Abstract

In this paper, a seagull optimization algorithm (SOA) based 3-Degree-of-freedom (DOF) proportional-integral-derivative (3DOFPID) controller is suggested for load frequency control of multi-area interconnected power system (MAIPS). The considered MAIPS comprises of two areas with Thermal-Hydro-Nuclear generation units in each area. Analysis has been carried out by subjugating area-1 of MAIPS with a step load disturbance (SLD) of 10%. The sovereignty of presented SOA tuned 3DOFPID in regulating the stability of MAIPS is revealed upon comparing with the performances of 2DOFPID and conventional PID controllers. MIPS is analyzed dynamically without and with considering the nonlinear realistic constraint of communication time delays (CTDs) to demonstrate its impact on load frequency control performance. Simulation results disclosed that, MAIPS dynamical behavior is slightly more deviated up on considering CTDs and is justified.

具有时滞的多区域互联电力系统负载频率高阶自由度控制器

本文提出了一种基于海鸥优化算法(SOA)的3自由度比例-积分-导数(3DOFPID)控制器，用于多区域互联电力系统(MAIPS)的负荷频率控制。所考虑的MAIPS包括两个地区，每个地区都有热水核能发电机组。采用10%阶跃负载扰动(SLD)控制maps的1区进行分析。通过与2DOFPID和传统PID控制器的性能比较，揭示了SOA调优3DOFPID在调节maps稳定性方面的主权。对MIPS进行了动态分析，分析了在不考虑和考虑通信时延非线性现实约束的情况下MIPS对负载频率控制性能的影响。仿真结果表明，在考虑CTDs的情况下，MAIPS的动力学行为略有偏差，是合理的。
