この論文は、韓国電力系統の公開データに基づく合成モデル「GIST 2064バス試験システム」を提示する。このモデルは、345kVおよび154kVの送電線網をOpenStreetMap/OpenInfraMapから再構成し、2064バス、512の発電・再生可能エネルギー源、3044の交流送電線などを含む。高需要時（85GW）の潮流計算で収束解が得られ、系統計画や脱炭素化研究に利用可能である。

English

This paper presents the GIST 2064-bus test system, a synthetic model of the Korean power grid built from public data. It reconstructs the 345kV and 154kV network from OpenStreetMap, includes 2064 buses, 512 generation sources, 3044 AC lines, and HVDC equivalents. The model solves to a converged operating point under 85GW demand, offering a platform for power flow analysis and decarbonization studies.

📄 Abstract（原文）

No model of the Korean transmission system at native resolution is publicly available, which makes reproducible research on one of the world's most distinctive grids difficult-an islanded interconnection with extreme separation between generation and the Seoul Metropolitan Area load center, low renewable penetration, and heavy reliance on extra-high-voltage (EHV) transmission. Working strictly from public data, and for research purposes only, we present the GIST 2064-bus test system, a geographically grounded synthetic model of the Korean grid. Unlike fully synthetic cases, whose lines match no real corridor, and aggregated public Korean models, it derives its 345 and 154 kV layout from the OpenStreetMap/OpenInfraMap power layer by a multi-source shortest-path reassembly of overhead-line geometry, gap-fills unreachable substations with a geographic minimum-spanning-tree backbone, and calibrates the aggregate circuit length to published national statistics (108/107/97% at 765/345/154 kV). The model spans 2064 buses, 512 generation and renewable sources (144 GW), 3044 AC line circuits plus high-voltage direct-current (HVDC) equivalents, 3073 transformers, and reactive resources (shunts and 11 FACTS devices), serialized to a PSS/E-compatible CSV schema. A general-purpose pandapower Newton-Raphson solver-with generator reactive limit enforcement, a secant-gain remote voltage-control loop, tap-changer and switched-shunt fixed-point control, and zero-impedance regularization-solves an 85 GW high demand snapshot to a single connected, converged operating point (mean voltage 0.996 pu, 2.3 % losses, no undervoltage buses), structurally consistent with the independent public KPG-193 model. The dataset, maps, and tooling are released as a citable platform for power flow, planning, and decarbonization studies.
