Electric Power System Monitoring and Control
This Minitrack focuses on topics related to the ability of complex systems such as power systems to survive disturbances with minimal impact on performance. Specific topics include: Steady-State and Dynamic Security Assessment; Available Transfer Capability (ATC); State Estimation; Security-Constrained Optimal Power Flow; Sensor Applications; Large-Scale Real-Time Control; and related technologies.
Session 1: Sensor Networks
and Data Integration
Session Organizer M. Begovic
Sensor networks are an emerging technology that relies on a set of monitoring and communication devices distributed over the region of interest (in our case, power system). Devices (such as phasor measurement units, or distribution network monitors) are tied to a backbone command network, which can be wireless or wired (when speed is of importance). In order to maximize the network performance (which can be tied to a multitude of objectives), various forms of data fusion can be exploited at the cost of somewhat higher communication and computational burden.
Session 2: Advanced Real-time Measurements
Session Organizer Joe Eto
The North American Synchro-Phasor Initiative (NASPI) is a collaboration among utilities, ISOs/RTOs, NERC transmission companies, researchers and vendors to implement a wide-area synchro-phasor network in all four North American interconnections. The mission statement of the NASPI, to create a robust widely available and secure synchronized data measurement infrastructure over the eastern interconnection with associated analysis monitoring tools for better planning and operation, and improved reliability. This session will focus on aspects of the research being conducted in support of NASPI such as the collection, analysis, and application of these measurements, data protocols, communication, and integration, topology processing, state estimation, security margin assessment, alarming, and visualization.
Session 3: EMS Applications
Session Organizer: Tom Overbye
Restructuring in the electric power industry has led to the creation of large-scale Reliability Coordinators (RCs) with the purpose being better coordination of the security and reliability of the high voltage transmission grid. Furthermore, partially as a result of the August 14th, 2003 blackout, there has recently been an increased desire for better inter-RC coordination in order to provide better situational awareness of the state of the a large portion of the interconnected transmission system. The focus of this session is the energy management system(EMS) applications needed to provide this increased wide-area situational awareness. Desired papers would focus on traditional or new EMS applications with an emphasis on the changes needed to handle such large systems. Example topics include state estimation, contingency analysis, security constrained optimal power full, and wide-area visualization.

Decentralized markets are very effective at revealing preferences and costs, spurring efficiency and providing powerful incentives for technological innovation, when the commodity traded is a private good. Electricity delivered over a wired network, however, has many public good aspects when it comes to service quality and reliability, and the location, type and operation of generation facilities have profound environmental consequences whose management for the benefit of society also is a public good. Securing the best outcomes from a well-designed combination of market and engineering-planned mechanisms is the subject of this mini-track with sessions that focus on: 1) Sustainability and the environmental consequences of electricity supplies, 2) Reliability of the integrated system and customer impacts, and 3) the Dynamics of Technological Innovation as affected by institutional/market structures.
Session 1. Sustainability: Renewables, Carbon and Nuclear
Session Organizer: Tim Mount
Given the increasing public concerns about global climate change, different strategies for reducing the emissions of carbon dioxide from burning fossil fuels are currently being considered. These strategies have profound implications for electric utilities as the nation's largest user of coal. Choices include using fuels more efficiently (e.g. combined heat and power), burning coal more cleanly (e.g. IGCC with arbon sequestration), and substitutes for fossil fuels such as renewable energy and nuclear power. This session will discuss the types of incentives needed to make these strategies economically viable as an alternative to the industry's current plan to build a series of traditional pulverized-coal plants.
Session 2. Markets and Reliability of Supply
Session Organizer: Richard Tabors
The electric sector, worldwide, has evolved a myriad of complex market structures to deal with issues of short run scheduling of generation through long term capacity adequacy. In addition, markets for physical transmission and financial transmission rights are available through highly structured System Operator auctions as well as through a limited number of long-term physical auctions of individual controllable transmission paths. That advent of markets in NOx, SOx and increasing expectation of sophisticated CO2 markets has focused the attention of the financial as well as energy communities. The objective of this session is provide a forum for papers that focus attention on the operation of alternative market structures that provide for efficiency, reliability and security of supply as well as sustainability. The focus of the session will be upon the electric power sector with specific attention to evolution of electricity markets in Europe, North America and the Asia Pacific region (Australia, New Zealand and Singapore).
Session 3. Alternative Technologies
Session Organizer: Judy Cardell
The electric power system of the future will certainly contain new sources of energy such as wind, geothermal, and photovoltaics in order to embrace the Nations need for energy independence and the environments need for sustainability. The grid will be required to accommodate new load such as plug-in hybrid vehicles, and it would gladly embrace new storage technologies were they to become available. All-in-all, the grid of the future will have to be more flexible, controllable, and less vulnerable to uncertainty that the one that exists today. This session will focus developments in alternative technologies, focusing on the integration of small scale and distributed technologies into both markets and system operations, and including microgrids, plugable hybrid vehicles and demand response technologies.

This Minitrack focuses on topics related to advanced control concepts to enhance reliability, and cyber security issues associated with operating the future electric power infrastructure. The increasing reliance of the electric power industry on information technologies introduces a new class of cyber vulnerabilities and threats to the electric power infrastructure that are only beginning to be effectively addressed through common industry standards and best practices. We will explore the application of these technologies that are being considered to enhance the reliability of the modern electric power grid, and the associated cyber security issues associated with these and related technologies.
Session 1. Control System Cyber Security
Session Organizer: Carl Gunter
Networked computer systems are increasingly used to support the operation of electric power grids and energy service providers. Many types of Intelligent Electrical Devices (IEDs) have been introduced in substations and networked through Supervisory Control and Data Acquisition (SCADA) systems. Millions of power meters are being upgraded to Advanced Meter Infrastructures (AMIs) that provide for networked access to meter data over wireless links and the Internet. These advances have exposed electric power systems to the numerous cyber security threats that plague other types of computers and networks. These threats can be addressed to some degree by sound application of existing cyber security techniques, but there are also new types of problems specific to control systems in general and electric power systems in particular. This session will consist of research advances in technologies that will provide the necessary cyber security for such systems.
Session 2. Advanced Communication/control for Reliability
Session Organizer: Ian Dobson
The electric power grid is a complex networked infrastructure subject to rare but costly blackouts involving cascading failures, operating procedures, and a variety of dynamical interactions. Bulk power transactions are increasing in volume and variety that stress the grid in new ways and physical grid upgrade remains constrained by economic, policy, and environmental considerations. This session will address innovations in power system operation and control to improve reliability enabled by advances in monitoring, modeling and computation.
