Power Quality Enhancement in STATCOM connected Distribution Systems based on Gravitational Search Algorithm

The power quality (PQ) issue is get new measurement because of power system rebuilding and moving pattern towards distributed generation. PQ comprises of an expansive number of unsettling influences, for example, voltage sags, swells, harmonics, notch, flicker and so forth. To conquer these issues identified with the PQ, FACTS gadgets are presented. A distribution static compensator (D-STATCOM) is one of the FACTS gadgets makes it productive answers for enhancing the PQ in distribution system. So as to diminish the PQ issues, the D-STATCOM exhibitions are enhanced. In this paper, a Gravitational search algorithm (GSA) is proposed for enhancing the execution of D-STATCOM and remunerating the PQ. The algorithm is a recent improvement in the territory of nature enlivened calculations for worldwide streamlining. The proposed strategy is utilized for extricating the reference current for repaying the D-STATCOM and controlling the dc link voltage. The proposed technique based D-STATCOM is utilized for reducing the harmonic disturbances. In addition, the load balancing and reactive power compensation is accomplished. The proposed technique is executed in MATLAB/Simulink platform and its execution is assessed. The execution of the proposed technique is contrasted and the FLC controller and ANN controller.
