LV grid automation, protection, monitoring and control: the gridspertise approach

Distribution System Operators (DSOs) worldwide face growing challenges in maintaining sustainable and reliable network management during the energy transition. The integration of distributed energy resources stresses ageing power systems, increasing contingencies and complicating fault management. While MV networks benefit from intelligent devices and automation to accelerate fault location, isolation, and service restoration, LV networks typically rely on time-consuming manual interventions. This paper describes the solution developed by Gridspertise to improve LV network operations. The solution comprises an LV SCADA system which provides DSOs with remote monitoring and control capabilities. Leveraging on industry-standard protocols, the developed SCADA can integrate seamlessly into existing DSO infrastructures. At this regard, it can be interfaced with Remote Terminal Units (RTUs) that are housed in street cabinets and run automation logics designed by Gridspertise to enhance system restoration after power outages. Test results demonstrate the effectiveness of the automation logic in minimizing power outages following overload and short-circuit conditions.
