White Paper - The Advanced Distribution Management System (ADMS) - Managing the distribution network in the Smart Grid era

Version 1

    The Advanced Distribution Management System – ADMS – brings together distribution management system (DMS), supervisory control and data acquisition (SCADA) and outage management system (OMS) technologies , along with control room applications, on one, secure platform with a single user interface. With this comprehensive mission critical solution, the electric utility can monitor, analyze and control the distribution network to improve the level and quality of service.


    At its core is the network model representing the as-operated state and based on the as-built state defined by the geographic information system (GIS). A load flow algorithm responds quickly to data sourced from throughout the network to analyze the balanced, unbalanced and dynamically changing network in real time. Users across the network – operators, dispatchers, management, planning engineers and others – have consistent visualization of model results in geographic, schematic and single-line diagram views. State estimation validates viewed data and estimates non-telemetered points to achieve a complete network representation.


    With this accurate network model and a portfolio of robust functionalities, the utility is empowered with continuous, real-time analysis of the operational state of the network that enables self-healing capabilities. Demand can be managed through reduction of technical losses; by forecasting near-term load and applying volt/VAR control for peak shaving; and by securely integrating and managing distributed energy resources, including energy storage, to flatten the daily load curve. These and other options enabled by ADMS are key to managing demand in the face of increasing energy usage, surging energy costs and network infrastructure instability due to aging.


    The ADMS represents the evolution of control room technology that will help utilities mobilize to meet increasing consumer demand and environmental obligations and reap many of the benefits all stakeholders expect from their smart grid investments.
