摘要
随着可再生能源的利用越来越广泛,以可再生能源为动力的微网也越来越受到世界各国的关注。阐述了一种新型动态电压恢复器在微网中的运用,提出了基于神经网络的检测方法;对逆变器的控制采用模糊PI与常规PI相结合的控制方式,利用模糊推理方法实现PI参数的在线自整定,使控制器具有较好的自适应性。使用Matlab对系统进行仿真,仿真结果表明这种新型动态电压恢复器具有良好的动静态性能。
With the growing need of the energy worldwide, the microgrid which taken renewable energy as the motivation were paid attention by more and more countries. The application of the new type DVR in microgrid was mainly elaborated. A new test method based on neural network was presented. The combination of the fuzzy control and normal control strategy was adopted to control the inverter. The self-regulation of the PI parameters was realized by using the fuzzy inference. A sound self-adaption was achieved by the controller. The Matlab simulation shows that this new DVR has a good dynamic and static performance.
