Analysis of transient stability in power systems with multiple shunt and series compensators

This study investigates the effect of multiple shunt and series compensators in transient stability case of a multi-machines power system. 22 bus multi machine real systems are modeled with static synchronous compensator (statcom) and static synchronous series compensator (sssc). the locations of the compensators are identified depending on the weak buses and transmission lines with highest voltage dip during transient cases. transient stability cases are examined without statcom and sssc, with statcom and sssc multiple statcom and sssc. besides, angular speeds of synchronous generators and variations voltage of buses are examined. oscillations can decrease within short time with multiple statcom and sssc in transient instability case.
