一种综合考虑全网和局部的网损优化方法

摘要

With the continuous development of power grid construction in our country, the operational node is increasing, lead to the amount of data for the calculation and analysis in power system have greatly increased. While ensuring the safe operation of power system, more and more requirements for economic running is also put forward. The traditional loss calculation and analysis methods of electric network cannot meet the requirements of the current development of grid. At first, the current problems existing in the electric network loss optimization method are discussed, the optimal power flow calculation method is put forward for the network loss of global optimization. Secondly, the analysis thoughts of the local optimization and quadratic optimization of global network loss are also proposed. Finally combining visualization technology, the optimization analysis software of visualization network loss is designed and compiled on the basis of the theory and method. The feasibility and effectiveness of this method are verified by the practical application of power grid.%随着我国电网建设规模的不断扩大，运行节点日益增多，导致电力系统计算分析的数据量剧增。电力系统在保证安全运行的同时，对其运行的经济性也提出了越来越高要求，传统的电网网损计算分析方法已经不能满足电网当前的发展需要。首先探讨了当前电网网损优化方法中存在的问题，提出利用最优潮流计算方法先进行网损全局优化，其次进行局部优化分析，再进行全局网损的二次优化分析思路。最后在理论方法的基础上结合可视化技术，设计并编制了可视化网损优化分析软件，并通过电网的实际应用验证了该方法的可行性和有效性。
