Purpose

This paper aims to suggest the parameter identification of load frequency controller in power system.

Design/methodology/approach

The suggested control approach is established using fuzzy logic to design a fractional order load frequency controller. A new suitable control law is developed using fuzzy logic, and based on this developed control law, the unknown parameters of the fractional order proportional integral derivative (FOPID) controller are derived using an optimization technique, which is being used by minimizing the integral square error. In addition, to confirm the effectiveness of the proposed control design approach, numerous simulation tests were carried out on an actual single-area power system.

Findings

The obtained results reveal the superiority of the suggested controller as compared to the recently developed controllers with regard to time response specifications and quantifiable indicators. Additionally, the potential of the suggested controller is also observed by improving the load disturbance rejections under plant parametric uncertainty.

Originality/value

To the best of the authors’ knowledge, the work is not published anywhere else.

基于模糊FOPID的电力系统负荷频率控制参数辨识

目的

本文旨在对电力系统负荷频率控制器的参数辨识提出建议。

设计/方法/方法

建议的控制方法是使用模糊逻辑来设计分数阶负载频率控制器。使用模糊逻辑开发了一种新的合适的控制律，并基于该开发的控制律，使用优化技术导出分数阶比例积分微分 (FOPID) 控制器的未知参数，该技术通过最小化积分平方误差来使用. 此外，为了确认所提出的控制设计方法的有效性，在实际的单区域电力系统上进行了大量模拟测试。

发现

获得的结果表明，与最近开发的控制器相比，建议的控制器在时间响应规范和可量化指标方面的优越性。此外，还可以通过改善工厂参数不确定性下的负载干扰抑制来观察建议控制器的潜力。
