Sub-synchronous resonance in wind energy integrated grid – problem and mitigation techniques – a review

<p>When wind energy conversion systems (WECS) are integrated with the Grid system then there power quality issues arises. The fluctuation in delivery to grid demands robust control for a better quality. Therefore, voltage and frequency stability due integration of is primary concern improve overall capability WECS. This paper reviews introduction WECS introduces dynamic that include sub-synchronous resonance (SSR), low ride through (LVRT), support from generation, synchronization, transients. Also, it focusses on sub synchronous introduced doubly-fed induction generator (DFIG) turbines transmission lines capacitive seriescompensation. review various methods used by researcher’s mitigations discussed detailed further research perspective.</p>
