Distribution Automation and the Future of DER at Electric Cooperatives
- Jim Weikert, Lead Utility Automation Consultant, Power System Engineering, Inc.
- Ken Cooper, Senior Utility Automation Consultant, Power System Engineering, Inc.
This course reviews the expansion of DER that is occurring and its impact on managing feeders. The discussion will cover utilities California with significant DER growth as well as highlight how utilities outside of California can prepare themselves. It will talk as well about practical aspects of implementing distribution automation (DA) programs for improving reliability and saving money through automated switching, demand based voltage reduction and other programs. The course will cover the following:
- Distributed Energy Resources: The industry is changing rapidly in developing standards for monitoring and controlling DER. The course will discuss a California municipality which is working to address high penetration of DER due to Zero Net Energy requirements as well as cooperatives across the country facing much lower PV penetration. It will cover the challenges that DER creates for traditional DA programs and provide recommendations of steps to take now in preparation for DER. It will also talk about emerging standards and adoption of them by the industry.
- ADMS/DERMS Systems: SCADA vendors are expanding their systems beyond DA to be able to manage DER more effectively. The course will review where many vendors are at so that attendees can consider how to select systems which are being designed for future DER needs.
- Restoration: We will discuss the practical steps of automating fault detection, isolation and restoration (FDIR). We will start with practical steps being used to bring fault data back and locate faults better using AMI, SCADA and OMS. We will cover practical considerations around safety, communications and load monitoring for FDIR as well.
- Volt/VAR Optimization: The course will also discuss examples from utilities implementing VVO. It will cover the important considerations of Conservation Voltage Reduction (CVR) including evaluating feeder voltage profiles and integrating DA with AMI to use end-of-line voltage for real time control.
- AMI Support for DA & DER: The course will discuss common AMI uses such as measuring line voltage for DA as well as approaches to more challenging problems such as measuring real time load with significant DER penetration. The course will provide examples of a utility using AMI to communicate to DA devices.
- Communications for DA & DER: Finally the course will cover the critical impact that communications has on the effectiveness of DA and discuss how to design your communication system to support effective DA programs.
