摘要
Abstract
To solve the harmonic distortion problem and multiple uncertainties existing in the distribution network, the optimal configuration method of the distributed generators ( DGs) was employed, with harmonic distortion limits taken into account and uncertainties denoted by interval numbers.The cost of electricity, the network loss and the voltage stability were taken as the optimization indexes of the DG model, the harmonic distortion limit was added as a con-straint on the basis of meeting the security constraints of the distribution power flow, and then a multi-objective opti-mization model was established.Finally, the method of technique for order preference by similarity to ideal solution ( TOPSIS) based on interval mathematics was used to analyze the influence of uncertainties quantitatively, and the combination of it with the nondominated sorting genetic algorithm ( NSGA) was used to obtain the optimal configura-tion scheme of DG.The simulation results showed that this method could decrease the harmonic distortion rate effec-tively, and realize the integrated optimal performance of the generation power benefit and power quality.关键词
