Best Practices for Integration of Utility Applications
The scope of this effort focuses on the evolution from an environment where a utility communications system was hard coupled to the supported application and the data source is coupled to the data consumer to one where all of these elements may evolve independently.
Two main topics currently being considered:
• Maximizing the use of existing and future communications infrastructure - This topic includes utility experiences in migration of legacy applications to newer communications technology, the factors influencing the choice between separate or converged communications infrastructure moving forward, and strategies which utilities have employed when opting for converging multiple applications onto a single communications system.
• Access to power system related data outside the traditional system boundary - This topic includes utility experiences related to the need for more and more applications to access power system related data including the challenges associated with data formats and accessibility. How utilities are dealing with cyber security aspects and strategies moving forward for a single data source (e.g. power system IED) to support multiple applications.
While there are many applications that are utilized within utilities today, this effort was focused on those which support the operation of the power system in one way or another such as: Power System Protection, Distribution Automation (DA), Substation Automation (SA), Demand Response (DR), Advanced Metering Infrastructure (AMI), Distribution Management System (DMS), Outage Management System (OMS), State Estimation, Automatic Generation Control (AGC), Supervisory Control and Data Acquisition (SCADA), Power Quality (PQ), Asset Monitoring, Wide Area Monitoring, Protection, and Control (WAMPAC), Distributed Energy Resources (DER), and Electric Vehicle (EV).
