Abstract

In this paper, the efficacy of flexible alternating current transmission (FACTS) devices such as static synchronous series compensator (SSSC) and Thyristor controller series compensator (TCSC) in maintaining the stability of interconnected power system (IPS) is presented. Initially, fractional-order (FO) type PID (FOPID) optimized with water cycle algorithm (WCA) is suggested as the secondary regulator. Multi-area realistic hydro-thermal (MARHT) system with the integration of a geothermal power plant (GTPP) in only area-1 is taken out for investigation. Analysis has been accomplished by laying a step load perturbation of 10% on area-1. However, the supremacy of FOPID has been demonstrated with PID and FOPI. Further, the devices of SSSC and TCSC are placed in conjunction with the tie-line for performance enhancement. Simulation results reveal the sovereignty of TCSC in perturbed conditions and battery energy storage (BES) devices are incorporated in both areas to attain improvement in system dynamical behaviour.

SSSC与TCSC装置在地电厂一体化互联电力系统负荷频率控制中的性能比较

本文介绍了柔性交流传输(FACTS)器件如静态同步串联补偿器(SSSC)和可控硅控制器串联补偿器(TCSC)在维护互联电力系统(IPS)稳定性方面的作用。首先，采用水循环算法(WCA)优化分数阶PID (FOPID)作为二级调节器。选取了仅在1区与地热发电厂(GTPP)集成的多区现实水热(MARHT)系统进行了研究。通过在区域-1上施加10%的阶跃载荷扰动来完成分析。然而，FOPID的优势已经被PID和FOPI所证明。此外，SSSC和TCSC的器件与联络线一起放置以增强性能。仿真结果表明，TCSC在摄动条件下的主权和电池储能(BES)装置的加入，以达到改善系统动力学行为的目的。
