Electric Power Systems Lab

The work of the Electric Power Systems Lab addresses grid operation in connection with decentralization and restructuring in the energy generation sector. The focus at the transmission and distribution grid level is on the simulator-supported investigation of grid operation issues relating to system management and grid reconstruction. An operationally realistic network training simulator (PowerSystemSimulator PSS) is being further developed and used for the investigations. For research at the low-voltage level, an existing MicroGrid in the 50...200 kW power class will be upgraded and developed into a SmartGrid real laboratory. Within this research laboratory, a real system infrastructure will be available that allows combining the electricity, heating, cooling and mobility sectors in order to investigate technologies and their cross-sector interconnection in real operation.

The Electric Power Systems Laboratory investigates the design and insulation of high-voltage switchgear, as increasing inverter-fed power generation changes the insulation requirements of the equipment. Regarding plant-oriented laboratories, such as the high-voltage hall and the climatic chamber, extensions or replacement constructions are planned in order to scientifically investigate the behavior of future high-voltage equipment with new types of environmentally friendly insulating materials (instead of SF6 and mineral oils) under climatic and pollution conditions. A broad area of basic research will be facilitated.
