Abstract Based on singular value decomposition and predictor-corrector primal-dual interior point algorithm, a new strategy is proposed to optimizing reactive power of AC/DC power system. First, according to the coupled relationship of AC/DC network, the right singular vector index, which is obtained by singular value decomposition, is applied to identify weak bus as candidate nodes for installing new reactive compensation equipment; and then, a model of multi-objective reactive power optimization is established. The objectives consist of three important terms: network loss, application of reactive compensation equipment and voltage level. After the Jacobian and Hessian matrix of AC/DC system is extrapolated, the multi-objective model can be calculated with predictor-corrector primal-dual interior point method. Meanwhile, the optimized location and capability is obtained. At last, the simulation results show the validity and fast astringency of the strategy.
