This paper presents a modified instantaneous power control scheme of DSTATCOM for power factor
and harmonic compensation. The proposed control strategy has been introduced in order to enhance
some steadystate performances besides its functional elimination of power quality disturbances.
Power factor and harmonic current of a controlled feeder section are two vital roles in steadystate
power distribution system operation. Utilizing an already installed DSTATCOM to achieve these
additional control objectives can help system operators maximize overall system performances. In this
paper, a control scheme with constant power and sinusoidal current compensation is exploited. In order
to correct the power factor, a power factor control loop is required and therefore included in the control
block. To verify its use, a 22kV power distribution feeder with a threephase rectifier load was tested.
Results showed that integration of the proposed reactive power control loop can correct the power
factor of the controlled feeder to be unity power factor.
