Distributed Energy Systems

Renewable Energy production is spread over the territory and cannot be controlled in time in the same manner as traditional centralized energy production. Small to medium scale renewable energy plants are connected to the grid with Active In-feed static Converters (AIC) with low inertia. Some consumers install PV plants on their roofs, becoming energy producers at some time of the day. Moreover, the trends to electrification of mobility and house heating bring new controllable consumers loads.

Thus, long time established protection schemes in case of earth fault or overload are not efficient anymore. Voltage levels at the consumers connecting point can variate much more than in the past and in both directions in function of the power balance.

These new paradigms force us to rethink many aspects of electrical energy distribution. Our role at NERC is to understand, develop or evaluate new solutions for the distributed energy production and storage in consideration of energy efficiency, sustainability and costs for implementation. Beside traditional electrical engineering equipment, the DES Laboratory is equipped with state-of-the-art research tools including advanced simulation software, Hardware in the Loop (HIL) real time target and grid simulator. The new grid control solutions, protections, in-feed and battery converters or ICT element can be tested in realistic environment.  Our expertise and the DES infrastructure are offered for applied research, teaching or consulting activities.
