Load Frequency Control (LFC) of a Single Area Power System | MATLAB/Simulink Tutorial https://www.lmssolution.net.in/produc... Description : This video demonstrates the Load Frequency Control (LFC) of a single-area or isolated power system using MATLAB/Simulink. It explains how frequency deviations occur due to sudden load changes and how Proportional-Integral (PI) control restores the nominal frequency by regulating the generator’s mechanical input through governor–turbine dynamics. 🔹 What You’ll Learn: • Fundamentals of load frequency control in isolated systems • Modeling of governor, turbine, and generator-load dynamics using transfer functions • Step-by-step Simulink construction of the LFC block diagram • Comparison of open-loop vs. PI-controlled system responses • Controller tuning (Kₚ and Kᵢ) for faster settling and zero steady-state error 🔹 System Highlights: • Governor time constant = 0.2 s • Turbine time constant = 0.5 s • Generator–load time constant = 0.8 s • Step load disturbance ΔPₗ = 0.2 p.u. • Regulation constant R = 0.05 (gain = 20) • Simulation time = 60 s 🔹 Simulation Results: • Without control: Δf ≈ −0.01 p.u., slow recovery • PI (default): faster damping, smaller deviation • Tuned PI (Kₚ = 1.9, Kᵢ = 0.5): zero steady-state error within ≈ 20 s • High-gain PI (Kₚ = 7): fastest settling (less than 15 s) with smooth frequency restoration 🔹 Key Observations: • Open-loop LFC shows frequency drop after a sudden load increase • PI control eliminates steady-state error and improves transient response • Proper tuning of Kₚ–Kᵢ ensures zero frequency deviation and system stability 🔹 Applications: • Power system stability studies • Isolated grid or microgrid operation • Control system education and research • Benchmark for intelligent LFC (Fuzzy, ANN, PSO-PID) 📘 Keywords: Load Frequency Control, Single Area Power System, MATLAB Simulink LFC, Governor Turbine Generator Model, Frequency Deviation Control, PI Controller Tuning, Power System Stability, Isolated System LFC, MATLAB Power System Tutorial 🔖 Hashtags: #MATLAB #Simulink #LoadFrequencyControl #PowerSystem #ControlEngineering #PIDControl #RenewableEnergy #LMSsolution ============================================================ Whatsapp: https://wa.me/917904458501 Whatsapp: https://wa.me/918838943991 Email Id: support@lmssolution.net https://www.lmssolution.net.in/contact
