摘要:
      随着智能电网与能源互联网研究的兴起,分布式可再生能源和储能设备的不断接入,配电网的智能化发展已成为一种必然趋势。而大量现存的传统配电网如何适应自由、对等、灵活的目标,成为迫切需要解决的问题。文中提出基于电网的电气关联强度将传统配电网划分成若干具有强内部聚合特性的虚拟微电网,并提出了基于扩展信息、物理、社会经济(CPS)的虚拟微电网实施框架,以及边界划分、资源优化部署、协同能量管理的三阶段研究问题。针对第一个研究问题,通过定义电气关联强度,对复杂网络中经典的Newman快速分区算法进行改造,实现对虚拟微电网边界的自动优化。通过仿真算例验证了该方法的合理性和效率。
Abstract:
      With the fast development in the research of smart grid and Energy Internet, more and more distributed renewable energy and energy storage devices are connected into distribution networks, intelligent development of distribution network has become an inevitable trend. It is a big challenge for large-scale conventional distribution networks to be consistent with the requirements of free, equal and flexible interaction. Virtual microgrids with high internal convergence are proposed based on electrical coupling strength, which is partitioned from conventional power distribution networks. Furthermore, an implementation framework of virtual microgrids based on extended cyber, physical and socioeconomic is put forward, three-stage research problems of boundary division, resource optimization deployment and collaborative capability management are introduced. According to the first problem, by defining the electrical coupling strength, the classical Newman fast partitioning algorithm is upgraded in complicated network to realize the automatic optimization of boundary in virtual microgrids. Through case studies, the proposed algorithm is verified to be reasonable and efficient.
