HPDS133-bus: A Benchmark Test System for Distribution Systems with High Penetration of Distributed Generation

The benchmark test system for distribution systems is necessary and important for system analysis and result data checking. In order to meet the development demand of the distribution systems which integrate with a high penetration of distributed generation (DG), a benchmark test system for the distribution systems which adapts to current and future development trends is proposed. Based on the concentric zone theory and the typical regional settlement model in China, three typical distribution system scenarios corresponding to different system circle structures and regional development characteristics 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, a typical improvement scheme of distribution systems in urban scenario is presented. The benchmark test system of low-voltage distribution systems in a rural scenario is also designed because of the high penetration of DG. Moreover, the system structure, load parameters, integrated capacity and output characteristics of varies types of DG 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 future research on distribution systems with a high proportion of DG and effectively support the distribution systems planning, design, operations and dispatches.
