Abstract

The goal of this research work is to propose a robust and efficient methodology for the multiobjective optimal continuation power flow. The continuation power flow is based on obtaining a continuum of Power system operating points for variable load and generation, allowing the analysis of operation conditions for each point and the determination of the maximum loading possible for which the system is still stable. The merging of continuation power flow and optimization procedures takes into account that the available control variables can be adjusted for each operating point, so as to optimize the operating conditions according to some criterion. Actually, more than one criterion may be optimized, and the procedure becomes multiobjective, requiring multiobjective programming tools. This computational tool allows a detailed analysis of power systems' behavior regarding many operation aspects, including voltage stability. Tracking the voltage profile and the voltage stability security margins are critical aspects for the secure operation of modern power systems that are permanently stressed (AU)
