摘要

电网是一个人工网络。研究分布式发电的复杂电网对人们的生活、生产和社会稳定具有重要意义。本文从动态角度研究了分布式发电并网时电网的同步可靠性和运行可靠性。研究发现，当分布式发电接入单一电网时，分布式发电输出功率越大，电网越容易同步，抗扰动能力越强。当分布式发电通过小程度负荷节点或大型子网接入互联电网时，将增强互联电网的同步能力。无论是单电网还是互联电网，接入电网的分布式发电越多，电网的同步能力就越好。

Influence of Distributed Generation Connection on Dynamic Characteristics of Power Grid

The power grid is an artificial network. Studying the complex power grid with distributed generation is of great significance to people's life, production and social stability. This paper studies synchronous and operational reliability of power grid when distributed generation enter the network from the dynamic point of view. It is found that the more the power output of distributed generation is, the more easy the power grid is to synchronize and the stronger the resistance to disturbance when distributed generation is connected to a single power grid. When distributed generation is connected to interconnected power grids through small degree load nodes or a large sub network, the synchronization capability of interconnected power grids will be enhanced. No matter single power grid or interconnected power grids, the more distributed generation connected to the grid there are, the more the synchronization ability of power grid will be improved.
