3 PhD positions in the Smart Cities EMC research projectThe EMC

(Electromagnetic Compatibility) group is part of the Institute of Electrical Engineering, Faculty of Computer, Electrical and Control Engineering at the University of Zielona Góra.

JOB DESCRIPTION

Position 1. Behavioural modelling and simulation of active components, focus on energy suppliers (PV, inverters), so T-F, V-I 

Objectives: Study of the two-port network behavioural modelling of the power converters for renewable energy sources that feature non-linear static behaviour. Develop a procedure for the terminal identification, so-called black-box modelling approach when engineers do not have an access to the internal structure, control and dynamics of the converters, but through appropriate measurements can extract needed information useful later for the system level simulations and stability analysis. In this case commonly used Smart Grid system elements (renewable energy sources, power electronics) are treated as interference sources. Average models for system-level verification shall also be developed. 

Expected Results: Black-box modelling procedure. Validated models for Smart Grid elements. Implementation in design tools. Automated behavioral model maker. 

Position 2. Statistical modelling of non-linear devices, and impact of spread and large numbers

Objectives: Development of a general framework, where a generic nonlinear circuit, device or appliance with an arbitrary number of terminals can be included as a black-box component, no matter its internal description. Extension of the state-of-the-art concerning the statistical simulation of circuits affected by random electrical parameters (changes of HF parameters of the circuits, converter modulation effects, aggregation of interference generated by multiple sources, etc.) by means of the polynomial chaos framework. Maintain full compatibility with commercial circuit simulators (i.e., SPICE-type) or freely available (R-project, etc.) and validate through the statistical analysis of a realistic energy conversion system for smart grids. Show by comparison against Monte Carlo simulations the advantages in terms of accuracy and simulation time. 

Expected Results: Validated parameterized models and design methodology as stand alone. Validated parameterized models and design methodology embedded in the system topology in WP8. Toolbox and techniques for statistical analysis and optimization of system equipment.

Position 3. Probabilistic large-system EMI (interaction) analysis using EM topology, and embedding the validated models

Objectives: Development of advanced tools and techniques for power system performance analysis. Particular reference to stochastic methods will be given to analyze the effect of variation. Incorporating risk in analysis through probabilistic tools and assessment in light of the increasing complexity of smart networks. Advanced numerical methods with particular reference to interference evaluation in 

power systems. Detailed analysis of the Smart Grid power line data transmission reliability in a presence of electromagnetic interference. 

Expected Results: Validated set of tools and expert systems using statistical techniques of complex systems for PQ and EMC and determination of risk on interference, implementing WP6 results. Analysis of effect of interference to power line communication following statistical approach.

PROJECT DESCRIPTION

The vacancy is part of the SCENT project in Marie Skłodowska-Curie Innovative Training Networks (ITN), European Joint Doctorate, funded by the H2020-MSCA-ITN-2018-812391 grant. The SCENT consortium is comprised, in addition to the University of Twente (NL), by the University of Zielona Gora (PL) and The University of Nottingham (UK). Successful candidates will receive a joint doctorate from these three universities. The project is supported by the IEEE EMC Society TC7, Dutch EMC-ESD association and 12 industries


SUMMARY OF THE PROJECT

The global vision of Smart and Sustainable Cities is greatly restricted by the rapid increase of interference and interoperability problems which occur through the interaction of electrical power with information technology and communications equipment. This interconnected systems-of-systems infrastructure creates a complex electromagnetic environment in which interoperability of the electronic systems has to be achieved. There is an urgent need to conduct greater understanding in Power Quality (PQ) and (conducted) Electromagnetic Compatibility (EMC) due to the changing dynamics of the field. The main issue is the insufficient number of qualified engineers for the latest developments in smart cities, renewable generation and electric vehicles. A highly trained cadre of engineers (a new breed) is required to lead this area. To date no specific doctoral programme in this field is available in Europe resulting in well trained researchers and engineers being scarce. SCENT will create a network to train highly skilled engineers through an integrated doctoral training program based on the essential research required in PQ and EMC that can underpin all future technological developments, strongly linked to industry, and bridging the gap between research and industry for translation of new knowledge. Designed into the project are specific innovations with methodologies to optimize the design of power distribution networks inside buildings and industrial plants, as well as transport systems, with respect to compatibility (no interference) and efficiency in the distribution networks and connected electronic systems. The partners of the network consist of leaders in these fields and relevant industrial stakeholders resulting in a unique and effective network in Europe and globally. Dissemination methods to realize optimal impact will include scientific publications, workshops, training of engineers in industry, and dissemination through newsletters, interviews, social media.
