Abstract

LFC (Load Frequency Control) in power system is essential to normalize the frequency deviations in power system during unpredicted load perturbations. Novel 1 Plus Fraction ID (1 plus FID) Controller is recommended in this article to adjust the frequency fluctuations in a dual area thermal system with EV aggregators. The gains of projected 1 plus FID controllers are carefully chosen by Selfish Herd Optimization (SHO) in the presence of an abrupt disturbance of 10% in control area 1 utilizing integral time absolute error (ITAE) as the objective/fitness function. In the initial analysis the dominance of 1 plus FID controller is witnessed over the PID controller during 10% load deviation in control area 1. In the latter case the effectiveness of the projected 1 plus FID controller is certified by applying haphazard loading in control area 1. The examination of the system responses are presented to establish the ascendency of the projected SHO tuned 1 plus FID controller over existing PID controller on the basis of settling time, undershoots and overshoots.

基于SHO调优1 +分数ID控制器的LFC研究

电力系统的负荷频率控制(Load Frequency Control, LFC)是在负荷不可预测扰动下对电力系统频率偏差进行归一化的关键。本文推荐使用新型1 +分数ID (1 + FID)控制器来调节带有EV聚合器的双区域热系统的频率波动。利用积分时间绝对误差(ITAE)作为目标/适应度函数，利用自私群体优化(SHO)在控制区域1存在10%的突然扰动时，仔细选择预测1 + FID控制器的增益。在初始分析中，1 + FID控制器在控制区域1的10%负载偏差时优于PID控制器。在后一种情况下，通过在控制区域1中应用随机加载来证明预测的1 + FID控制器的有效性。通过对系统响应的检验，在稳定时间、欠调和过调的基础上，建立了预测的SHO调谐1 + FID控制器优于现有PID控制器的优势。
