Abstract

Studies revealed that there is a continuous fluctuation of output power and voltage for a constant speed wind generator under random variations of wind speed. These irregularities in power output are affecting the power quality, reliability and sustainability of the distributed system. This paper reveals that fuzzy logic controlled DSTATCOM increase the available load voltage by enhancing the VAR compensation, thereby improving the overall power factor connected to dynamically fluctuating inductive load. The proposed control methodology is based on the “theory of Instantaneous power balance and direct voltage control” for the DSTATCOM. Simulations are carried out in MATLAB/SIMULINK environment.
