摘要

在综合电力系统中，负载频率控制一直是输送优质电力的一个关键方面。本文提出了一种优化调节的比例-积分-微分（PID）控制器，以消除由意外负载波动引起的频率误差，同时确保联络线功率交换。此外，还研究了具有发电率约束和调速器死区等非线性的三区域电力系统。为了调整PID控制器的参数，采用了改进的灰太狼优化（IGWO）。将优化后的PID控制器的动态响应与遗传算法（GA）、粒子群优化算法（PSO）和正弦余弦算法（SCA）的结果进行了比较。

Load frequency control in three-area single unit power system considering non-linearities effect

Load frequency control is always a crucial aspect in delivering quality power in integrated power system. This paper proposes an optimally tuned Proportional-Integral-Derivative (PID) controller to remove frequency errors caused by unexpected load fluctuations while ensuring tie-line power exchange. Moreover, the threearea power system with non-linearities such as Generation Rate Constraint and Governor Dead Band has been investigated. For tuning the parameters of PID controller Improved Grey Wolf Optimization (IGWO) has been used. The dynamic response of optimized PID controller have been compared with the result obtained from Genetic Algorithm (GA), Particle Swarm Optimization (PSO), and Sine Cosine Algorithm (SCA).
