PyPSA-Korea: An open-source energy system model for planning Korea's sustainable energy transition

초록

This study introduces PyPSA-Korea, an open-source energy system model with high temporal and spatial resolution designed to support Korea's sustainable energy transition. Developed using the Python for Power System Analysis (PyPSA) and PyPSA-Earth frameworks and incorporating public datasets, PyPSA-Korea facilitates both operational and investment planning. It enables regional siting and expansion of integrated power generation, transmission, and energy storage systems (ESS)—a critical requirement for renewable energy integration in Korea. The model was validated against historical data from 2023 and applied to a 2036 scenario aligned with the Nationally Determined Contribution and the Basic Plan for Long-Term Electricity Supply and Demand. PyPSA-Korea provides a flexible and robust framework for research and policy analysis on macro-level energy systems. The results emphasize the necessity of renewable energy deployment, transmission network reinforcement, and ESS expansion to mitigate intermittency and achieve carbon emission reduction targets. By offering an open and high-resolution modeling framework, PyPSA-Korea overcomes the accessibility barriers associated with closed-source models and is a valuable tool for evidence-based policy analysis and strategic decision-making for a sustainable energy transition in Korea. © 2025 The Authors
