Comparative analysis among Pareto, Pareto — Fuzzy logic and Pareto — Fuzzy logic PI for distribution networks with the presence of DGs

This paper presents the advantages of optimization algorithms and logical analysis algorithms for voltage and reactive power control on distribution networks with the presence of Distributed Generations (DGs). The problem is formulated as a multi-objective model that minimizes the variations of the voltage on the pilot bus using Pareto optimization, Pareto and Fuzzy, and Pareto and Fuzzy-PI. The proposed technique is applied to the IEEE 13-node test feeder with variable load and one DG. The results demonstrate the efficiency on the voltage variation when the techniques are combined.
