Antitrust concerns in the modern public utility environment

Description: Direct regulation of public utility activity and behavior has been the predominant approach to protect the public interest in this country. Changes in technology, as well as new thinking about the optimum role of regulation, have created a changing atmosphere in all of the traditional public utility industries. Competitive markets for many of the products and services in these industries have been developing. While monopoly power will continue to exist in certain parts of these industries and r… more

Reducing the cost of energy delivery disruptions: The role of advanced technology

Description: In July and August 1996, the electric grid in the western Unite States experienced widespread power outages from southern California to western Canada. These large disruptions reminded us of the vulnerability of our energy delivery systems. While these disruptions may have been isolated events, there are a growing number of threats to the security, stability, reliability and safety of our national energy delivery systems. For a fraction of the billions of dollars a year these outages cost our e… more

The effect of the transmission grid on market power

Description: If competition could extend without hindrance through the entire extent of an electrically connected power grid, the US would have just two electricity markets, each with a uniform price. These markets would be competitive indeed. Unfortunately, losses and congestion present barriers to competition and thereby provide the likelihood of significantly increased market power. This paper begins the analysis of congestion as it affects the physical extent of markets and thereby affects the degree of… more

Multilevel converters for power system applications

Description: Multilevel converters are emerging as a new breed of power converter options for power system applications. These converters are most suitable for high voltage high power applications because they connect devices in series without the need for component matching. One of the major limitations of the multilevel converters is the voltage unbalance between different levels. To avoid voltage unbalance between different levels, several techniques have been proposed for different applications. Excludi… more

Interconnecting Single-Phase Generation to the Utility Distribution System

Description: One potentially large source of underutilized distributed generation (DG) capacity exists in single-phase standby backup gensets on farms served from single-phase feeder laterals. Utilizing the excess capacity would require interconnecting to the utility system. Connecting single-phase gensets to the utility system presents some interesting technical issues that have not been previously investigated. This paper addresses several of the interconnection issues associated with this form of DG incl… more

The future of GPS-based electric power system measurements, operation and control

Description: Much of modern society is powered by inexpensive and reliable electricity delivered by a complex and elaborate electric power network. Electrical utilities are currently using the Global Positioning System-NAVSTAR (GPS) timekeeping to improve the network`s reliability. Currently, GPS synchronizes the clocks on dynamic recorders and aids in post-mortem analysis of network disturbances. Two major projects have demonstrated the use of GPS-synchronized power system measurements. In 1992, the Electr… more

Analysis of the California WEPEX applications to FERC

Description: The major theme of this report is that the Western Power Exchange (WEPEX) Applications prevent the Independent System Operator (ISO) from clearing the market, and that this is the root of the most important problems. The proposed rules at fault (1) prevent the Power Exchange (PX) and other Scheduling Coordinators from passing on all of their bids to the ISO, and (2) prevent the ISO from dispatching beyond the point at which congestion is eliminated. Although it is generally accepted that these … more

ORCED: A model to simulate the operations and costs of bulk-power markets

Description: Dramatic changes in the structure and operation of US bulk-power markets require new analytical tools. The authors developed the Oak Ridge Competitive Electricity Dispatch (ORCED) model to analyze a variety of public-policy issues related to the many changes underway in the US electricity industry. Such issues include: policy and technology options to reduce carbon emissions from electricity production; the effects of electricity trading between high- and low-cost regions on consumers and produ… more

Simplifying generator siting and contract options

Description: This paper demonstrates the application of a clustering method designed to aggregate effects of individual generation shift factors,while preserving acceptable parallel path characteristics. It illustrates how several statisticalmetrics and modeling heuristics are used to determine criteria for clustering acceptance. Tradeoffs between cluster precision and effective cluster aggregation are illustrated using a 4-area system. These tradeoffs are shown to affect final cluster acceptability. The pa… more

Quantitative Assessment of Distributed Energy Resource Benefits

Description: Distributed energy resources (DER) offer many benefits, some of which are readily quantified. Other benefits, however, are less easily quantifiable because they may require site-specific information about the DER project or analysis of the electrical system to which the DER is connected. The purpose of this study is to provide analytical insight into several of the more difficult calculations, using the PJM power pool as an example. This power pool contains most of Pennsylvania, New Jersey, Mar… more

Energy Storage for Power Systems Applications: A Regional Assessment for the Northwest Power Pool (NWPP)

Description: Wind production, which has expanded rapidly in recent years, could be an important element in the future efficient management of the electric power system; however, wind energy generation is uncontrollable and intermittent in nature. Thus, while wind power represents a significant opportunity to the Bonneville Power Administration (BPA), integrating high levels of wind resources into the power system will bring great challenges to generation scheduling and in the provision of ancillary services… more
