【摘要】：清洁能源分布式发电技术以其优良的特性,是解决当前环境日益恶化问题与能源危机的最佳替代方式之一。伴随着以风能、太阳能发电和燃料电池为代表的清洁分布式发电技术日趋成熟和大量普及,更多的分布式电源将接入到配电网中。因此,对分布式发电接入配电网后给配电网带来的影响进行分析是非常有必要的。同时,对在配网中实施适合于分布式发电接入的配网管理的相关技术研究也应进行论证。首先,本文描述了分布式发电的相关定义和概念以及主动管理技术的概念和及其实施的意义。同时对分布式发电接入配网和实施配电网主动管理技术的国内外发展和研究现状进行了详细的阐述。其次,阐述了分布式发电与配网之间的关系。利用IEEE34节点系统,对单个分布式发电接入容量、接入位置、多个分布式发电接入容量和位置进行了介绍,分别对配网系统的潮流、电压分布和网损的影响进行了仿真实验和分析。然后,描述了主动管理技术关键技术概念,并针对分布式发电接入配网,提出了可应用的主动管理技术组成的架构、相关控制策略和手段。并以BaranWu33节点系统为例,对采用主动管理技术下配电网的仿真数据进行了分析。提出和分析了风电、光伏、燃料电池系统和小水电接入配电网的主动管理技术实施方案。最后,对本文所从事的工作进行了总结,并对今后研究工作的方向提出了展望。
[Abstract]:Clean energy distributed generation technology with its excellent characteristics, is one of the best alternative to the current environmental deterioration and energy crisis. Accompanied by wind, clean distributed generation technology of solar power generation and fuel cell as the representative of the mature and a lot of popularity, more access to the distributed power distribution network. Therefore, it is very necessary for DG to bring influence distribution network were analyzed. At the same time, the relevant technology of the implementation of network management for distributed generation access in network research should also be demonstrated. Firstly, this paper describes the concept and related concepts of distributed generation and active management technology and the significance of the implementation of research and development at home and abroad. At the same time of active management technology of distributed generation access network and implementation of distribution network Described in detail. Secondly, this paper describes the relationship between distributed generation and distribution network. By using the IEEE34 node system, access to a single distributed generation access capacity, location, a plurality of distributed generation access capacity and location are introduced, respectively, for distribution system trend, effects of electric pressure and the network loss and simulation experiments are carried out. Analysis. Then, describes the key technology of active management technology, and according to the distributed generation access network, the active management technology can be applied to the structure, control strategy and method. And the BaranWu33 bus system as an example, the active management of simulation data of distribution network technology are analyzed. Proposed and analyzed the wind power, photovoltaic, fuel cell systems and small hydro power distribution network active management technology implementation. Finally, engaged in the work of this paper are summarized, and on this The direction of the post research work is put forward.
