Investigation on Voltage Stability in a Distributed Generation Power Grid Influenced by PMSG and DFIG Based Wind Energy Conversion System

Abstract

– Countries have pledged to meeting the demand for electricity while also generating electricity from renewable sources in order to slow environmental degradation. Compared to other forms of alternative energy, wind power has a comparatively small environmental impact despite its size. Instability on the grid is a common consequence of adding wind power. Voltage instability is a common type of stability issue. The wind is an unpredictable element of nature. Wind velocity shifts as a result of varying turbine rotation speeds. For back-to-back converters to effectively maintain a stable grid voltage, the DC link voltage and the grid voltage must be the same. In this study, we’ll look about how the DFIG and PMSG affect voltage stability. In this study, we test the voltage stability of WECS built on PMSG and DFIG in three distinct scenarios. The whole system is created and analyzed with the help of Matlab/Simulink. The results of this inquiry have far-reaching consequences. This research provides important insight into how renewable energy sources may be better integrated into the grid, which could radically alter the energy industry.
