This paper proposes an application of the bee algorithm (BA) in order to design an optimal proportional-integral-derivative (PID) controller, a sliding mode (SM) controller, and a fuzzy sliding mode (FSM) controller for a dynamic voltage restorer (DVR) system. The DVR is an electronic device, which has excellent dynamic capabilities and is well-suited in protecting critical or sensitive loads from short duration voltage sags or swells. The parameters of the optimal PID, SM, and FSM controllers are automatically tuned by the BA to compensate for the magnitude of load voltage by injecting the compensating voltages when the source voltage sags and swells. In order to confirm these concepts and to show that the proposed strategy outperforms other strategies when it is compared to others using the trial and error method, experimental and simulation setups were implemented in various cases.

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 presents the modelling and simulation of Dynamic Voltage Restorer (DVR) for mitigation of voltage sags and swells which are the major problems and issues on non linear loads.The Dynamic Voltage Restore (DVR) has become popular as a cost effective solutions for the protection of sensitive loads from voltage sags and swells.. The control of compensation voltages in DVR based on a-b-c to d-q-0 algorithm is discussed. The proposed control technique is cost effective and simple to design. Computer simulations are carried out in a suitable test system to investigate the effectiveness of control technique by using MATLAB/SIMULINK software.
