Low Voltage network modelling gives visibility into secondary power mesh

The Oracle Utilities Network Management System provides distribution network operators with increased visibility and management of low voltage, secondary mesh, underground networks. 

While utility distribution operators have had visibility into their high and medium voltage networks, they haven’t had the same level of near real-time operational visibility into the underground low voltage, and secondary mesh networks used in many cities. These are historically highly reliable and have inherent redundancy, and so don’t have a high priority. However there are increasing failures in these networks as the equipment ages and intermittent distributed renewable resources are added at the edge of the grid.

Many European and Asian utilities carry electricity to customers via extensive low voltage networks that typically don’t have the visibility and accountability of HV or MV networks. One major North American city, for example, has a vast underground distribution network that carries 86 percent of the total load via low voltage, secondary lines. In a dynamic network, visibility of these networks is becoming a requirement alongside reliability and redundancy.

“As we continue to see more disruptions and failures in underground low voltage secondary networks in cities around the globe, the need for near real-time visibility into network performance is becoming more critical. Oracle Utilities is in a unique position to provide such detailed low voltage network management visibility which will enable utilities to provide a safe, secure and reliable power supply for years to come and to increase flexibility to support growth in their cities,” said John Villali, Research Director for IDC Energy Insights.

The new Low Voltage Network Management capability in the Oracle Utilities Network Management System provides modeling, analysis and ongoing management and optimization of complex mesh and low voltage networks, helping operators monitor faults and resolve them in an automated fashion. By better modeling and managing these networks, utilities can manage the low voltage edge of the grid as part of their core operations, enabling them to: reduce recurring crew visits for fault and outage resolution; better forecast load and plan accordingly; help identify which assets are approaching the end of their lifecycle and need to be replaced; and improve overall system reliability and customer satisfaction.

“Underground low voltage network assets continue to age, and their reliability and resiliency has been further challenged by the inherent intermittency of distributed energy resources. As utilities strive to place a strong emphasis on customer-centricity, these new challenges are creating a dire need for more visibility, control and proactive maintenance and optimization of low voltage networks. Oracle Utilities Low Voltage Network Management capability is unique in its ability to respond to these needs, agnostically, either within our Oracle Utilities Network Management  Solution or alongside others’ distribution management products,” said Rodger Smith, general manager and senior vice president at Oracle Utilities.
