    Q. 1) State importance / need of load forecasting. (May 16)

    a) Load forecasting is a technique used by power
    companies to predict the power or energy needed to
    balance the supply and load demand at all the times.
    b) Accurate models for electric power load forecasting
    are essential to the operation and planning of a utility
    c) Load forecasting helps an electric utility to make
    important decisions including decisions on purchasing
    and generating electric power, load switching, and
    infrastructure development.
    d) Load forecasts are extremely important for energy
    suppliers, ISOs, financial institutions, and other
    participants in electric energy generation,
    transmission, distribution, and markets.
    e) Short-term load forecasting can help to estimate
    load flows and to make decisions that can prevent
    f) Timely implementations of such decisions lead to
    the improvement of network reliability and to the
    reduced occurrences of equipment failures and
    g) The need for power varies from season to season,
    day to day, and even minute to minute. To ensure that
    an adequate supply of power is available to meet the
    demand, there must be a plan far into the future. Load
    forecasting is one of the planning processes used to
    evaluate the projected load.
    h) Forecasts of the load are used to decide whether
    extra generation must be provided by increasing the
    output of online generators, by committing one or
    more extra units, or by the interchange of power with
    neighboring systems.
    i) Similarly, forecasts are used to decide whether the
    output of an already running generation unit should be
    decreased or switched off, which is determined by
    generation control functions, such as scheduling, unitcommitment,
    coordination, and interchange
    j) Precise load forecasting helps the electric utility to
    make unit commitment decisions, reduce spinning
    reserve capacity and schedule device maintenance
    plan properly.
