Inter-area Oscillation Damping in Power Systems with Deep Penetration of Wind Energy

摘要

The rapid growth of energy demand in the recent years mandated exploiting energy resources alternative to the conventional fossil fuel-based resources. Nowadays, the renewable energy resources became a fundamental component of the current power systems. Numerous challenges are induced by these recent bulk systems such as low-frequency inter-area oscillations. This paper investigates three methods to damp inter-area oscillation in power systems with deep penetration of wind energy, which are: incorporating power system stabilizers in the automatic voltage regulator controls of the conventional generator, implementing a static var compensator in one of the system busbars, and implementing a high voltage dc transmission system to connect weakly-tied areas within the system. These methods helped increase inter-area oscillation damping when implemented in a modified system based on the classical two-area system.
