PROJECT TITLE :

A Study on The Impact of Wind Farm Spatial Distribution on Power System Sub-Synchronous Oscillations

ABSTRACT:

Motivated by many recent incidents, this paper investigates the impact of wind farm spatial distribution and shunt compensation levels on triggering system-facet sub-synchronous oscillations (SSO) in wind-integrated power systems. Quantitative analysis on system eigenvalue sensitivities with respect to wind farm and transmission line parameters plus system operating conditions is performed systematically to understand the multi-wind-farm-induced SSO. Coupling relationship for wind turbines with identical and totally different parameter settings on the studied SSO modes is investigated. Electro-magnetic simulations are performed on a multi-machine wind farm model derived from a practical wind-integrated power system, so as to verify the proposed study.
