Three measures, namely, the adaptive barrier update strategy, the filter-line-search method and the feasibility restore phase, are simultaneously introduced in the conventional primal-dual interior point method (IPM) framework to enhance the robustness of existing optimal power flow algorithms when applied to systems with considerable number of flexible AC transmission system (FACTS) devices. First, an adaptive barrier parameter strategy is employed to update the barrier parameter after the current -barrier problem solved to certain accuracy. Second, a filter-line-search procedure is introduced to generate the next iterate. Third, the algorithm initiates a feasibility restore phase as a remedy in case of getting stuck at a non-optimal point. Comparative case studies with previous algorithms on both standard test systems and large-scale real-world systems demonstrate the novel algorithm outperforms conventional IPMs in robustness and efficiency.
