The China urban power grid is evolving to smart distribution grid, of which the operating circumstance will be more complicated. Security region is a new method for the distribution system operating. This paper studies the smart distribution system security region (DSSR) from the view of user load, taking two main elements into account, which are distributed generation (DG) and demand response (DR). Firstly, it analyzes and formulates the characteristics of security operating for distribution systems with DG and DR then the DSSR with DG and DR is modeled. It observes the DSSR 2D sections on case grids and studies the mechanism of DG and DR on DSSR, based on which the guidance for the distribution system planning and operating is proposed. The DSSR in this paper is consistent with the usual practice of dispatchers and could be a useful tool of the security monitoring and analysis for urban power grids, in which the user load service is more important than the service of DG and DR.
