Introduction. Voltage sag, which is associated to a transitory drop in the root mean square voltage characterizing an electrical source network. During these perturbations, the corresponding electronic customers and devices will suffer from serious operating troubles causing dangerous damages. Purpose. In order to attenuate this disturbance effects, the Controlled Dynamic Voltage Restorer constitutes a very interesting solution among many others that have been proposed. The novelty of the proposed work consists in presenting an enhanced algorithm to control efficiently the dynamic voltage restorer when voltage sag is suddenly occurred. Methods. The proposed algorithm is based on an instantaneous phase locked loop using a multi variable filter to synthesize unitary signals involved in compensation voltages computation relative to the sag apparition. Practical value. A detailed study concerning typical voltage sag, which is consolidated by simulation and experimental results, is conducted to show the used algorithm’s effectiveness to cancel the corresponding voltage sag.

This work presents the design and simulation of a Dynamic Voltage Restorer (DVR) to mitigate power quality problems such as voltage sags and swells at sensitive loads to these types of disturbances, but with a compensation topology using one the most popular of the renewable energies, currently employed, which is photovoltaic solar energy. The DVR must operate with a control loop, monitoring the voltage at the load side and generating the voltage for compensation during the disturbances. The energy is obtained, from an array of solar panels for the injection of active power. The control algorithm discussed in this article is based on the Clark and Park transformations to generate the required signals for voltage compensation, these mathematical techniques allow fixing the variables and hence simplicity for the controller design. The results of the simulation in MATLAB/Simulink are used to show the performance of the proposed topology with symmetrical voltage sags in the distribution system.

This paper introduces a dynamic voltage restorer with independent three-phase structure, which is controlled on repetitive control strategy. Computer simulation of the whole repetitive control system is performed by Matlab/Simulink, and the results show that the effect of dynamic compensation can meet the request when voltage sags happened in electric power system.
