In this article, a new identification tool for dynamic voltage restorer (DVR) is proposed to achieve flexible active and reactive power dispatches during sags. The presented entirely relies on the theoretical analysis of elliptical transformation, marks are determined different injections by using one set digital codes. Besides, two parameters in accurate mathematical description current refere...

Recently, there was a great focus on integrating renewable energy sources (RESs) into electrical power systems (hybrid systems) due to their many environmental and economic advantages. The output of most these RESs is DC; some electronic devices, including inverters, must be used integrate the grid. Any maloperation, faults, or improper control in devices will enormously affect hybrid systems’ ...

This paper presents the application of dynamic voltage restorers (DVR) on power distribution Systems for mitigation of voltage sags/swells at critical loads. DVR is one of the compensating types of custom power devices. An adequate modeling and simulation of DVR, including controls in MATLAB, show the flexibility and easiness of the MATLAB environment in studying and Understanding such compensa...

With the prevalence of renewable energy sources such as wind power in system, analyzing fault characteristics systems composed DFIGs is becoming increasingly important. Therefore, this article analyzes, at first theoretically, a doubly fed induction generator (DFIG) during periods. It was found that current DFIG exhibited frequency offset phenomenon, which affected by depth voltage dips and can...

Power quality difficulties arise as a result of Renewable Energy Sources (RES) integrating with the grid. Voltage swell, sag, and harmonic distortion occur on grid due to power issues, which have an impact customers. An inexpensive series compensator, like Dynamic Restorer (DVR), is best solution for overcoming aforementioned problems. In this article, solar PV integrated DVR novel multilevel i...
