Title of Presentation: Vision for a Holistic Power Supply and Delivery Chain

Abstract:

This will present a vision for a holistic power supply and delivery chain, which may be a

    more meaningful description of a Smart Grid. It will include a potential application to

    China based on the special characteristics and needs of China.

    The dramatic changes which are likely to occur in the electric power industry in the next

    10 years (e.g., expanded variable renewable resources, electric energy storage, plug-in

    hybrid electric vehicles, distributed resources, and others) place greater burdens on power

    system operators and planners. The power system of 20 years or even 10 years from now

    is likely to look quite different than today’s power system. And every function that power

    system operators and planners perform will be impacted by these changes. For this reason,

    the broad array of anticipated changes across the power delivery and supply chain

    directly affect grid operations and planning. The purpose of this presentation is to identify

    the most pressing research needs within the advanced grid operations and planning

    domain, as well as to describe a vision for a holistic power supply and delivery chain that

    addresses some of these research needs.

    One broad way to visualize a solution to the broad array of anticipated challenges in the

    industry is to envision an end-to-end system of power system monitoring, modeling,

    analysis, coordination, and control. This solution includes the power supply portion of the

    chain due to the impact of fuel price and availability on power grid operation and

    planning. In this system, data gathered through various means across the power system

    supports data monitoring and local analysis at substations, for example, as well as

    development of dynamic models of both generators and loads. Improved alarm

    management at both transmission owner and Regional Transmission Operator (RTO)

    control centers process data received from across the power system. At RTO control centers, this data and other information supports enhanced wide area coordination, dispatch, control, and when necessary, restoration. Planners use improved power system planning methods and dynamic generator and load models, while complementing the efforts of power system operators. Significant improvements are needed in all of these areas to realize this vision.
