分布式发电技术及其对电力系统的影响

随着公平竞争的电力市场逐步建立,分布式发电将凭借其投资省、发电方式灵活、与环境兼容等优点拥有越来越大的市场份额。大量分布式发电系统接入电网,将对传统电力系统产生巨大的影响。首先介绍了分布式发电技术的基本概念以及其相对于集中发电方式的显著优点,并对现在比较热门的几种分布式发电技术做了介绍,然后分析了分布式发电对现有电力系统的影响,指出当大量分布式电源接入系统后,它对系统的影响不再局限于配电网,而将对整个电力系统的动态性能产生巨大的影响。

Distributed generation technology and its impact on power systems

Distributed generation(DG) will own more shares in the near future under fair competitive electricity market,because of the following advantages of saving investment,flexibility and environmental compatibility. The interconnection of DG will have great impact on traditional power systems. This paper puts forward the concepts of the distributed generation and its prominent advantages against the conventional centralized electric power system,introduces some kinds of distributed generation technologies,and analyzes the impacts of distributed generation on the existing power systems. It is pointed out that when the penetration level of distributed generation increases,the impacts of DG are no longer restricted to the distribution network but starts to influence the dynamic behavior of the power system as a whole.
