含分布式电源的配电网重构

Reconfiguration of Distribution Network with Distributed Generation

为了使分布式电源接入配电网效益达到最大化,提出含分布式电源的配电网重构。针对常用的含分布式电源的配电网结构原型,提出了一种基于邻接矩阵和粒子群优化的混合算法。根据含分布式电源配电网的结构特点,建立了含分布式电源配电网的数学模型,并以负荷损失最小为主要目标函数。运用Matlab对算法进行编程,将该算法运用到此配电网模型中,对算例仿真结果进行分析,表明该算法不依赖网络的原始结构,并且具有迭代次数少、求解快速、简单有效的特点,避免了复杂的数学运算,具有很好的实用性。

As to maximize the benefit of the distribution network with Distributed Generation, the reconfiguration of distribution net- work with distributed generation is referred to. This paper puts forward an algorithm combining the adjacency matrix and the particle swarm optimization according to the common distribution network pro-type. According to the characteristic of the distribution network with distributed generation, it builds the mathematic model of the network, which aims at a minimum load loss. Program this algo- rithm on Matlab and apply this algorithm to the case, then the results show that it has a characteristic of not depending on initial struc- ture of the network, working rapidly and efficiently by avoiding the complex calculation. It proves a better practical use.
