Abstract

This paper deals with integrated voltage and harmonics distortion control (volt/THD) for radial distribution feeders in planning issues, by means of the application of automatic voltage regulators (AVRs) banks and harmonic passive filters. A multiobjective genetic algorithm (SPEA2) improved using fuzzy logic is presented to solve the VOLT/THD problem, since it is a combinatorial multiobjective optimization problem. The expert knowledge is taken into account via fuzzy logic in order to reduce the search space using voltage regulators in standard units. According to the multiobjective optimization fundamentals, an optimal solution ensemble is obtained, which concomitantly represents the solutions to both objectives, in such way that the operational restrictions of systems are satisfied. Two objectives have been established: voltage level deviation and total harmonic distortion. An algorithm is applied to harmonic analysis in radial systems, with application of models compatible with practical data. The algorithm is evaluated for a known 34-bus feeder in the literature of the subject.

配电系统电压/电压问题的多目标优化

本文通过自动调压器组和谐波无源滤波器的应用，研究了径向配电馈线规划中的电压谐波综合失真控制问题。由于VOLT/THD问题是一个组合多目标优化问题，提出了一种利用模糊逻辑改进的多目标遗传算法(SPEA2)。通过模糊逻辑考虑专家知识，以减少在标准单元中使用稳压器的搜索空间。根据多目标优化的基本原理，得到一个最优解集合，该集合同时表示两个目标的解，从而满足系统的运行约束。建立了电压电平偏差和总谐波畸变两个目标。将一种算法应用于径向系统的谐波分析，并给出了与实际数据相适应的模型。该算法是评估已知34总线馈线在该主题的文献。
