| 07-01 | Reliability Assessment Incorporating Operational Considerations and Economic Aspects for Large Interconnected Grids
The increasing frequency of transmission congestion due to the more intensive use of the grid, brought about by the entry of many new players and by the proliferation in the number of transactions, has created a critical need for the assessment of the reliability of the bulk system. This project's aim was to construct models with appropriate level of detail of the operational procedures and economic aspects, and use them to develop effective tools for evaluating the reliability and the associated economics of large bulk systems such as those of the RTOs/ISOs currently in formation.
The project research team has successfully met this aim and brought about advances in the modeling and the development of tools for reliability evaluation. Furthermore, the project has established a solid basis for linking economics, reliability and security.Final report for PSERC project "Reliability Assessment Incorporating Operational Considerations and Economic Aspects for Large Interconnected Grids"(M-8).

| 07-02 | Modeling Market Signals for Transmission Adequacy Issues: Valuation of Transmission Facilities and Load Participation Contracts in Restructured Electric Power Systems
Market-driven merchant transmission investments are contemplated as viable alternatives to regulatory-planning based investments. Two components are essential for inducing new transmission investments through market forces. First, price signals are needed to signify efficient investments, specifically, to help with the decisions on where and how much to invest. Second, proper (ownership and service) rights need to be introduced and awarded to investors as returns for recovering their capital and operating costs and creating the financial incentives. This project tackles several issues central to the two components: modeling market signals for inducing transmission-adequacy-driven investments and investigating market-based mechanisms for compensating such investments. Research findings are summarized in three areas.

| 07-08 | Condition Indicator Analysis for the Enhancement of Power System State Estimators
Most utilities have state estimators in the package of energy management systems. The main functions of state estimators are to represent steady state system voltage, currents, and power flows – utilizing mathematics to enhance the accuracy of measurements. In this report, the author examines how the new technology of phasor measurement units (PMUs) can be used to enhance state estimation in electric power systems. A study and review of condition analysis for state estimation is presented in this report. The study reveals that decreasing the condition number of the gain matrix increases the accuracy of state estimates.

| 07-16 | The Electric Power Industry and Climate Change: Power Systems Research Possibilities
In response to increasing concerns over global climate change, this white paper identifies possible research needs for PSERC to pursue that are related to interactions between the power industry and global climate change. The technologies that can aide in the mitigation and adaptation to climate change trends have to be enabled by the power system infrastructure. Contributions could come through researching and clarifying the following: (i) power infrastructure capability to respond to climate change and extreme weather events; (ii) relative impact of climate change issues on system operating strategies (e.g., system dispatch), system configurations (e.g., microgrids), and expansion plans; (iii) system effects of an expanded use of renewable and alternative energy technologies; and (iv) impacts of market rules and policy mandates on the operations of the power system and, subsequently, on the national economy.

| 07-17 | Uncertain Power Flows and Transmission Planning
Growing uncertainty in power systems, coupled with the introduction of power markets, calls for the development of new tools for planning, operations, and market-based decision-making. This project explored methods for efficiently calculating available transfer capability and quantifying transmission revenues under uncertainty. Illustrative analyses demonstrated potential uses in transmission planning.

| 07-31 | Reliability Based Vegetation Management Through Intelligent System Monitoring
Most vegetation management programs for distribution systems are calendar-based. The level and efficiency of distribution system reliability could be enhanced if feeders were trimmed only when necessary. This project was a first attempt to monitor and record power system data in the hope of developing tools to assist utilities in developing customized tree-trimming schedules to achieve desired levels of reliability, based on the level of vegetation contact activity and weather parameters. Conceptually, by monitoring system parameters and vegetation-related outage occurrences, utilities could tailor their tree trimming cycles for each feeder, resulting in a predictable level of reliability for a given circuit.

| 07-38 | Automated Circuit Breaker Monitoring
A complete system for automated monitoring of multiple circuit breakers is developed for DOE by Texas A&M University. This system is characterized by a wireless-based architecture for data communication between newly developed Circuit Breaker Monitors (CBMs), as well as concentrator computer with intelligent software for automated analysis.
