Online comprehensive optimization method for network loss of power system based on network topology adjustment

一套电力系统能否实现运转的经济性,需要通过其产生的网络损耗来加以衡量。提升电力网络对自身损耗的控制能力,可以使工作状态下的电力系统更好地节省传输消耗。本文中以在线网络拓扑结构调整理念为基础提出创新性的、综合性电力系统网络损耗控制措施,同时保证电力系统的各项指标地安全阈值都能得到满足。线性或非线性理念综合应用得到的三阶段策略是所研究优化策略的主要方式,也是一种让计算性能和控制稳定性更加优越,同时可应用于即时优化的方式。

The network loss of the power system is an important indicator reflecting the economics of the power system.The reduction of network loss(optimization)is of great practical significance for improving the power transmission efficiency and saving energy of the power system.In this paper,a novel online optimization method for power system network loss based on network topology adjustment is proposed.This method can quickly solve the network loss optimization scheme in online scene,and the solution can meet the operational power system.The online optimization strategy of network loss proposed in this paper is a three-stage strategy combining linear method and nonlinear method.It improves the calculation speed and reduces the adjustment number of control variables,which is more conducive to the online network loss optimization of power system.
