Description: 无功优化IEEE论文With the increased loading of existing power system, the problem of voltage stability
and voltage collapse has become a major concern in power system planning and operation. The
dependence of the system voltage profile on reactive power distribution forms the basis for reactive
power optimisation. The technique attempts to utilises fully the reactive power sources in the
system to improve the voltage profile and also to meet the reactive power requirements at the
AC–DC terminals to facilitate the smooth operation of DC links. The method involves successive
solution of steady-state power flows and optimisation of reactive power control variables with
unified power flow controllers using linear programming technique. The proposed method has-With the increased loading of existing power system, the problem of voltage stability

Description: 优秀论文配套源码。分布式电源的接入使得配电系统从放射状无源网络变为分布有中小型电源的有源网络。带来了使单向流动的电流方向具有了不确定性等等问题,使得配电系统的控制和管理变得更加复杂。但同时,分布式电源又具有提高电网可靠性,绿色节能,等等优点,所以为更好的利用分布式电源为人类造福,我们必须对其进行研究与分析。
本文采取通过利用仿真软件Matlab编写计算潮流程序模拟分布式电源接入配电网的模型进行潮流计算的方法对分布式电源的稳态影响进行探索与分析。
选取了34节点的配电网网络模型,通过对单个以及多个分布式电源的接入位置以及容量的不同情况对34节点配电网的网损以及节点电压状况进行了分析。
-The distributed generation access to distribution system makes passive radial distribution network to active medium-sized power distribution network. It brings uncertainty to one-way direction power flow, etc., and it makes the control and management of the distribution system more complicated. Otherwise, it can bring a lot of benefits, such as more reliable, and it is green power. The distributed generation should be better known , so we can benefits more.
So the program called Matlab was used to compile a program to solve the power flow problem. By this program, we can text which factor can influence the distributed generation’s access to the distribution system.
The IEEE 34 Node model was chosen to be discussed how different factors can influence the power quality. This article analyzes distributed generation’s influence to the distribution system of energy lost and voltage level.
