Tutorial 4
Role of the Distribution Management System in Modern Distribution
Systems
Background
The requirements for managing distribution systems continue to present new
challenges. Distribution system voltage and var control is now being called on to help
improve the energy efficiency of customer loads. Reliability improvement is still a top
priority and additional requirements to improve performance during major storms and
cyber security incursions must also be considered. All of these requirements are
combined with the need to integrate distributed generation (such as PV), distributed
storage, and demand response. The result is a need for a true model-based
management system with improved methods of model management, integration of
measurement data from sensors and from advanced metering systems, advanced
models for customers, and new simulation approaches both for real time operations and
for planning of the distribution system.
Aim of the tutorial
The tutorial brings together experts from both Europe and North America to examine the
latest developments in distribution management systems and the requirements for
distribution management systems of the future. The tutorial will illustrate important DMS
applications and describe new approaches for dealing with these applications. These
applications include advanced voltage and reactive power control, integration of
distributed resources, demand response, real time state estimation for optimizing
performance, automatic reconfiguration, integration of advanced metering, etc. The
tutorial will include a focus on modeling requirements for the distribution system of the
future to support real time simulations, voltage control, new load models, and integration
of distributed resources.
