Advanced Distribution Management System (ADMS) from Oracle

An ADMS is a software platform that helps electric utilities monitor, manage, control, and optimize the distribution grid and restore service after interruptions. It brings together operational capabilities such as outage management, supervisory control and data acquisition (SCADA), and distribution management to give operators a coordinated view of grid conditions and operations.

An ADMS can provide utilities with coordinated capabilities for operating the distribution grid, including real-time monitoring and control, outage management, fault analysis, network switching and service restoration, power flow analysis and state estimation, voltage and reactive power optimization, forecasting, distribution optimization, and distributed energy resource management. These capabilities help operators understand changing grid conditions, coordinate decisions, and take action across the distribution network.

An ADMS supports broader distribution grid operations, including outage management, distribution analysis, optimization, network switching, and service restoration. SCADA focuses on real-time monitoring and control, giving operators information about network conditions, equipment status, alarms, and events and providing controls for grid devices. SCADA capabilities can operate as part of a broader ADMS environment.

An ADMS supports the broader operation of the distribution grid through capabilities such as real-time monitoring and control, distribution analysis, optimization, network switching, and service restoration. An OMS focuses on detecting, assessing, and managing service interruptions and coordinating service restoration. OMS capabilities help utilities understand outage conditions, customer impacts, service restoration activities, and operational priorities. An OMS can operate as part of a broader ADMS environment.

An ADMS supports the broader operation of the distribution grid through outage management, real-time monitoring and control, distribution analysis, optimization, and service restoration. A distributed energy resource management system (DERMS) focuses on monitoring, coordinating, and managing distributed energy resources such as solar generation, battery storage, electric vehicles, smart thermostats, and flexible loads. DERMS capabilities can extend ADMS functions so utilities can coordinate distributed resources with broader grid operations.

FLISR stands for fault location, isolation, and service restoration. It helps utilities identify the likely location of a fault, isolate the affected section of the distribution network, and restore service to customers outside the faulted section where possible. FLISR can help restore service faster and improve network reliability. The level of automation depends on the utility’s network, operational processes, data quality, and deployment approach.

FLA helps utilities estimate where a fault has occurred on the distribution network. It uses network and operational information to help operators narrow down the possible fault locations, make better crew dispatch decisions, and reduce the time required to investigate faults and restore service.

An ADMS can help improve distribution grid reliability by combining real-time visibility into network conditions with fault analysis, network switching, service restoration, distribution automation, and optimization. These capabilities help operators identify problems, isolate affected areas, restore service where possible, and adjust grid operations as network conditions change.

An ADMS can help utilities manage a more distributed and dynamic grid by combining real-time visibility into network conditions with distribution analysis, optimization, outage management, device control, forecasting, and distributed energy resource management capabilities. Together, these capabilities help operators understand changing network conditions and coordinate operational actions across the distribution network.

An ADMS can support grid modernization by bringing together operational capabilities that utilities can expand as grid and technology requirements evolve. Utilities can adopt capabilities such as outage management, SCADA, distribution management, optimization, and distributed energy resource management as their operational priorities and grid requirements change.
