| 06-10 | Executive Forum on Solutions to Transmission Investment
PSERC Executive Forum, April 21, 2006, in Chicago, IL. This Forum provided an opportunity for senior managers and PSERC experts to identify critical challenges and possible solutions to (1) transmission investment and pricing issues, and (2) issues related to enhancing grid reliability. The report summarizes participant ideas on the challenges to be overcome and the solutions for doing so. | | 11/15/2006 | 168.9k | PDF |

| 08-14 | Reliability, Electric Power, and Public vs. Private Goods: A New Look at the Role of Markets
A public good is a shared commodity, like a street sign, such that use by one person does not reduce the enjoyment of another person. Unlike private goods, use is not exclusive which leads to free-riding, where a benefactor of a service does not pay for it, and under-provision. To explore the issue of public goods in the context of an electric energy supply and delivery system, this work:
lays out an appropriate conceptual framework for analyzing power markets using an economic/engineering model of optimal investment and operation,
provides simulations and experiments that show both an ideal system and the potential for market power in real time markets,
draws research conclusions, and
makes specific recommendations for market structure and operation that properly take into account the need for reliability.

| 08-15 | Massively Deployed Sensors
This is a final project report for research on the subject of massive deployment of sensors in electric power systems. There are several areas where the addition of modern, economical sensor technology can improve the quality of a large electric power grid. This report provides a quick reference for a variety of applications of massively deployed sen-sors (along with the advancement of communication and computer technology) that are currently being used and are also in the research and development stage. The report spans a wide spectrum of instrumentation technologies, largely correlated to the several forms of energy, namely electric, magnetic, atomic, chemical, kinetic, and potential.

| 08-16 | Evaluation of Alternative Market Structure and Compensation Schemes for Incenting Transmission Reliability and Adequacy Related Investments
Incentives for attracting investments in transmission assets are essential to the overall success of the restructuring of the electric power industry. In general, adequate transmission capacity enhances reliability, lowers energy cost as delivered, limits market power of market participants, and provides flexibility to protect against market uncertainties such as load fluctuation, fuel price volatility, and unexpected facility outages. Various transmission-pricing approaches have been developed for recovering transmission costs and providing incentives for future expansion or enforcement. According to the market-based investment model, a transmission investment usually expands power-transfer capability, and therefore, increases the quantity and variety of transmission rights can be issued to investors. This project tackles problems related to the evaluation of market-based schemes for compensating transmission investments.

| 08-17 | Agent Modeling for Integrated Power Systems
Countries around the world continue to refine their electricity market structures in various ways. There are ongoing debates over market design issues, such as how to design effective market power mitigation rules, how to incorporate ancillary service markets, and how to properly implement a retail electricity market to encourage customer participation. Although valuable experience has been gained, there is a lack of a robust analysis platform for evaluating the effects of a new market design from both engineering and economic points of view.
The difficulty in creating such a platform arises from the interactions among strategic behaviors of market players, various layers of market designs, and the underlying physical network. A multi-agent system with a corresponding software platform would allow for robust analysis of the complex phenomena of an electricity market with its human decision-making in the context of market rules and a physical electric system.
In this research, multi-agent electricity market simulation tools were designed and implemented. Three market design areas were investigated: market power mitigation, ancillary service market design, and customer participation.

| 08-18 | Detection, Prevention and Mitigation of Cascading Events
When a power system is subjected to large disturbances control actions need to be taken to steer the system away from severe consequences and to limit the extent of the disturbance. This is particular true if system is in an operating condition that makes it unusually vulnerable to catastrophic failure. In a previous PSERC project (S-19 that ended in 2005), we developed novel algorithms for each of the following steps:
- Detection of major disturbances and protective relay operations leading to cascading events. The detection algorithms improved capabilities of real-time fault detection and analysis to classify the impact of a fault towards initiating cascading outages.
- Wide-area measurement based detection and remedial control actions. The wide-area mitigation algorithms include methods for reliably extracting modal information on critical wide-area modes through real-time wide-area Phasor Measurement Unit (PMU) measurements. They also provide specific control actions to damp out the oscillations when problems are detected.
- Adaptive islanding with selective under-frequency load shedding. The adaptive islanding algorithms suggest methods for controlled islanding of the system should mitigation strategies fail.
The algorithms were shown to be effective using realistic computer models of test power systems. In this project, we focused on prototype implementations of those algorithms at collaborating PSERC member utilities.

| 08-20 | Preventing Voltage Collapse with Protection Systems that Incorporate Optimal Reactive Power Control
In recent years, new attention has been given to system disturbances that have cascaded
due to voltage instabilities and to unwanted relay operations. Unwanted relay operations
due to voltage instabilities and transients have not been well understood. In this project,
voltage instability phenomena were studied to develop a comprehensive approach for
mitigating the effects of voltage transients and instabilities on designed operation of a
protection system. The comprehensive framework covers monitoring, predicting, and
assessing system performance for secure power system operation. The developed
framework and methodology provide advanced tools use optimal control strategies that
can be used to avoid voltage collapse with respect to system-wide voltage instability and
undesired protection system operations. The project’s specific objectives were (1) to develop realistic models that accurately model voltage dynamics and their effects
on protective schemes; (2) to develop fast and flexible schemes for assessment of voltage stability and relay
status; and to develop optimal strategies to prevent voltage instability and maintain adequate
relay margins.
