SMUD Theoretical Reliability Improvement: Line Automation & Automatic Sectionalizing and Restoration (ASR) Projects
December 2013
As part of the SmartSacramento® project, partially funded by the Department of Energy (DOE) Smart Grid Investment Grant (SGIG), SMUD committed to implementing Advanced Operating System (AOS) control strategies in an effort to improve distribution efficiency and system reliability. The control strategy for improving system reliability is Automatic Sectionalizing and Restoration (ASR). SMUD, in conjunction with The Structure Group, developed new control logic to implement ASR via SMUD's existing Siemens SCADA system. The ASR control logic utilizes the equipment installed as part of the substation SCADA retrofit and line automation projects. The line automation project has several components. One aspect includes the installation of 12kV overhead line reclosers and pad-mounted switchgear with motor-operated switches. Both types of line devices are remotely controlled and have automatic functionality. The installation of these line devices is expected to improve service reliability by automatically sectionalizing a feeder when a permanent fault occurs on the feeder mainline and on the load-side of the devices. Additionally, the installation of these line devices enables the implementation of the ASR project. The ASR project consists of development and implementation of ASR control logic to provide faster service restoration than what can be achieved through manual switching alone. The objective of installing the remotely-controlled, automatic line devices and implementing the ASR control logic is to improve distribution reliability by reducing customer minutes of interruption (CMI) and, therefore, SAIDI1 for customers served from the project feeders.

Honeywell International, Inc. (Full-Scale Implementation of Automated Demand Response)
November 2013
Honeywell is demonstrating, on a utility program scale, commercial acceptance of automated demand response (autoDR) working with Southern California Edison (SCE), Pacific Gas and Electric Company (PG&E;), and San Diego Gas and Electric (SDG&E;). Honeywell is providing a turnkey utility-style program effort to sign up and implement technology for commercial and industrial customers whose average electric load exceeds 200 kW. Large-scale customer adoption of autoDR enables SCE and PG&E; to initiate and automatically execute customized load shedding and other strategies in response to peak load event notifications or price signals. Honeywell provides all aspects of customer delivery for the autoDR program, including customer audits, installation of customer-sited automated load control devices, and recommendations for optimal demand response strategies. This project coincides with the California utilities adoption of critical peak pricing (CPP). CPP is a mandatory tariff for new, large commercial customers that will push electric rates approximately 10 times higher during high electric demand days, but offers customers a lower daily rate for non-critical peak days.

A smart meter is usually a digital electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily, but frequently hourly or even at 15-minute intervals, back to the utility for monitoring and billing purposes.
Washington-St. Tammany Case Study - Stress-Testing Designs Before Deployment - INTERIM REPORT
November 2013
All Smart Grid installations require design review prior to installation. However, several factors make early and rigorous review of communications designs especially critical: * Communications is an enabling technology for all other Smart Grid functions and devices. * Radio, wireless, and cellular communications are subject to environmental conditions that vary with geography. * Radio, wireless, and cellular communications are subject to environmental conditions that vary over time. (Examples of this include weather, solar activity, and interference from industrial operations.) It helps to have many sets of eyes on a communication design, and utilities must be open to feedback at each step. Sometimes they must make the difficult decision to change designs after implementation has begun. This was demonstrated when Washington-St. Tammany Electric Cooperative ran into a particularly difficult and surprising problem when deploying a communications system intended to connect transmission breakers to its supervisory control and data acquisition (SCADA) system. The problem was unique to the area Washington-St. Tammany serves. However, the need to thoroughly stress-test communication designs is universal. This case study is meant to illustrate that need and highlight the success of that co-ops deployment in the face of unexpected developments.

NYPA Evaluation of Instrumentation and Dynamic Thermal Ratings for Overhead Lines - Final Report
October 2013
The demand for electric power over transmission circuits is increasing at a faster rate than the construction of new transmission facilities. This trend is pushing the capacity of many transmission circuits beyond operation margins required for contingencies. The power capacity (i.e., the rating) of most overhead transmission lines is prescribed by the so-called static rating based on both the conductor configurations and the environmental conditions. Ideally, very conservative worst-case assumptions about environmental conditions are used when developing these static ratings. Due to this conservative approach, significant extra power capacity exists beyond the design margin on most lines most of the time.
