Electricity Market Structures to Reduce Seams and Enhance Investment (M-9 Report)
Description
Our research explored these two contemporary issues: (1) enhancing economically efficient trade across neighboring electricity control areas and (2) structuring forward markets to facilitate adequate efficient investment in electric supply infrastructure. Both topics raise fundamental questions about the proper design of markets when substantial costs are incurred for developing new production capacity and/or for transporting the product. Economic theory is sparse on these subjects. Given two unique attributes of electricity, that it can’
t be stored (optimal supply over time is simpler with storage) and that its reliability has public-good aspects that must be regulated, the need and opportunities for further improvement in electricity market designs are not surprising. Our theoretical analysis of spatial competition suggests that introducing arbitrage across boundaries can improve the competitiveness of adjacent markets, but that perverse flows from high- to low-priced areas may not be totally eliminated by that spatial competition when transport costs matter. These hypotheses were confirmed by our subsequent experimental trials. Theoretical analyses of the effect of forward markets on investment suggests that if they are conducted before the lead time needed to plan and construct new physical facilities, they can enhance the competitiveness and lower prices in the subsequent spot markets. Again our experimental trials confirmed these results where the forward markets are voluntary and accommodate financial arbitrage.

Real-Time Security Assessment of Angle Stability and Voltage Stability Using Synchrophasors (S-31 Report)
Description
This project examines the use of Phasor Measurement Units (PMUs) to assess angle and voltage stability in real time. The objective is to investigate how synchronized phasor measurements can be used to detect the loss of stability in real-time operations, be it angle stability or voltage stability. PMU deployment is becoming a common practice across the nation. Although the number of installed devices has quickly grown in the past few years, the development of applications to make use of PMU data has not been at the same pace. This project also analyzes how PMU data can be used to detect proximity to angle instability and voltage instability by monitoring some key PMU measurements. In Part I, multiple algorithms are proposed for detecting and mitigating angle instability by triggering generation and possibly load shedding schemes whenever needed. In Part II, a model that infers how far the system is to a voltage collapse is developed.

Implementation Issues for Hierarchical State Estimators (S-33 Report)
Description
There is renewed interest in situation awareness for an entire interconnection because of the cascading blackout of August 2003 which affected an area that is not covered by any one control center. In fact, a recent DOE/FERC report on the monitoring of the entire North American grid recommends use of interconnection-wide monitoring centers. As cited in the report, such centers will be made possible when enough phasor measurement units for time-synchronizing the data exist across an interconnection. Operationally, the local monitoring and state estimation results can be moved up through the reliability coordinators to an interconnection-wide monitoring center. If the use of interconnection-wide monitoring centers becomes feasible, the financial and reliability benefits will be quite substantial. Another real benefit will be that a real-time model of the whole interconnection could also be made available for local decision-making. Two parallel investigation paths were pursued in our research.
The overall conclusion is that state estimator results improve directly in proportion to the amount of real-time data exchanged. Also, if more data is exchanged, the external model can be represented in more detail than the present practice of equivalencing at the boundary. The phasor measurements have the added advantage of being time-stamped. If such synchrophasor data from the external model can be compared with synchrophasor data in the internal system, then the errors due to time-skews can be controlled.

Comparative Characterization of Parallel Distribution Sensors Under Field Conditions (T-35 Report)
Description
Under this PSERC project, researchers consulted with advisor utilities to determine commonly used varieties of alternative sensors. After reaching consensus on sensor selection, researchers installed a three-phase set of each selected model alongside a three-phase set of conventional CTs and PTs on an in-service, 12.47-kV distribution feeder. Over an extended period of time, the outputs of these devices were monitored with high-fidelity data-recording devices. These devices recorded multiple steady-state and transient electrical signals, including several overcurrent faults. Waveforms recorded simultaneously from the multiple sensors were analyzed in the time and frequency domains. Analysis focused on relative characterization of the sensors, using the conventional CT and PT signals as the benchmark. In general, voltage waveforms from the alternative sensors were similar to those of PTs, but current waveforms from the alternative sensors differed substantially from their CT benchmark. The generalized conclusion from this project is that utilities should not assume that any particular sensor has performance adequate for any particular function, without first carefully studying the requirements of the function and the performance of the sensors under consideration. In some cases, a sensor’
s published specifications may be inadequate for making an informed decision.

Technical and Economic Implications of Greenhouse Gas Regulation in a Transmission Constrained Restructured Electricity Market (M-21 Report)
Description
Greenhouse gas limits are already in effect in parts of Europe and North America, and more are expected in the near future. Electric power systems operating under these restrictions are required to limit their production of green house gases. Limits are implemented in one or more of several ways including a carbon tax, a carbon cap and trade system, and renewable portfolio standards. In this research we investigate the effects on an electric power system operating under such regulations. The three parts of the report are (1) AC Optimal Power Flow Studies in Reduced-Carbon Electric Power System Operations;
(2) The Impact of Alternative Greenhouse Gas Regulation on the Performance of Congested Electricity Markets in the Presence of Strategic Generators and Demand Response;
and (3) Generation Scheduling Problem Considering Carbon Dioxide Allowance Market.

