Abstract

Numerous renewable energy source (RES) plants have lately been added to modern power grids. Power electronics converter systems (PECS) have become key components in the structures of these RESs for grid integration. However, PECS-based RESs result in decreased power system inertia, which reduces as penetration increases. Load frequency controllers (LFCs) have enhanced the performance of current power grids based on PECS. As a result, this study provides an optimal LFC structure based on merging characteristics from standard Tilt-Integral-Derivative (TID) and fractional order-based proportional-integral-derivative (FOPID) controllers in a novel combined FOTID LFC technique. The recently announced slime mould algorithm (SMA) was used to optimize the parameters of the proposed LFC. The results of a two-area RES-based power grid simulation are utilized to validate the proposed TFOID controller and the SMA-based design optimization.

基于未来低惯量电力电子的现代电网LFC优化设计
许多可再生能源(RES)工厂最近被添加到现代电网中。电力电子转换系统(PECS)已成为电网一体化的关键组成部分。然而,基于pecs的RESs降低了电力系统惯性,随着渗透的增加而减小。负载频率控制器(lfc)提高了基于PECS的现有电网的性能。因此,本研究提供了一种基于融合标准倾斜积分导数(TID)和分数阶比例积分导数(FOPID)控制器特征的新型组合FOTID LFC技术的最优LFC结构。利用最近公布的黏菌算法(SMA)对LFC的参数进行了优化。利用基于双区域res的电网仿真结果验证了所提出的TFOID控制器和基于sma的设计优化。
