Enhancing Power Quality in Single-Phase Systems Using Photovoltaic and Hybrid Energy Storage with Adaptive Control

The crucial component of power systems is Total Harmonic Distortion (THD), which needs to be maintained at the lowest feasible level as per the regulation. In power systems, lower THD is correlated with higher efficiency, lower peak currents, and high-power factor. To improve power quality in single-phase systems, photovoltaic and battery energy storage under dynamic loads is managed using modern adaptive control techniques. The research focuses on the creation of smart grid control algorithms that can handle changing energy sources like photovoltaic (PV), two-way power flow, and increase power quality, as well as demand forecast models to maximize hybrid energy storage utilization and improve grid management. Under different load scenarios, the model efficiently minimizes harmonic distortions, reduces voltage fluctuations, and improves grid stability. The findings point to a stable model with a constant power supply and THD of less than 1%. The results show single-phase system power quality can be improved and distributed energy resource performance can be maximized by implementing adaptive control systems. By doing so, the reliability of the electrical supply can be increased, and photovoltaic and hybrid energy storage can be better integrated.