The 21st Century Substation Design (T-37 Report)
Description
The purpose of this study is to create a vision of the future substation. To create this vision, various technical, economical and environmental criteria, such as reliability, cost, interoperability, re-configurability, security, controllability and flexibility need to be considered. Those criteria require use of new design methodologies quite different from the existing philosophy. The design strategies are focused on reducing cost while maintaining the performance, or maintaining cost while improving performance.
Three design approaches to meet different scenarios requirements and needs are considered: Retrofit existing substation design. This approach assumes retrofitting existing substation communication protocol, intelligent electronic devices, power apparatus, and operating standards to improve the overall performance or reduce cost without disrupting the continuity of service. Implement new substation design. This approach assumes designing the functionality and selecting the specific apparatus and IEDs to meet the demand of 21st century, using off-the-shelf products. In this approach, a new layout of substation equipment that illustrates innovative options for “ fusion” between power apparatus and infrastructure for monitoring, control and protection is proposed. Green field design. This approach assumes designing future substation that gives best solution to every criteria of the 21st century substation design including the optimization of the profit and system operation/cost, using completely new techniques, protocols, and apparatus.

Using PMU Data to Increase Situational Awareness (S-36 Report)
Description
With the large-scale deployment of PMUs in the U.S. and worldwide, a recurring theme has been the question of how to best extract useful “ information” or “ knowledge” from the very voluminous data that PMUs provide. While the direct control center display of PMU-based data is certainly important, particularly bus voltage angle values, this project focused on techniques the go beyond direct display of the raw PMU data. That is, the project focused on how information could be extracted from the PMU data, and then how this information could be used to improve power system situational awareness. Five different aspects of the problem are considered.

Improved Investment and Market Performance Resulting from Proper Integrated System Planning (M-18 Report)
Description
This report accomplishes several objectives. It lays out a desired sequence of having some forward markets placed earlier than the earliest commitment lead-time required for physical investment, of having regular subsequent markets to provide liquidity and to respond to updated expectations (and planning), and of laying out and making transparent the planning process and making explicit the criteria for expanding transmission capacity, where and when.
It also reviews some of the existing forward procurement markets, showing how particular details of auction structure may lead to anomalous results. A case is made to allow purely financial participation in forward markets, both to increase liquidity and reduce the potential for exercises of market power, up until the latest time when only physical participation will provide adequate assurance that ample steel will be in the ground to keep the lights on. And especially in highly congested regions where significant investment in new generation and/or transmission is likely to alter those patterns of congestion and locational price differences, any subsequent attempt to alter pricing zones must have the process and criteria for change laid out well ahead of time. Finally, it is recognized that potential changes in public policy and regulation may be the most unpredictable factor, upsetting both markets and planning. That is why it is important to have a scheduled process in place to consider those potential changes (e.g. whether about the environment, conservation incentives, the use of renewables or about siting criteria and decision-making) as well so they can be factored routinely into planning and market decisions.

Fast Simulation, Monitoring and Mitigation of Cascading Failure (S-32 Report)
Description
Cascading failure occurs when an initial disturbance in a power transmission system propagates to cause a widespread blackout. Large cascading failures are not frequent, but they have substantial risk due to their large societal costs. This project has pursued advances in methods to address cascading failure risk, particularly fast simulation for online support for operators, fast computation of emergency islanding control to mitigate cascading, and methods to monitor and quantify cascading risk from recorded or simulated data. There are three parts to the report:

System Protection Schemes: Limitations, Risks, and Management (S-35 Report)
Description
The objective of this research is to provide a structured framework for identifying limitations of SPS deployment within a system, and assessing SPS risks and develop proper standards and practices for maintaining SPS reliability over its lifetime. One of the highlights of the report is the unique assessment framework proposed based on both a process view and a systems view to identify risks and associated consequences for SPS. The process view based framework will view SPS in terms of a process which considers all the building blocks starting with the actuating signals, the equipment and logic used to operate on those signals, communication equipments and so on till the final action. The system view framework will view SPS in terms of its position in and impact on the power system in which it exists. This framework proposed is one of the significant contributions of this report, as even though a particular SPS design may appear quite reliable from the process view, it may not be so from system view due to the prospect of failures from interactions among many SPS in the system. So the system view risk assessment framework addresses such critical issues, which otherwise could cause cascading and catastrophic system consequences.
