Prepared By: Mrs. Puja Gurav
Introduction
• • Definition of power system operation and control
• • Importance in reliable electricity supply
• • Key areas: Generation, Transmission, Distribution, Load
Structure of Power System
• • Generation
• • Transmission
• • Distribution
• • Load centers
Objectives of Power System
Operation
• • Maintain system frequency
• • Ensure voltage regulation
• • Load balancing
• • Economic operation
Types of Power System Controls
• • Real Power Control (Frequency Control)
• • Reactive Power Control (Voltage Control)
• • Load Dispatch
• • Economic Load Dispatch (ELD)
• • Automatic Generation Control (AGC)
Load Frequency Control (LFC)
• • Purpose: Maintain nominal frequency
• • Primary & secondary control loops
• • Area Control Error (ACE)
Voltage Control
• • Importance of voltage profile
• • Methods: Tap changing transformer, SVC, capacitor banks
• • Reactive power support
SCADA and EMS
• • SCADA: Supervisory Control and Data Acquisition
• • EMS: Energy Management System
• • Real-time data, alarms, decision support
Economic Load Dispatch (ELD)
• • Optimal generation scheduling
• • Cost minimization
• • Incremental fuel cost
• • Basic ELD equation
Automatic Generation Control
(AGC)
• • Real-time balancing
• • Tie-line power flow
• • Role in multi-area systems
Modern Trends in Power System
Control
• • Integration of renewables
• • Smart grid
• • Demand-side management
• • PMUs and WAMS
Case Study Example
• • 2012 India blackout
• • Impact of poor frequency and voltage control
Conclusion
• • Summary of control needs
• • Importance of automation and real-time response
• • Future of power systems with AI and IoT
