Optimal location of series FACTS to improve the performance of power system with wind penetration

Wind generation connection to power system affects steady state and transient stability. Furthermore, this effect increases with the increase of wind penetration in generation capacity. In this paper, optimal location of series FACTS devices is carried out to solve the steady state problems of wind penetration. Two case studies are carried out on the modified IEEE39 bus system, one with wind reduction to 20% and the second with wind penetration increase by 50% in the two cases system suffers from outage of one generator with load in one of system buses decreased by 15%. The system suffers from minimum voltage reduction, total loss increase and violation of power and power angle limits. This paper found that series FACTS devices in certain range are able to solve these problems associated with wind penetration in power systems.
