Updated Data for Use in G&T Reliability Models

        Chair:               A. A. Chowdhury, Mid-America Energy

Reliability models are becoming widely used throughout the world as the advantages of probabilistic methods over the deterministic approaches to planning, designing, operating and maintaining the electric utility systems have been recognized. The collection of power system outage data is thus an integral part of an effective reliability assessment system that provides the tools and information necessary to attain the objective of reliable electric service at the lowest possible cost. Accepted standard definitions for generation and transmission equipment availability data are imperative in order to permit the evaluation of historical performance based on availability or outages. This panel session will focus on the relevant technical and commercial aspects of generation and transmission equipment outage data reporting practices in the traditional and open access environment.

Experiences with Reliability Unit Commitment

Reliability Unit Commitment (RUC) is adopted widely by restructured electricity markets to maintain system reliability while minimizing the overall operational cost for committing additional units. Unlike Day-Ahead (DA) market which provides a financial platform for market participants to trade energy, RUC is vital to power system security in such a way that it ensures sufficient online capacity at the right location to satisfy the demand in real time. Specifically, RUC determines the commitment of additional resources as necessary beyond those already self-committed for bilateral contracts and committed by other markets (DA and AS), to meet the forecasted real-time demand plus Ancillary Service (AS) requirement. The process of RUC involves a Security Constrained Unit Commitment (SCUC) algorithm with a full network model to enforce transmission flows and bus voltages within limit and to meet the (N-1) system reliability criterion.

The intent of this panel is to exchange views on RUC's operational experiences and discuss the related challenges and its future outlook. Issues to be addressed include:
1. Development of accurate and effective models for special resources such as combine cycle units, wind units, and hydro units;
2. Ability to handle Load forecast errors;
3. Look-forward RUC studies: seven-day ahead, day ahead, and hour ahead;
4. Maintaining legitimate market price signals for Real Time Energy Market;
5. Providing positive market incentives by setting proper settlement rules;
6. Commitment decision between quick start units and units requiring longer start time;
7. Market Power Mitigation;
8. RUC optimization objective: Should incremental energy cost be as well considered?

Operation Challenges in Restructured Energy Systems
        Sponsored by:   Power System Operations Committee
        Chair:               E. Vaahedi, BCTC, Canada

The electric industry worldwide is undergoing a fundamental restructuring to deregulate key elements of the business and subject them to competition. This has resulted in the creation of the new institutions and players as well as profound changes in operation of the energy markets and the power system in the emerging market structures. In this panel session, executives responsible for system operations at a number of restructured energy systems provide a window on operation challenges they face.

Optimizing Value of Genco Assets in LMP Markets
        Sponsored by:   Power System Operations Committee
        Chair:               K. Le, PCI, Inc.

In the new LMP world, portfolio managers face a host of new challenges. This panel explores the key challenges facing portfolio managers, traders, and risk managers in the new LMP-centric world:
What are the main physical and financial impacts of the new LMP market on our generation fleet?
Do our schedulers have the tools to accurately forecast hourly loads and prices for the day-ahead and real-time markets?
How can our traders formulate bidding strategies that maximize the expected profits from both the day-ahead and real-time markets?
How should our risk managers formulate bidding strategies to reflect market mitigation rules?
How well can our trading team forecast costs, revenues, profits & losses, fuel consumption, and emissions for units that are scheduled by the ISO?
How can we make sure that the ISO day-ahead schedule meets our plant operational constraints (NOx, take-or-pay gas, etc…)?
How much money are we leaving on the table if we decide to self-schedule selected units?
How does a lower availability affect revenues and profits for our portfolio?
How can our traders determine that the ISO day-ahead dispatch is not "optimal" for specific units?
What is the best way to formulate hedging strategies for our assets in LMP markets?
How should we value FTRs in LMP markets?
Do we need to have our own shadow settlement software to check ISO invoices?

Decision Making Under Uncertainty

        Chairs:              L. A. Barroso, Mercados de Energia/PSRI
                                A. J. Conejo, Universidad de Castilla-La Mancha

Almost all energy-related decision making problems involve some level of uncertainty either on data availability, load and prices, investments, interface between regulated and competitive environments or even on the environment in which agents have to operate. The appropriate representation of the dynamic aspects of decision making as uncertainties are resolved over time (dynamic decision making) is also an important issue. This panel is aimed at creating an enlivened discussion on how to properly consider and model uncertainty in electricity markets, particularly on operational problems. Presentations will address diverse specific models and their applications as well as a description of the numerical procedures and strategies that have been developed for certain classes of stochastic programming problems. Outstanding contributors on uncertainty modeling, electricity markets and operational issues will present the state of the art of the subject, including modeling and computational issues, bidding strategies, operational problems, etc.
