For studying the influence of the instalaltion position of battery energy storage system（BESS）and capacity of the energy storage system on subsynchronious oscillation（SSO）suppression result

in this paper

the supplementary damping control of battery energy storage with subsynchronous oscillation suppression function is used to certain double-fed wind farm in North China. The battery energy storage device system is installed at different positions of the wind farm and the PSCAD time-domain simulation analysis method is used to study the influence of the installation position of energy storage device on the sub-synchronous oscillation suppression result

so to determine the optimal installation position of the energy storage device system. The capacity of the battery storage system is changed at the optimal installation position so to study the influence of different energy storage capacity on the SSO suppression result

thus achieving the optimal configuration of the installation position and capacity of battery energy storage device system in the wind farm.
