Abstract
ABSTRACT The STATCOM (Static Synchronous Compensator) acts as a controllable source of reactive current to stabilize reactive power at system nodes and manage reactive flow in transmission lines. Typically modeled as a regulated voltage source, STATCOM enhances system stability and is a crucial component of FACTS (Flexible AC Transmission Systems). A novel robust control approach for STATCOM has been introduced to improve grid stability. This approach incorporates both speed and voltage control loops to reduce oscillations and is addressed as an optimization problem with robustness criteria for assessing the controllers effectiveness and stability. The Single Machine Infinite Bus (SMIB) system is used to explore dynamic stability and refine controller parameters. The proposed model, which utilizes PID controllers, employs a modified NSGAII genetic algorithm to determine Pareto optimal solutions. Simulations validate the model's capability to improve dynamic stability and reduce oscillations. Due to increasing loads and limited expansion of generation and transmission capacities, modern power systems face tighter operational constraints and more frequent low-frequency oscillations, which need to be quickly and effectively detected and managed. These oscillations influence system equilibrium and stability.
