高比例分布式电源接入配电网的实验平台构建

Construction of experimental platform for high proportion distributed power supply connecting to distribution network

针对分布式电源大规模接入到配电网中对配电网造成广泛的影响及传统实验教学的不足等问题,构建了综合性、开放性的主动配电网实验平台,主要包括交流微网系统、直流微网动模系统、配网动模系统和能量管理系统。介绍了实验平台建设的背景、构建方案及实验平台用途。该平台为研究分布式电源接入配电网产生的稳定性及能源优化系列问题提供了实验研究支撑,改善了实验条件,促进了实验教学的改革,可满足本科生和研究生实验探究、课题研究及课程设计等多层次的需求。

Aiming at the problems such as the wide effect caused by the large-scale connection of the distributed power supply to the distribution network on the network, the shortcoming of the traditional experimental teaching, etc., an experimental platform for a comprehensive and open active distribution network is established, which mainly includes the AC micro grid system, the dynamic simulation system of DC micro grid, the dynamic simulation system of distribution network and the energy management system. The background, the scheme and the utilization of the experimental platform construction are introduced. This platform provides the experimental support {or the study of the issues about the stability caused by the connection of the distributed power supply to the distribution network, about the energy resourse optimization, etc. , which improves the experimental condition, promotes the reform of experimental teaching and meets the multi-level needs of undergraduate and graduate students for experimental research, project research, curriculum design, etc.
