Abstract Full-dimensional direct observation of distribution system security region (DSSR) is carried out in this paper. Firstly, the existing observation methods are summarized. Secondly, a full-dimensional direct observation method of DSSR is proposed. The full-dimensional direct observation of two-supply-one-standby and flexible two-supply-one-standby connections shows that the security domain of two-supply-one-standby is a concave polyhedron, which is composed of a“domain core” and multiple“domain corners”; The surface of its security region has “ridges” and “valleys”, and “valleys” form domain depression. The security domain of flxible two-supply-one-backup wiring is a convex polyhedron, and there is no “valley”, which fills the traditional depression of two supplies and one backup It can be seen that the full-dimensional direct observation clearly shows the different geometric characteristics of different power grid structures embodied in the security region. This paper further gives the physical meanings and formation reasons of “region core”,“region angle”,“ridge” and“valley”. Finally, the method of this paper is compared and summarized with other security domain observation methods.

Key words： Distribution system security region full-dimensional direct observation region core region angle ridge valley
