Performance Optimization of Hybrid AC-DC Power Systems with HVDC, SSSC, and STATCOM: Advanced Control and Optimization Strategies

Abstract

This study focuses on the AC-DC load flow challenge in hybrid power systems, incorporating Flexible AC Transmission System (FACTS) devices such as the Static Synchronous Series Compensator (SSSC) and Static Synchronous Compensator (STATCOM). To improve system performance, an innovative Hybrid Cuckoo-BAT-Gravitational Particle Swarm Optimization (HCB-GPSO) algorithm is developed for the optimal placement and operation of these devices. The methodology involves detailed mathematical modeling of AC-DC links, FACTS devices, and the formulation of an optimization problem targeting reduced power losses, improved voltage stability, and system reliability. Simulation results on IEEE test systems show the efficiency and reliability of the suggested method, showing significant improvements in voltage profiles, loss minimization, and overall system stability. The superior performance of HCB-GPSO compared to existing optimization techniques underscores its potential for addressing complex operational challenges in modern power systems.
