The reliability and operational test system of a power grid with large-scale renewable integration

This paper proposes a reliability and operational test system named XJTU-ROTS2017, characterized by large-scale renewable power integration and long-distance transmission. The test system has 38 nodes, 63 lines, 15 transformers and 20 generators in three areas, with peak load 10,421 MW and total installed capacity 16050 MW. Electricity primarily transmits from a resource-rich area to a load area, carrying wind/solar power generation. The determination of component parameters and grid topology is based on design manuals and typical practices. The test system can be conveniently applied to reliability evaluation and operation optimization of composite power systems integrating coal/hydro/solar/wind resources. Finally, the extended applications to AC/DC hybrid power systems and interconnected power systems are discussed.
