This paper presents a modified instantaneous power control of D-STATCOM for enhancement of steady state performances of the system. Power factor and harmonic content of a controlled feeder section are two vital roles in steady-state power distribution system operation. The conventional power control in single-phase or three-phase circuits has been defined on the basis of the average value concept for sinusoidal voltage and current waveforms in steady states. The instantaneous power is defined on the basis of the instantaneous value concept for arbitrary voltage and current waveforms, including transient states. The proposed control strategy has been introduced in order to enhance some steady state performances. Utilizing an already installed D-STATCOM to achieve these additional objectives can maximize the 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. The system is evaluated with MATLAB/SIMULINK software
