Simulation of Voltage Fluctuation and Flicker in Power Grid Power Quality

Simulation waveforms of voltage fluctuation and flicker in power grid power quality can be obtained through computer modeling. The simulation process, which typically involves MATLAB/Simulink environments or specialized power system analysis tools, can replicate various real-world scenarios of voltage fluctuations and flicker by incorporating grid physical characteristics and load behaviors. This includes simulating sudden load changes, grid fault conditions, and other disturbances using algorithms like RMS voltage calculation, flicker meter implementations (IEC 61000-4-15 standard), and dynamic system modeling. The simulation results provide valuable references for power system design, operation, and maintenance, contributing to enhanced reliability and stability. For power system engineers and researchers, understanding voltage fluctuation and flicker simulation techniques - including key functions for waveform generation, frequency analysis, and power quality assessment - is therefore essential for developing robust electrical infrastructure.
