Representing a Novel control method for DVR Compensator in order to Use it in load's power quality

Having electricity with high quality is one of the more important aims in electrical systems. Disturbances in distribution systems can change voltage waveform. There are some methods to prepare high power quality for sensitive loads. In this research، we use “Dynamic Voltage Restorer” to compensate the harmful effects of disturbances on voltage. Since power systems sometimes have complicated dynamic behavior especially during faults; emotional self-tuning controller which is a powerful adaptive controller has been used. In order to improve the performance of this controller from point of view of power quality indices such as flash and sensitive load voltage THD، a new structure is proposed for this controller. Also by this controller، system has better performance during fault conditions. According to simulation results، this controller has better operation than both classical PI controller and emotional controller.
