The ongoing integration of high-power devices such as heat pumps, photovoltaic systems, home storage, and electric vehicles is putting a strain on European low-voltage grids. While the speed of uptake of these new devices often cannot be matched by the increase in grid capacity, DSOs can leverage the high amount of operational flexibility they offer as an alternative to grid reinforcement. However, this calls for the incorporation of novel Active Distribution Network Management (ADNM) concepts that overcome the reduced availability of power flow and voltage control options and near real-time measurement data in low voltage grids.
This paper elaborates on the findings of a survey and sharing session organised by the Technology and Knowledge Sharing Committee of E.DSO on the topic of ADNM in low-voltage grids and presents three case studies on the topics of short-term load forecasting, distribution system state estimation, and home energy management systems. Based on these insights, several recommendations are presented with a focus on innovative concepts for ADNM, regulatory aspects and the role of DSOs.
