#### Abstract

In this paper a single step calculation of Non-Iterative Optimization Algorithm for Distributed Static Compensator (D-STATCOM) is designed for the enhancement of power quality. Power Quality issues such as voltage sag, voltage swell and harmonics are being solved in this paper. By the estimation of the conductance factors and using the power demand to be constant and the limits for the harmonics as constraints in the algorithm is developed. The main objective of the proposed algorithm is to optimally determine the conductance factor to maximize the supply-side power factor based on conditions to predefined source current total harmonic distortion (THD) limits as inequality constraint and average power balance as equality constraint. The proposed algorithm optimally determines the conductance factors to maximize the supply-side power factor based on average power balance as equality constraint to compensate for voltage sag and swell. A single step calculation using conductance factor is done to obtain the reference using the proposed algorithm. The reference current generated by using the Non-Iterative Optimization Algorithm is used to control the voltage source converter of D-STATCOM for power quality enhancement. *Copyright © 2013 Praise Worthy Prize - All rights reserved.*
