Lecture Topic:
Power Grid Stability in the Era of Renewable Energy: Synchronization, Dynamics, and Power System Stability
Abstract:
As renewable energy sources such as wind and solar power are increasingly integrated into power grids, maintaining grid stability has become a greater challenge. Traditional power plants provide a steady output and natural inertia, whereas renewable energy sources are highly variable and uncertain. This requires new approaches to synchronization and power grid stability.
This lecture will explain the importance of power grid stability, the role of synchronization in preventing blackouts, and introduce the swing equation as a fundamental tool for understanding power system dynamics. Using a two-bus system as an example, Dr. Oh will demonstrate the application of the swing equation and discuss various stability analysis methods, including the Lyapunov function approach, time-domain simulation, and analytical solutions to the swing equation. The lecture will also explore techniques for maintaining stability in power grids that incorporate both renewable and conventional power generation.
