ARIAS, Diego. Multi-objective Optimization of the Active and Reactive Power to PQ curve of the Power System Bus. Revista Técnica energía [online]. 2020, vol.17, n.1, pp.11-17. ISSN 2602-8492.  https://doi.org/10.37116/revistaenergia.v17.n1.2020.389.

In this work, a problem of multiobjective optimization of active and reactive power in the bars of the system is proposed, which considers the operating limits, the generation capacity, the reactive power reserves, the active power capacity, the transmission restrictions, and the voltage limits of the electric power system (SEP). The proposed multi-objective optimization problem is based on a combination of the objective function1: reactive power margin and the objective function 2: active power, in the bar subject to analysis of the SEP margin. From the multiobjective problem the Pareto Border is obtained, which represents the PQ curve (projection of the PV and QV curve on the plane) of the bar under analysis. The optimization problem model is applied to a test system for its validation and analysis of results. In this way, a reliable measure is provided to evaluate the voltage stability and the security of the system in electrical networks considering the maximum operating limits of the SEP.
