Hybrid fuzzy PID control with HAEFA optimization for simultaneous voltage and frequency stabilization in multi-area diverse source power systems

This paper addresses the stabilization of voltage and frequency in multi-area diverse source power systems (MADSPS). Consequently, to attain this, an investigation was carried out on the load frequency control and automatic voltage regulation in combined (CLFC-AVR) analysis. The MADSPS comprises multiple generation units, such as Thermal-Hydro-Wind in each area, and performs the analysis by laying area-1 with a 10% step load disturbance (10%SLD) under the supervision of a fuzzy-aided proportional-integral-derivative (PID) optimally rendered with a novel searching strategy of hybrid (H) artificial electric field (HAEFA) algorithm. However, the tuning of the fuzzy PID controller using the HAEFA technique is performed under different time-domain objective functions and their combinations to reveal the most suitable index for optimization of the considered model. Moreover, the efficacy of the HAEFA-tuned fuzzy PID was compared with classical PI/PID. Further, the CLFC-AVR investigation on MADSPS is stretched with the integration of superconducting magnetic energy storage (SMES) in each area and the flexible AC transmission device of the thyristor-controlled series compensator (TCSC) with a tie line for performance boost.
