This guide includes discussion on control, communications, and cybersecurity considerations when deploying smart distribution applications.
IEEE Draft Guide for Assessing, Measuring and Verifying Volt-Var Control Optimization on Distribution Systems
Electric utilities are seeking to improve the overall efficiency and performance of the distribution system while helping to achieve energy and demand savings and working to accommodate higher penetrations of distributed energy resources. Distribution Volt-var Optimization (VVO) can play a major role in accomplishing these objectives while maintaining safety, preserving assets, and meeting all operating constraints such as loading and voltage levels. Initial studies and experience show there is significant potential for energy savings, demand management and loss reduction through improved management of distribution voltage profiles and reactive power flow. Consistent methods are needed for verifying the benefits achieved by VVO systems that have already been implemented. Guidelines for modeling system loads as well as distributed resources and their response to voltage and var changes are needed along with methods for performing the evaluations to estimate total benefits. These benefits can then be evaluated as a function of the investment requirements for the improved VVO on a feeder by feeder or substation by substation basis and deployment priorities can be developed.
