Hybrid PV-Wind Energy System Connected to the Grid Using Dynamic Voltage Restorer Based on SMES and Battery for Mitigation of Voltage Sag

Abstract

Eco-friendly electricity can be provided by using renewable energy sources, which are abundant in nature and environmentally favourable. Due to their dependence on wind speed and solar irradiation, renewable energy sources such as wind and sunlight-based photovoltaics (PV) have a tendency to fluctuate in power production. If you want to safeguard and alleviate sensitive loads from fluctuations and deficiencies in the force conveyance side, it is usual practise to employ a dynamic voltage restorer (DVR). As part of this study, researchers are looking into the impacts of voltage change on a network by using a half-and-half PV/wind power architecture. Battery and super magnetic energy storage (SMES) DVRs are used to compensate for voltage dips. Three phases of magnitude and angle of voltage at PCC (Point of Common Coupling) are locked in a normal state and stored freely as part of the compensatory approach used. Power System Computer Aided Design (PSCAD/EMTDC) or Electro Magnetic Transient Design and Control (EMTDC) software is used to analyse and compensate for asymmetric and symmetrical voltage sags (EMTDC).
