Local Balancing of Low-Voltage Networks by Utilizing Distributed Flexibilities as Part of the InterFlex Field Trial

The growing share of Distributed Generators (DG)
brings with it a fundamental change in dispatchability and location
of the overall power generation portfolio. A significant share
of DGs are renewable-based and connected to the distribution
system, replacing the conventional generators placed at high voltage
levels. With this fundamental shift in the power system, more
active approaches to distribution system operation are required.
In this paper the authors propose a model to utilize distributed
flexibilities to locally balance power generation and demand,
minimizing the power exchange between low and medium voltage
levels. The proposed model is applied to several low voltage
networks in the German distribution system. Simulation results
show that the proposed model decreases the peak load in tested
LV networks by 2.6-12.5%, and leads to an overall flattening of
the load profile.
