A hybrid system approach to static var compensator modeling and control

This paper proposes a hybrid model of Static var compensator (SVC) capturing the continuous and discrete behaviors of SVC in term of hybrid system and an approach to design a controller of SVC to maintain voltage of power system in normal range based on maximal controlled invariant set. The proposed SVC´s model is representable complex interactions between continuous dynamics and discrete events of SVC. The proposed controller is able to ensure the power system working in safe set despite the change of the grid parameters.
