| 摘要: |
| 结合电力系统的特性，提出了一种基于稀疏技术的原－对偶内点法求解最优潮流问题，它在处理等式约束和变量型不等式约束时，能够同时处理函数型不等式约束，并且没有新的注入元注入系统。提出了一种新的迭代步长和中心方向的修改策略，同经典的牛顿法最优潮流比较表明，不需要预估有效约束集和进行试验迭代，易于编程实现。 |

| Abstract: |
| Regarding to the properties of power system and based on sparse method,a primal dual interior point method is presented to solve the optimal power flow problems.Together with the restraints of equations and variable inequations.the restraints of function inequations can be treated without new put in element to be generated.A new revision strategy for iteration step and centering direction is proposed in this method.Compared with the classical Newton OPF method,it does not need the binding sets and trial iterations,making the implementation of programming easier. |
| Key words: optimal power flow,primal dual interior point method,Newton method,duality gap,centering direction |
