RELIABILITY OPTIMIZATION OF COMPOSITE POWER SYSTEMS INCLUDING VOLTAGE STABILITY UTILIZING AN EVOLUTIONARY ALGORITHM

摘要

In this paper a methodology to optimize the reliability of a composite power system by means of an evolutionary algorithm is developed. The methodology uses the optimal assignment of shunt compensation in nodes and parallel redundancy in lines with highest participation in stationary voltage stability, using the technique of the Minimum Singular Value (MSV) applied to the reduced Jacobian matrix of the system, economic constrains are considered in the assignment of compensation and redundancy in lines. The methodology is applied to an eastern area equivalent of the Mexican grid. The results are presented for several parameters for the tuning of the evolutionary algorithm, showing the robustness of the evolutionary algorithms, as a powerful tool for the solution of complex optimization problems.
