Abstract

This paper presents an intelligent droop control scheme for DC/DC Boost converter which is used as voltage regulator in islanded DC Microgrid. This approach is a combination of Fuzzy Inference System (FIS) and Genetic Algorithm (GA) which is used to improve voltage regulation and equal power sharing between the DGs under abrupt load changing while the power losses is low. The propose control performance is compared with the other typical droop control approach. The simulation results are further verified by SIMULINK in MATLAB/SimPowerSystems. The proposed control scheme on this paper has two important advantages, online approach by using Fuzzy Inference System design and its lower dependence on the mathematical model of the network.

一种改善孤岛直流微电网电压调节和电力均分的智能下垂控制方法
本文提出了一种用于孤岛直流微电网稳压的DC/DC升压变换器的智能下垂控制方案。该方法将模糊推理系统(FIS)与遗传算法(GA)相结合,在低功率损耗的情况下,提高负载突变情况下dg之间的电压调节能力和均分功率。并与其他典型的俯仰控制方法进行了性能比较。通过MATLAB/SimPowerSystems中的SIMULINK进一步验证了仿真结果。本文提出的控制方案有两个重要的优点,一是采用模糊推理系统设计的在线方法,二是对网络数学模型的依赖性较低。
