Optimal simultaneous coordination of PSS and TCSC using multi objective genetic algorithm

الملخص EN

Power system stability enhancement via optimal simultaneous coordinated design of a power system stabilizer (PSS) and a thyristor-controlled series capacitor (TCSC) for electric power systems oscillations damping is investigated in this paper.

A SMIB system equipped with PSS and TCSC controllers is considered in this study.

Although these controllers are used for stabilization of power system oscillations but the system must preserve its stability when subjected to sever disturbances.

Therefore, the overall stability of the system should be considered.

To do so, in the present paper the problem of controllers design is formulated as a multi objective optimization problem.

Then the multi objective genetic algorithm (MOGA) is explored to solve this optimization problem.

Pareto method type of selection is used in the present MOGA approach.
