柔性生配电网:定义、组网形态与运行方式
Flexible Distribution Network: Definition, Morphology and Operation Mode
摘要
Abstract
The paper defines flexible distribution network (FDN) and proposes its typical morphology and operation mode.Firstly,the paper introduces FDN concept and flexible switching station (FSS) and key grid equipment of FDN.Then,FDN morphology is discussed and approaches to upgrade conventional distribution networks into FDNs are proposed.The paper also gives a specific FDN morphology based on present modes of typical overhead lines and cable distribution networks of single-and multi-connection.Next,discussion about FDN operation modes is performed in three conditions,i.e.normal operation,N-1 contingency and maintenance.A method on FDN N-1 security assessment is proposed.Finally,compared with traditional distribution networks,quantitative calculation and analyses on FDNs in normal and N-1 operations are carried out with case studies.It is verified that FDN morphology is more concise and flexible with better load balance,security and supply capacity.关键词
