含高比例分布式电源的自洽型配电单元构建方法研究

Construction of Self-consistent Power Distribution unit with High Ratio Distributed generation

现有需求响应等相关技术方案并不能较好解决高比例分布式电源并网所造成的问题,还需要充分考虑负荷的特性,对基于源荷之间匹配特性的配电网组网的形态进行改进。为此,文章提出了基于分布式电源互补特性、多元化负荷互补特性和电源-负荷匹配特性的自洽型配电单元的概念,对自洽型配电单元的分类及构建的方法原则等开展了理论研究,仿真验证了自洽型配电单元的效果,为智能配电网规划提供借鉴。

With the development of demand response technology,the technical solution proposed only from the standpoint of distributed generation is not well adapted to the current form,and it is necessary to fully consider the characteristics of the load and improve the shape of the network.To this end,the concept of self-consistent distribution unit is proposed,and the definition of self-consistent distribution unit is elaborated,and the methods,principles and indexes of its classification and division are studied,and the final division is based on simulation.Finally,the development objectives and future research directions of related technologies are discussed and prospected to provide some thoughts and references for the development of smart distribution network planning theories and technologies under the new situation.
