Design and Performance Analysis of WSCC System Using Modified Grey Wolf Optimization for Optimal Power Quality Enhancement.

At present, the usage of various energy sources in the electricity grid has formed new challenges like power quality effectiveness, energy utilization, and voltage stabilization. With the recognition of smart grid, the maintenance of power quality (PQ) has been regarded as the challenging one. Primarily, APF are employed in an attempt to recompense the issues associated with power quality, as they can filter out promptly and responds vibrantly. Here, in this work, an IEEE 9 Bus System based on WSCC is introduced along with UPQC combined DPFC system. To accommodate a renewable energy source, one of the generators test system. MGWO approach-based PID device is combined with DC Source as a converter for 3-phase inverter. This arrangement is studied using Simulation in both cases with and without DPFC. In addition, the performance estimation is done in terms of parameters like load voltage and current, shunt voltage and series current, and grid current along with their THD values. Based on the outcome, it is found that the proposed UPQC–DPFC combination helps in effective harmonic elimination and increased power storage at the output side. [ABSTRACT FROM AUTHOR]
