  1. Present Day Problems • Low Peak Frequency • High Off-Peak Frequency • Wide Frequency Fluctuation • Damage to Generating • Plants and Consumers’ • Equipment • Merit Order not followed • - Optimizatn. Oppor. Lost • Perpetual Operational and • Commercial Disputes

  2. Apparent Reasons • Over-drawal in Low Frequency • Reluctance to Back-down • Governor Action Supressed • on Most Units • No Spinning Reserve • No Frequency Response • Inadequacy/Low Availability of Generating Capacity : Widening Gap • Reactive Power Drawals • Back-log in Capacitor Installation • UFR Load Shedding - Ineffective for Tackling Contingencies

  3. UNDERLYING CAUSES • Unscientific Tariff Structre • No Disincentive for Hurting the Grid • Conflict With Merit Order • Inappropriate Criteria for Judging Plants’ Performance • Compounding effects of frequency fluctuations • No formal Scheduling Process for Fixing Datums for Generation and Drawal Levels • No Clear Demarcation of Scheduling and Despatch • Regional Energy Accounting In Daily/monthly MU, Disregarding TOD And/or System Situation (Freq)

  4. THE REMEDY • Maximization Of Generation During Peak- load Hours And Load Curtailment Equal To The Remaining Generation Deficit • Backing Down Of Generation To Match The System Load Reduction During Off-peak Hours • Putting All Generating Units On Free-governor Mode Operation • Installation Of Capacitorss To The Required Extent • Absorbtion Of Vars During Off-peak Hours • Incorporation Of Effective Automatic Load-shedding
