This paper presents a new optimization tool-based population parameter called Harris hawks optimizer (HHO) and its application study to fine-tune the gains of well-designed proportional-derivative proportional-integral (PD-PI) cascade control to suppress the load frequency control (LFC) issues. The HHO based PID and PD-PI controllers are broadly implemented at two models with many circumstances for each model to ensure the effectiveness and the robustness of the proposed scheme at a high load disturbance, nonlinearity, and some critical parameters associated with the interconnected power system. First, a two-area non-reheat power plant is implemented, and the gains of PID and PD-PI controllers are adjusted using the proposed algorithm. In order to introduce extra realistic challenges, the governor-dead band is also modeled to ensure the robustness of the HHO/PD-PI in handling nonlinearity properties. Furthermore, to guarantee the suitability of the proposed HHO/PD-PI, a model with a mixture of power plants is carried out with and without the HVDC link, which is raised for the practical problems of LFC. Simulation results proved that; the proposed techniques HHO/PID and HHO/PD-PI provide superior performance compared to other reported strategies such as DE/PID, TLBO/PID, IGWO/PID, multi-objective/PID, and TLBO/2DOF-PID controllers. Finally, the dynamic investigation has also been completed using the random load pattern in system model-2, which shows the superior performance of HHO/PID and HHO/PD-PI schemes.

基于Harris Hawks的PD-PI级联控制的互联电力系统自动LFC优化算法

本文提出了一种新的基于优化工具的总体参数,称为哈里斯·霍克斯优化器(HHO),其应用研究用于微调精心设计的比例微分比例积分(PD-PI)级联控制的增益,以抑制负载频率控制(LFC)问题。基于HHO的PID和PD-PI控制器广泛应用于两种模型,每种模型都有很多情况,以确保所提出的方案在高负载干扰,非线性以及与互连电力系统相关的一些关键参数下的有效性和鲁棒性。首先,建立了一个两区域的非再热电厂,并使用所提出的算法来调节PID和PD-PI控制器的增益。为了引入额外的现实挑战,调节器死区也经过建模,以确保HHO / PD-PI在处理非线性特性时的鲁棒性。此外,为了保证所提出的HHO / PD-PI的适用性,在有和没有HVDC链路的情况下,建立了具有混合动力装置的模型,这针对LFC的实际问题提出了此模型。仿真结果表明:与其他已报告的策略(例如DE / PID,TLBO / PID,IGWO / PID,多目标/ PID和TLBO / 2DOF-PID控制器)相比,提出的技术HHO / PID和HHO / PD-PI提供了卓越的性能。最后,还使用系统模型2中的随机负载模式完成了动态调查,结果表明HHO / PID和HHO / PD-PI方案具有优越的性能。在有和没有高压直流输电的情况下,建立了具有混合动力装置的模型,这对于LFC的实际问题提出了。仿真结果表明:与其他已报告的策略(例如DE / PID,TLBO / PID,IGWO / PID,多目标/ PID和TLBO / 2DOF-PID控制器)相比,提出的技术HHO / PID和HHO / PD-PI提供了卓越的性能。最后,还使用系统模型2中的随机负载模式完成了动态调查,结果表明HHO / PID和HHO / PD-PI方案具有优越的性能。在有和没有高压直流输电的情况下,建立了具有混合动力装置的模型,这对于LFC的实际问题提出了。仿真结果表明:与其他已报告的策略(例如DE / PID,TLBO / PID,IGWO / PID,多目标/ PID和TLBO / 2DOF-PID控制器)相比,提出的技术HHO / PID和HHO / PD-PI提供了卓越的性能。最后,还使用系统模型2中的随机负载模式完成了动态调查,结果表明HHO / PID和HHO / PD-PI方案具有优越的性能。IGWO / PID,多目标/ PID和TLBO / 2DOF-PID控制器。最后,还使用系统模型2中的随机负载模式完成了动态调查,结果表明HHO / PID和HHO / PD-PI方案具有优越的性能。IGWO / PID,多目标/ PID和TLBO / 2DOF-PID控制器。最后,还使用系统模型2中的随机负载模式完成了动态调查,结果表明HHO / PID和HHO / PD-PI方案具有优越的性能。
