摘　　要：高压直流输电在远距离大容量输电、海底电缆输电等方面具有独特的优势,但直流设备的引入也使得交流系统最优潮流算法无法直接应用于现存的交直流系统,为此,先基于传统最优潮流算法,结合直流系统的稳态模型,提出一种含高压直流输电的预测-校正内点法最优潮流。多个算例仿真表明,该算法在不同的控制方式下均具有较好的适应性和收敛性,且迭代次数少于原对偶内点法,可减少计算量,节省计算时间。High voltage direct transmission has special advantage in remote and high capacity transmission and submarine ca- ble transmission, but introduction of direct equipments makes it impossible to apply AC power system optimal power flow al- gorithm in existing AC-DC power system. Therefore, this paper presents predictor-corrector interior point method with high voltage direct transmission based on conventional optimal power flow algorithm and combining steady- state model of DC system. Multiple algorithm simulations show that this algorithm is provided with good adaptability and astringency under dif- ferent control ways and its iterations are less than that of prime-dual interior point method which may reduce calculated a- mounts and save calculated time.
