Modeling and Simulation of Unified Power Quality Conditioner (UPQC) for Power Quality Improvement in Smart Grids

International Journal of Latest Technology in Engineering Management & Applied Science
Abstract—In modern smart grids, maintaining high power quality is essential for ensuring efficient, reliable, and stable operation of electrical systems. The proliferation of nonlinear and sensitive loads has increased issues such as voltage sag, swell, harmonics, and reactive power imbalance, which adversely affect overall power performance.
