Integration of Customer Systems into Electric Utility Infrastructure (EPIC Project 2P5) |
San Diego Gas & Electric Company |
The primary objective of EPIC-2, Project 5 was to investigate and address the evolving gateway between
customers and utilities to facilitate increase in reliable deployment of clean energy technologies to support distribution systems.
More specifically, the project focus was on performing pre-commercial demonstration of advanced
monitoring schemes, root-cause analysis tools, and assessment methodologies for safe and reliable integration and interoperability of customer systems with the distribution system to improve power system operations and thereby increase ratepayer satisfaction and benefits. |

Low Voltage Network Protection Utility Workshop - Summary and Next Steps |
Sandia Report: Zheyuan Cheng, Eric A. Udren, Juergen Holbach, David Hart |
Increased penetration of Distributed Energy Resources and microgrids have fundamentally changed the operational characteristics of Low Voltage (LV) network systems. Current LV network protection philosophy and practice are due for a significant revamp to keep up with changing operating conditions. This workshop invites four of the major LV network users in the US to discuss the challenges they face today and the new technologies they have been experimenting with. In light of this workshop discussion, use cases for further hardware-in-the-loop testing efforts are proposed to evaluate new LV network protection solutions. |

Roadmap for Advancement of Low-Voltage Secondary Distribution Network Protection |
Sandia Report: Eric A. Udren, David Hart |
Downtown low-voltage (LV) distribution networks are generally protected with network protectors that detect faults by restricting reverse power flow out of the network. This creates protection challenges for protecting the system as new smart grid technologies and distributed generation are installed. This report summarizes well-established methods for the control and protection of LV secondary network systems and spot networks, including operating features of network relays. Some current challenges and findings are presented from interviews with three utilities, PHI PEPCO, Oncor Energy Delivery, and Consolidated Edison Company of New York. Opportunities for technical exploration are presented with an assessment of the importance or value and the difficulty or cost. Finally, this leads to some recommendations for research to improve protection in secondary networks. |
