Smart Grid Laboratory

The research team focuses on complex multidisciplinary research and development in the field of decentralized generation of electric power from renewable resources of energy, off-grid systems and their control. The team is membered with experts in power-engineering, metering and control techniques, informatics and mathematics.

The research team develops technologies for systems that support the cooperation and sharing of accumulation capacity among electric cars and stationary accumulation units to supply the grids (off-grids and mains).

The research team members provide a wide range of services in the field of diagnostics of electrical installations. The team specializes in the diagnostics of electrical machinery, both rotating and stationary, including the diagnostics of LT and HT electric grids.

The research team deals with the questions of electric network reliability. Available is a database of disturbing effects and power failures in the distribution networks. It is a functional software application accessible via a web interface and contains data since 2000. The research infrastructure, models and SW applications help to model and analyze network states with regard to reliability. This shall lead to more reliable supplies of electric power and better resistance of the network in non-standard situations.

Research Focus:

• Development of the system of monitoring, storing and evaluation of data to calculate the element reliability and general standards of electric power supply.
• Simulation and analytical methods to solve reliability schemes.
• Optimisation of reactive energy flows in the distribution networks.
• Effects of electric network parameters on ripple control reliability.
• Problems related to the connectivity of DES to the grid.

PD stands for partial discharge pattern which represents a studied phenomenon in part of our research. This post is to share the largest known available dataset online which is given by ENET Center for all purposes.
