The investigation of invariance of the output of complex electric power system with application system’s embedding approach

The Invariance Determination of the Complex Electrical System Output of

“…with coefficients for the parameters of the electrical system mode. The synthesized controller (14) with matrices c and g with arbitrary numerical values of the elements must be designed so that the necessary technical requirements are provided in the dynamic system: stability, damping of low-frequency oscillations [10][11][12][13][14][15].…”

“…Figure 3 shows the characteristics of the change in the deviation of the angle of the first generator  1 =f(t), a stable, controlled (16) electrical system (Figure 3, A), with the synthesized parameters of the controller (15), and an unstable, unregulated EPS (10), (Figure 3, B).…”
