摘　　要：实时电价是电力市场中的重要概念。本文介绍了基于最优潮流(OPF)的实时电价模型以及原对偶内点算法的基本原理,并讨论了向心参数的取值对该算法收敛性的影响。通过对IEEE14节点系统的仿真分析,结果表明,有功实时电价比无功实时电价大的多;向心参数的取值对原对偶内点算法很重要,它的大小直接影响算法的收敛性和解的可行性。Spot Price is an important idea in the Electricity Market. Spot Price based on the model of optimal flow and the primal---dual interior point algorithm are presented in this paper. It is discussed that the value of central parameter effecting on the convergence of the primal-dual interior point algorithm. The numerical simulations and analysis on the IEEE14-bus system show that the value of active power Spot Price is much more than that of reactive power Spot Price and the central parameter cris very important at the Primal-dual Interior Point Algorithm,its value directly affect convergence of the algorithm and feasibility of the results.
