摘要
分布式电源(DG)接入电网后会对电网的电压分布产生很大影响。如何减少分布式电源并网后给配电网电压带来的影响,已经成为一个亟待解决的问题。使用IEEE33节点配电网络作为算例,应用Simulink软件搭建了仿真模型,通过改变分布式电源的容量以及接入位置来分析其对配电网电压分布的影响。在大量仿真算例与数据的基础上,并经过充分研究,总结出一套切实可行的将分布式电源并网的方案,以及并网应该遵循的一些准则,使配电网的安全性与经济性得到提高,对配电网中分布式电源的接入起到了很好的指导作用。
Voltage distribution will be effected significantly when distributed power （DG） is connected to a grid. How to reduce the impacts of the distributed power on distribution network voltage has become an urgent problem. By taking IEEE33-node distribution network as an example, a simulation model has been built based on SIMULINK software, with which the impacts on voltage distribution was analyzed when capacity and connected location of the distributed generation were changed. On the basis of a large number of simulation examples and data, a set of practical plans about integration of distributed generation with a grid and guidelines those should be complied with were summarized, by which the security and economy of the distribution networks with distributed generation can be improved.
