A Standardized API for Distribution System Control and Management


Presented by: Poorva Sharma and Ron Melton

Advanced Distribution Management Systems (ADMS) are increasingly necessary to integrate operations across various systems and evaluate distribution applications in an efficient and timely manner. To accelerate the integration, evaluation, and deployment of advanced distribution technologies, it is beneficial to standardize the Application Programming Interface (API) for applications deployed in the ADMS environment. Standardized APIs provide a set of functions enabling developers to access the data and services by making logical references to the data model. These logical references remain the same irrespective of how the data or services are physically implemented.

This approach reduces the duration and high cost associated with application development and makes applications more portable and interoperable. In this presentation, we will show how with DOE sponsorship, researchers at PNNL, in partnership with other national labs and industry, used the Common Information Model (CIM) - a standard to describe the structural model of the electric power system - to develop the standardized data model and interfaces. We will also describe GridAPPS-D, an open-source, reference implementation of the standardized API developed to support this approach.
