Abstract: This paper presents a combination of voltage source converter and capacitor banks which is called as Static Compensator (STATCOM), Voltage Source Converter (VSC) based diversion connected Flexible AC Transmission System (FACTS) devices which improves the dynamic and static voltage control in transmission in addition with distribution system. It is a reactive power return device which can produce and absorb the reactive power. The power quality has ongoing to play an important role in electronic and electrical industries. A system concerning the power quality measurement is voltage flicker and harmonics. Normally DSTATCOM is connected in distribution system. Optimizing the parameters of a bio-inspired algorithm’s naturally the main path to improve its performance. The distribution used in the displacement and creation of new solutions is also a factor to consider when enhancing its capacity. In this work, the efficiency of Gravitational Search Algorithm (GSA) and Cuckoo Search Algorithms (CSA) is investigated through MATLAB Simulink model. InThe IGBT is used as a power switch which has low switching loss and the turn off is very simple. In this paper THD is evaluated, disturbances obtained in the current waveforms are reduced by means of DSTATCOM. The distribution system with DSTATCOM and the control scheme used for power quality enhancement is simulated and validated.

Keywords: Static Compensator (STATCOM), Voltage Source Converter (VSC), Cuckoo Search Algorithms (CSA), Gravitational Search Algorithm (GSA).
