The benchmark test system of distribution systems is a necessary benchmark and important tool for system analyzing researches and result data checking. In order to meet the development demand of the distribution systems which integrates with high penetration of distributed generations (DGs), a benchmark test system for the distribution systems is proposed which adapts to the current and future development trend. Based on the concentric zone theory and the typical regional settlement model in China, three typical distribution system scenarios corresponding to different system circle structure and regional development characteristic are designed in this paper. In order to adapt to the trend that the distribution systems will present the mixed state of AC and DC in the future, the typical improvement scheme of distribution systems in urban scenario is given. The benchmark test system of low-voltage distribution systems in rural scenario is also designed because of the high penetration of DGs. Moreover, the system structure, load parameters, integrated capacity and output characteristics of varies kinds of DGs in different scenarios are described in detail. Finally, the simulation results such as the time series power flow, reliability evaluation and hosting capacity of DGs are given. The benchmark test system proposed in this paper will lay a foundation for the future researches on distribution systems with high proportion of DGs and support the distribution systems planning, design, operation and dispatch effectively.
