“…Several use cases are performed in the PC including LV network monitoring [3,7], state estimation [8], congestion management, fault management and SCADA reporting [4]. Communication to customer connection point is realized with BB-PLC over LV cables which provides enough communication capacity to monitor and control all connection points in real-time.…”

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.

“…The test results provided in [3,4,7,8] show that the LV network monitoring and state estimation for congestion management will enhance the LV network management. These features provide accurate and near real-time information of the LV network and it can be used to monitor the changes in the LV network accurately enough.…”

Traditionally, distribution network monitoring has been focused on primary substations (i.e., high voltage/medium voltage level), whereas low voltage (LV) network has not been monitored at all. With rapid growth and penetration of distributed energy resources in LV grids, there is growing interest in extending the real-time monitoring to LV level. The framework program FP7 European Project INTEGRIS proposes an integrated real-time LV network monitoring solution and implements it in a cost-efficient way. This solution integrates smart metering data with secondary substation measurements to get a more accurate and real-time view about LV grid, uses "decentralized" distribution management architecture to optimize data flow, and uses International Electrotechnical Commission 61850 Standardbased interfaces to improve interoperability. This paper focuses on information and communications technology perspective, explains the implementation details of this monitoring solution, and presents its functionality/performance testing results from two distribution system operator field trials and from real-time digital simulator laboratory.

“…Such example also hold for electric measurement devices. Driven by the concerns raised by distributed generation, some Distribution System Operators (DSOs) have already started the deployment of monitoring system to highlight Power Quality (PQ) issues for instance inverse power flow, voltage variations, and phase unbalances [7].…”

Traditional low voltage grids are equipped with meters for the accounting of the energy consumed by customers. Recently, the use of electronic meters offers the possibility of the remote reading. This paper deals with smart sensing: a secondgeneration Smart Meters replacing traditional metering device, and the first generation of electronic meters, in order to extract a richer and near real-time information. This information in then transferred on a fast communication network where is needed. In other words, the Smart Meters deployed over the distribution grid create a Sensor Network used for grid control and management. The intelligent unit employed in the proposed system is able to communicate using standard metering protocols like DLMS/COSEM, allowing high-level integration with systems that use this information for both billing and customer relationship management -as is today with Automatic Meter Management systems -and for the technical management of the LV power infrastructure like Distribution Management Systems. The paper presents a pilot installation in a real grid of the smart sensor network composed about 50 new-generation Smart Meters using fast -broad-band -communication. The network of Smart Metershas been used to monitor, during a measurement campaign of two months, the Power Quality of a part of the distribution grid. During the campaign, the grid voltage is below the 5 % of the nominal value only for the 3 % of the time, despite the large presence of distributed renewable resources.
