Advanced Distribution Management Systems: Connectivity Through Standardized Interoperability Protocols

Abstract

The electric power system is evolving from a centralized generation model toward a complex distributed infrastructure with potentially millions of controllable generators and load prosumers. Transformative changes are especially pronounced at the distribution system level, with applications of new technologies influencing policies, planning, and utility operations. Consumers of electric power are also evolving, as they now generate electricity locally and utilize the Internet of Things for managing their home electric use and interfacing with grid applications. Evidence of this abounds, from the high penetration of rooftop solar installations and other distributed energy resources (DERs) that are transforming electricity consumers into prosumers (who consume and produce electricity) to the proliferation of controllable smart appliances reacting to signals and changing the pattern of power consumption. Key attributes common to the evolution of the distribution system and consumers include the significantly increasing level of data connectivity, interoperability, and systems integration required for realizing the benefits of adopting new technologies at scale.
