Transmission expansion planning of systems with increasing wind power integration

Abstract—This paper proposes an efficient approach for proba-bilistic transmission expansion planning (TEP) that considers load andwind power generation uncertainties. The Benders decomposi-tion algorithm in conjunction with Monte Carlo simulation is used to tackle the proposed probabilistic TEP. An upper bound on total load shedding is introduced in order to obtain network solutions that have an acceptable probability of load curtailment. The pro-posed approach is applied on Garver six-bus test system and on IEEE 24-bus reliability test system. The effect of contingency anal-ysis, load and mainly wind production uncertainties on network expansion configurations and costs is investigated. It is shown that the method presented can be used effectively to study the effect of increasing wind power integration on TEP of systems with high wind generation uncertainties.
