Abstract

Its intermittent nature and comparatively elevated capital costs impede the contribution of abundant renewable energy sources globally compared to nonrenewable sources. Intermittency makes most of the renewable energy sources to be grid connected for reliability and power quality issues, which makes economically infeasible for remote areas energy supply where standalone micro grids more preferable. The advancement of power electronics technologies also makes to have sensitive loads, which are sensitive to power fluctuations. This paper intends the application of dynamic voltage restorer (DVR) which consists of different microsystem devices to improve the power quality of wind power system during voltage fluctuation conditions of sensitive loads. Symmetrical and asymmetrical fault scenarios are tested for improving the efficiency and the quality of the power supply and compliance with the IEEE nominal voltage standards. The results of sensitive load phase voltage value presented with and without the contribution of the DVR system. The wind power generation and operation of the DVR are done using Power System Computer Aided Design or Electro Magnetic Transient Design and Control (PSCAD/EMTDC) software. The presage compensation strategy is used for controlling of the DVR and its detailed mechanism is presented. The simulation results showed the proper applicability of DVR during any voltage sag/swell conditions.
