N2 - In the distribution network, a distribution static compensator (DSTATCOM) is used to address issues such as reactive power control, harmonic suppression, and the balancing of grid-side current. This paper presents a cascaded enhanced second-order general integrator with a prefilter (CESOGI-WPF) control technique for DSTATCOM. In addition to the prevention of non-sinusoidal load currents, the proposed control approach allows for the extraction of the positive sequence and fundamental components from distorted grid voltages. Various loading scenarios, steady-state conditions, and dynamic conditions are examined to assess the performance of the proposed controller. Based on the results of this work, the existing controllers were compared with respect to their Total Harmonic Distortion (THD), steadystate error, and computational complexity. A prototype of the proposed control scheme has been validated experimentally in a laboratory setting. It has been observed that the % THD of the grid current is maintained according to IEEE-519 harmonic standard and that the grid-Tied DSTATCOM is reliable under all load conditions.
