        abstract = {Renewable energy sources like solar photovoltaic (PV) and wind power systems play a crucial role in modern electricity generation. However, their reliance on current and forecasted weather conditions leads to inconsistent energy production and output variations. This variability places increased demands on energy transmission and distribution systems to quickly compensate and maintain stability. This paper introduces a new smart grid application for power system operation, utilizing a Static Compensator (STATCOM) device to enhance power quality, improve power flow in the distribution system, reduce unwanted harmonics, and compensate for reactive power in power sources.
A quasi-Z-Source Inverter (qZSI)-based STATCOM is integrated with a Three-Phase Four-Wire (3P4W) distribution system. The proposed compensator circuit combines a qZSI and a PV system, which facilitates switching. To control the compensator, an Adaptive Frequency Fixed (AFF) Second Order Generalized Integrator (SOGI) is implemented. While the Fuzzy Logic Controller (FLC) has traditionally been used to optimize Proportional Integral (PI) controller parameters such as Kp and Ki, this paper introduces the use of an Teache learner-based optimization (TLBO) for optimization. Experimental results demonstrate that the TLBO outperforms FLC by achieving superior dynamic performance and accuracy. Specifically, the TLBO-optimized system effectively reduces Total Harmonic Distortion (THD) of the source current from 25.5% to 1.1%, compared to 1.3% achieved with FLC. Additionally, the system efficiently supplies active power to the load, showcasing TLBO's superior control and adaptability in modern smart grid applications.},
