| Popis: | Network delays and data-dropouts could have a significant impact on Cyber-Physical System (CPS). In this paper power grid with large-scale deployment of distributed and networked Phasor Measurement Units (PMUs) and wind energy resources is considered as an example of CPS. Modeling and simulation studies are done in a power system with 151 dynamic states for stabilizing electromechanical oscillations using remote PMU signals under different rates of data dropout, fault locations, and different degrees of nonlinearity. To that end a centralized state-feedback controller is designed to modulate the current references of Doubly Fed Induction Generator (DFIG)-based wind farm (WF). Modeling adequacy studies of a representative subtransient model of the grid and the averaged model of DFIG-based WF along with the representation of packet drop in the communication network by a Gilbert-Elliot model and Bernoulli model is performed. |
