Dimension of Distribution System Security Region
摘要
Abstract
The concept and calculation method of the dimension of distribution system security region(DSSR)are proposed. Firstly,the DSSR dimension is defined when the number of both constraints and variables are considered synthetically. Secondly,a DSSR dimension calculation method based on the main transformers connection vector is proposed.The key point in this method is to define a vector to describe the connection relationship among the main transformers and the DSSR dimension can be obtained without listing the security region expressions.Finally,an example is given to illustrate the proposed method.The relation between DSSR dimension and the distribution network is acquired by the preliminary analysis. The condition where the number of boundaries reaches the extreme value is also obtained.For different scale of distribution networks,the DSSR dimension is mainly affected by the number of transformers,feeders and sectionalizing switches.For the same scale of distribution networks,DSSR dimension may be different,and it is mainly affected by the connection modes of feeders.The concept of DSSR dimension proposed can rigorously describe the scale of DSSR and its corresponding N-1 security problems,which provides a necessary foundation for DSSR theory.关键词
