It has been veri"ed that a controllable series capacitor with a suitable control scheme can improve transient stability and help to damp electromechanical oscillations. A question of great importance is the selection of the input signals and a control strategy for this device in order to damp power oscillations in an e!ective and robust manner. Based on Lyapunov theory a control strategy for da...

In this paper the dynamic performance of an Eletric Power System (EPS) under several levels penetration Utility-scale Solar Photovoltaic generation is discussed. Furthermore, control strategies are proposed, based on optimization indexes and pole placement control, which can mitigate impact UFV damping system electromechanical oscillations.

Major disturbances in power system can take place after power system elements such as generators, loads, or transmission lines are suddenly disconnected. Such disturbances can create so called “electromechanical wave oscillations” waves which propagate through transmission lines at much lower speed than speed of light. They can cause adverse effect on power system protective relays. In this pap...

A novel electromechanical chaotic oscillator is described that admits an exact analytic solution. The oscillator is a hybrid dynamical system with governing equations that include a linear second order ordinary differential equation with negative damping and a discrete switching condition that controls the oscillatory fixed point. The system produces provably chaotic oscillations with a topolog...

The proliferation of grid-connected converter interfaced energy sources in Smart Grids, enhance sustainability and efficiency as well minimizing power losses costs. However, concerns arise regarding the stability reliability future smart grids due to this wide integration electronic devices, which are recognized affect dynamic response system, especially during disturbances. For instance, apart...

Power system dynamic stability is one of key issues engineers face. Oscillations that regularly occur in the system, limit transmission capability network. The need to study power systems has been increasingly growing along with development and their grouping into large interconnections. focus this paper determining a synchronous generator, thus by applying general theory systems. Furthermore, ...

This paper presents a fuzzy logic controller for series reactance switching to damp power system electromechanical oscillations. A set of control rules are constructed and inference is provided by fuzzy logic reasoning. The knowledge base for the controller is established from observation of the dynamicrd behaviour of a simple power system and the general engineering knowledge about the system ...

Static Var compensator (SVC) is one of flexible AC transmission system (FACTS) elements mainly used for reactive power and voltage control in power systems. This paper deals with multi-modal electromechanical oscillations damping in the presence of severe disturbances. These oscillations include local modes, interarea modes and inter-plant modes. To enhance the damping of the oscillations, a co...
