Active distribution network concept for distributed management of low voltage network

Abstract

The paper proposes a concept and architecture for distributed low voltage network management. Active distribution network concept is capable of real-time monitoring of whole grid and it may utilize the flexibility of distributed energy resources to enhance the hosting capacity of low voltage networks. The proposed architecture creates a bridge between fully centralized automation systems like SCADA and distributed system consisting of secondary substation automation and smart metering. In this way the proposed system extends the existing automation system to low voltage networks. It may also provide required real-time visibility and operational management to low voltage network without overloading the centralized automation system. The system has been designed for multiple low voltage network use cases like network monitoring, congestion management and fault management.
