Abstract

modern power systems present an energy mix that incorporates an increasing number of power electronics based devices such as energy storage systems, solar power systems, high voltage direct current links, etc. These devices do not have inherent inertia like traditional systems to counteract frequency deviations during disturbances such as load imbalance. A virtual inertia controller in an energy storage system is presented in this paper to mitigate the frequency instability during system disturbances. Fuzzy logic control is proposed as an intelligent control technique to provide adequate inertia response to drive the system back to steady state during load disturbance. The system was modelled and analysed using MATLAB/SIMULINK software.

基于模糊控制器的现代多区域电力系统频率控制
现代电力系统呈现出一种能源结构,其中包含越来越多的基于电力电子设备的设备,如储能系统、太阳能发电系统、高压直流链路等。这些设备不像传统系统那样具有固有的惯性来抵消负载不平衡等干扰期间的频率偏差。本文提出了一种用于储能系统的虚拟惯性控制器,以减轻系统扰动时的频率不稳定性。提出了模糊逻辑控制作为一种智能控制技术,以提供足够的惯性响应,使系统在负载扰动时恢复到稳态。利用MATLAB/SIMULINK软件对系统进行了建模和分析。
