The main fields of interest are systems engineering and grid planning questions related with low-voltage direct-current (LVDC) power distribution systems. The main objectives of the research are the formulation of the related optimisation problems, the definition of the applicable solution methods and principles, and the analysis of the role of the LVDC systems in the future power systems. Central themes are techno-economic optimisation, analysis of feasible use cases and applications, electrical safety questions, control architectures and development of standardisation. The special emphasis is on the LVDC systems for utility networks and versatile microgrid solutions, however, the main goal is to develop generic planning methodologies suitable for all applications and both system engineering and network planning. In addition, microgrids related business models for electricity markets are addressed. The adoption of LVDC systems is supported by the favourable price development of power electronics, the significant increase in the transmission capacity of the low-voltage grids, and the improved grid service quality for the end-customers. The smart functionalities of the embedded converters provide means to meet the stringent demands imposed on the cost efficiency and service quality of electricity distribution. The LVDC distribution provides new opportunities for grid management and electricity trade.
