Generally, a problem is discussed globally, where the mathematical model describing the physical phenomena is derived and the equations are solved with Matlab, in a step-by-step approach.

This study investigated students' modeling progress and strategies in a problem-solving simulation game through content analysis, and through supervised and unsupervised lag sequential analysis (LSA).

The DFIG and converter are in D-Q model technique. The DFIG based on wind energy conversion system in MATLAB/Simulink is also introduced in this paper.
