Abstract: This paper describes the solar wind hybrid power system for the generation of electricity over renewable vitalitymeans.The integrated power generation systems are resourceful in generation areas.Powerquality issues such as disturbances in voltage, current or frequency in sensitive industrial lotsoutcomes in letdown of end handlertackle.This papersignifies the techniques for the perfection of sag,swell and disruption in a supplyschemes with power groundedtackleDSTATCOM(Distribution Static compensator).As this device is most effective and efficient in injecting current and mitigating the sag,swell and reduction in interruption. The D-STATCOM uses 5 level multilevel inverter as Voltage source inverter,the switches are skilful by pulse-width-modulation technique (PWM). The DSTATCOM provides the reactive compensation for voltage stabilization in distribution systems,it also provides the protection over voltage sag which are caused due to reactive current demand. During the transient events the D-STATCOM provides the power factor correction,system stability and load balancing. The compensation characteristics and reliability, control schemes of the planned system is designed and carried out in MATLAB/SIMULINK.
