摘 要

分布式电源由于其能利用可再生能源的关系，可以解决我国经济发展中能源需求和环境保护之间的矛盾而不断发展。由于分布式电源的规模不断扩大，分布式发电的安装容量迅速增加，但是在高渗透率的情况下，分布式电源的利用率就会有所下降，因此有必要研究分布式电源高渗透对配电网的影响。本文围绕了分布式电源高渗透率的情况下集群的划分方法和控制方法进行了研究，并通过仿真验证了理论的正确性。

本文分析了在分布式电源高渗透率的情况下分布式电源的特性和配电网的特性。分析了分布式电源的出力特性和配电网的负荷特性。

建立了集群划分控制的方法及等值模型，提出了3种理论依据和3种可以实施的方法。介绍了集群控制的方法，研究了基于集群控制的优化调度方法即基于集群控制的优化控制方法。提出了基于集群控制的调控技术。

本文设计了33节点的仿真系统图，测试后完成了集群控制的作用效果，体现了集群的实施可靠性。

High penetration of distributed power distribution network and cluster partition control method

Abstract

Distributed power can continue to develop because it takes advantage of renewable energy which can solve the contradiction between economic development and environmental protection in energy demand. Due to the size of distributed power continues to expand, the installed capacity of distributed generation increased rapidly, but in the case of high permeability, the utilization of distributed power will decline, it is necessary to study the high penetration of distributed power distribution. This paper studied the method and the control method of dividing clusters in the case of high penetration of distributed power clusters were and use simulation to verify the correctness of the theory.

This paper analyzes the characteristic feature of distributed power and distribution network in the case of high penetration of distributed power . Analysied the output characteristics of distributed power and load characteristics of distribution network.

This paper established equivalent Model of cluster control division , proposed three kinds of theory and three kinds methods which can be implemented .It describes a method of cluster. control.It study optimal control method based on optimal dispatch and methods of cluster control of based cluster control. It proposed cluster control which based on the regulation.

This paper presents the simulation system 33 nodes, the test is completed the effect of cluster control, reflecting the implementation of the reliability of the cluster.

1. 引言

1.1分布式电源高渗透率配电网的研究背景

随着社会发展的需要，越来越多的不可再生能源被消耗运用到电力行业来维持社会的发展。化石燃料的使用严重污染了环境，并且利用率相对较低，这促进了可再生能源和可再生能源技术的开发与研究。可再生能源将会代替化石能源成为全球能源发展的趋势。以分布式发电的方式就地消纳是可再生能源的一种较为经济的利用模式，因此分布式电源并网的问题成为了可再生能源利用的最重要的问题。
