybrid PV/wind power system for remote mobile base station: A case study”. And Intechopen book publisher “Microgrid Integration, a Special Topics in Renewable Energy Systems”
My Project (ESR4) Behavioural modelling and simulation (T-F, V-I) of active components, focus on energy consumers, and interaction with power line communication
My task is developing a procedure for the terminal identification i.e. black-box modelling, as for ESR1. In this task interconnect and black-box models will be developed using vector fit of the frequency dependence and macro models of the non-linear properties for input/output of active circuits and embed them in power system models, focusing on appropriate models for frequencies above 2 kHz where data is scarce but interference with power line communication is more problematical. In this case, the common terminal equipment, i.e. power consumers will be analyzed. The focus will be on the 2 kHz – 150 kHz range, with one decade below and above.
Work package 5: Behavioural modelling and simulation (T-F, V-I)
Modern electronic systems draw current during a very short period of time, causing transients (microsecond timescales), sags and surges (milliseconds) and harmonic distortion in the power distribution system. In this WP non-linear models (parametric macro-models) to be used in the time domain (so not only line-commutated), is investigated, developed and applied. With this approach, the non-linear and dynamic effects of electronic devices will be taken into account. Such device models will then be integrated into a typical "topological" approach for the simulation of a whole system, which will be carried out in WP8, resulting in models for components and devices to be used within the power distribution design environment.
