摘要
提出了一种以综合目标为优化方向的最优潮流算法,对电力市场环境下的发电成本、输电成本及无功服务成本进行了综合建模,获得电力市场环境下更好的电网潮流优化效果;算法还考虑了静态安全约束,使用线性化建模技术构建约束方程,最终使用内点法求解;对测试电网模型的仿真结果说明了方法的有效性与实用性。
An optimal power flow algorithm based on integrated objective was proposed, which maked a comprehensive modeling based on the generation cost, transmission cost and reactive service cost of electric power market, and better power grid flow optimization effect in electric power market environment was gotten. Moreover,the algorithm was taken into account the static security constraints,and the linearized modeling technique was used to construct the constraint equation. Finally the interior point method was used. The simulation results of the test grid model showed the effectiveness and practicability of the method.
