Review of sub-synchronous interaction in wind integrated power systems: classification, challenges, and mitigation techniques

Abstract Emerging sub-synchronous interactions (SSI) in wind-integrated power systems have added intense attention after numerous incidents the US and China due to involvement of series compensated transmission lines electronics devices. SSI phenomenon occurs when two system elements exchange energy below synchronous frequency. related wind plants is one most significant challenges maintaining stability, while practical farms, which has been observed recently, not yet described on source conventional literature. This paper first explains traditional development its classification as given by IEEE, then it proposes a according current research status, reviews several mitigation techniques challenges, discusses analysis for SSI. The also describes effect active damping controllers, control scheme parameters, degree compensation, various used (WPPs). In particular, supplementary controller with converter controllers Doubly Fed Induction Generator based WPPs briefly pronounced. provides realistic viewpoint potential outlook readers properly deal techniques, can help engineers planning, economical operation, future expansion sustainable development.
