Abstract
The Distributed Static Compensator (DSTATCOM) is a compensator that regulates the flow of reactive power in distribution systems/networks by providing quick control of reactive as well as active powers. This work introduces the modeling and implementation of a 3-phase DSTATCOM using a Weighted Chimp (WdCH) optimization algorithm for Power Quality (PQ) improvement. The DSTATCOM is critical in improving the distribution network’s PQ with balanced and unbalanced loads. Also, there is a quick deviation in the DC link voltage coupled with the compensating device during the load disturbance in the systems. The proposed control algorithm optimizes the fundamental weight values of load currents for determining the reference grid currents’ magnitude and phase values, as a result, provides gating pulses for a 3-phase Voltage Source Converter via SPWM. The efficacy of the proposed control approach is analyzed concerning the convergence of the weighted values and the minimization of the Total Harmonic Distortion (THD) value.
