Research on Virtual Microgrid Partition Method for Promoting Active Distribution Network Optimization Operation and Maintenance

  • 摘要: 随着分布式能源的大量接入,还有储能、电动汽车、柔性负荷等新技术的进步,主动配电网的运行控制越来越困难。针对这一问题,基于虚拟微电网的概念,提出了一种主动配电网微网化的分区优化划分方法,以虚拟微网分区的形式简化主动配电网的运行控制。该方法以通信成本最低、分区功率不平衡最小及分区供电独立性最高为目标,建立主动配电网微网虚拟分区优化模型。基于广度优先搜索算法获取各分区信息,提出主动配电网微网化虚拟分区方法,将主动配电网划分为多个虚拟微网分区。以改进IEEE-33节点系统为例进行验证。研究结果表明,所提方法可以提供面向主动配电网的虚拟微网分区建议,为主动配电网的高效运维提供支撑。

     

    Abstract: With the massive access of distributed energy, and the advancement of new technologies such as energy storage, electric vehicles, and flexible loads, the operational control of active distribution networks is becoming more and more difficult. Aiming at this problem, based on the concept of virtual microgrid, a micro-grid partition optimization method for active distribution network is proposed, which simplifies the operation control of the active distribution network in the form of virtual micro-network partition. The method establishes the virtual partition virtual optimization model of the active distribution network with aims of the lowest communication cost, the minimal partition power imbalance and the highest partition power supply independence. Based on the breadth-first search algorithm, each partition‘s information is obtained. The virtual micro-grid partitioning method of the active distribution network is proposed, and the active distribution network is divided into multiple virtual micro-network partitions. The IEEE-33 bus system is improved as an example for verification. The research results show that the proposed method can provide virtual micro-network partitioning suggestions for active distribution networks, and provide support for efficient operation and maintenance of active distribution networks.
