Abstract

Electromechanical disturbances are caused by an imbalance between power supply and demand at any location of an electric grid. However, the associated propagation delay phenomenon is generally observed in large-scale interconnected power systems, and the transient effect of large changes in load or in generation can be felt over a wide geographic area. In the first part of this paper, background material will be covered to motivate the research ideas being pursued. In particular, focusing on the reason why the same amount of power imbalance, in a system with higher renewable penetration, can cause larger and more widespread frequency excursions. In the second part, a 9-bus system is introduced, and the transient response is studied with non-linear differential-algebraic equations, and then with a linearized approximation. Frequency-domain analysis of the transient response is also presented. Lastly, some relevant work in progress is touched upon, followed by concluding remarks.
