What is KPG 193 BPESD-11?

KPG 193 BPESD-11 extends the KPG 193 test system with Korean transmission grid scenarios from 2022 to 2038 based on Korea's 11th Basic Plan for Long-Term Electricity Supply and Demand (BPESD-11, 11차 전력수급기본계획). It provides yearly MATPOWER-compatible network snapshots, hourly time-series profiles, renewable capacity data, and expansion metadata.

The dataset reflects planned generation and transmission changes under Korea's 11th Basic Plan for Long-Term

Network evolution of the KPG 193 BPESD-11 test system from 2022 to 2038.

Electricity Supply and Demand (BPESD-11). Across the planning horizon, it includes 61 generator additions, 49 generator retirement records, 207 AC branch additions, and 7 DC line additions.

This dataset is part of the KPG Test System module within the KPG (Korean Power Grid) Platform. It remains compatible with KPG Run for power flow and unit commitment simulations and KPG View for map‑based network and result visualization.
