摘要

本文研究了基于改进差分进化(MDE)算法的比例-积分-微分(PID)控制器在两区电力系统自动发电控制(AGC)中的动态性能设计和分析。为了验证所提出的方法,考虑了两区再热系统与PID控制器的集成。为了获得最优的动态性能,将设计问题描述为单个优化问题,即应用MDE对控制器增益参数进行微调。对于所提出的MDE优化策略,本文考虑了基于时间积分乘以绝对误差(ITAE)的目标函数。与其他基于随机的优化技术相比,该方法的性能得到了更好的证明。进一步验证了该方法在大范围的系统参数变化下具有较好的稳定性。最后,负荷变化研究的结果支持了该方法实时实现的可能性。

Design and analysis of automatic generation control of two area power system based on modified differential evolution algorithm
This manuscript deals with the design and analysis of dynamic performance of Modified Differential Evolution (MDE) algorithm based, Proportional-Integral-Differential (PID) controller for Automatic Generation Control (AGC) of two area power system. For justifying the proposed approach, reheat thermal system of two area integrated with PID controllers is considered. To obtain an optimum dynamic performance, the problem statement for design is framed as a single problem of optimization to apply MDE and finely tune the controller gain parameters. For the proposed MDE optimization strategy objective function based on the Integral of Time multiplied by Absolute Error (ITAE) is considered in this study. The proposed approach's enhanced performance is justified by showing better results as compared to other stochastic based optimization techniques. Furthermore, to validate the ability of the approach to perform with better stability under wide range of system parameter variation. Finally, the possibility of real time implementation of the proposed approach is supported with results from the load variation studies.
