Nowadays, the most widely used variable speed wind turbine type for units above 1 MW is doubly fed induction generator (DFIG). As the wind power penetration continues to increase, wind turbines are required to remain connected during grid faults to ride-through the faults. This paper gives a control oriented modeling of DFIG wind turbines by using causal ordering graph (COG). The control system consists...
This paper gives a control oriented modeling of an electrolyzer, as well as the ancillary system for the hydrogen production process, by using causal ordering graph. The control system has also been proposed to manage the power flow and hydrogen flow. The simulation results have highlighted the variation domains and dynamics of physical quantities.
A dynamic model of a micro gas turbine generator by using a causal ordering graph is proposed in this paper. This particular graphical representation is used to highlight the causal order of all mathematical equations. It is shown that the obtained model is interesting for developing a Matlab Simulink model and for designing the control strategy. In order to control the power flow a second model is...
