The importance of good practice in managing oscillatory stability in an interconnected power system network is discussed. The maintenance of oscillatory stability is critical to avoiding potentially serious grid disturbances. Tools for dynamic modeling of power systems have long been available and remain an essential part of tackling power system instabilities. Dynamic modeling tools include a mathematical representation of the network, generation and loads that adequately reproduces the power system's response to disturbances. Many oscillation problems can be resolved by improving damping controls at generators and other active controls for damping. Maintaining a standard of about 2-3% damping normally provides an adequate margin of oscillatory stability.
