Reactive Power Control to Assist Wind Penetration without Effect on System Operation

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 FACTS devices is carried out to solve the steady state problems of wind penetration using Genetic Algorithm (GA). Cases studied are carried out on modified IEEE39 bus system with wind penetration around 7% of system generation with change in reactive power injection to wind bus from the network. In all cases the system suffers from outage of one generator with load in one of system buses decrease by 15%. The system suffers from minimum voltage reduction, total loss increases and violation of power angle limits. Results prove that series FACTS devices in certain range are able to solve these problems associated with wind penetration in power systems.
