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.
