This paper elaborates a hybrid synchronous reference frame method has been proposed for the distribution static compensator (DSTATCOM) to enhance the compensation performance. This controller is designed in such a way that it generate the reference with respect to the change in load to reject the harmonics. Furthermore, a hysteresis controller is employed for switching pattern generation. Fuzzy logic controller is also implemented in MATLAB/simulink environment here to analyze the total harmonic distortion. Experimental analysis of the DSTATCOM demonstrates the potency and reliability of proposed controller over existing control strategy in the from of total harmonic distortion.

In this manuscript, a new control approach is counselled for DSTATCOM to resolve power quality (PQ) related issues. The Non-dual Adaptive Controller (NDAC) is employed with DSTATCOM to enhance the performance in terms of stability. The DSTATCOM is the constituent of voltage source inverter shunt DC-capacitor. A hysteresis block is employed for switching pulse triggering. The counselled scheme is a new method of shunt compensation and offers superior performance, for the lower frequency band in comparision with traditional strategies. Now-a-days we are dealing with huge nonlinear loads which draws non sinusoidal currents and also they generate large amount of harmonics. There are various advantages of using this new modified adaptive controllers over the tradition controllers. We are going to compare the performance of this new counselled controllers performance with the existing one in this literature. This new controller is initially simulated over MATLAB 2016 and then the efficacy of the counselled control approach (NDAC) is investigated using Laboratory prototype. Hardware setup is then authenticated through prototype with the help of dSPACE 1104. The execution reflects wide variation in the performances of both the controllers and also shows the supremacy of Non-dual adaptive controllers in terms of various aspects like harmonic current reduction, reduction in Total harmonic distortions during load dynamics.
