日本語

本論文は、韓国の電力市場における価格シグナルの構造的歪みを分析し、再生可能エネルギーの統合を阻害している要因を特定する。提案される改革パッケージは、地点別限界価格制度の導入、リアルタイム市場の確立、市場と系統運用の統合、入札方式の変更を含む。これらの改革を一体的に実施することで、韓国のエネルギー政策目標に沿った一貫した市場設計が可能になると論じる。

English

This paper examines structural price distortions in Korea's electricity market, identifying barriers to renewable energy integration. It proposes a reform package including locational marginal pricing, a real-time market, integrated market and system operations, and a shift to price-based bidding. The authors argue that joint implementation is necessary to align market signals with Korea's energy transition goals.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本でも電力市場改革が進む中、韓国の事例は地点別限界価格やリアルタイム市場の導入など、類似の課題を抱える日本にとって参考になる。特に、分散型電源の増加に伴う系統制約の顕在化への対応として、本論文の分析は示唆に富む。

In the global GX context

Korea's electricity market design challenges mirror those in many countries pursuing renewable integration. The proposed reforms—especially locational pricing and real-time markets—provide a blueprint for market redesign that could inform global discussions on decarbonizing electricity systems.

👥 読者別の含意

🔬研究者:The paper offers a detailed case study of market distortions and a comprehensive reform framework for energy transition in regulated electricity markets.

🏢実務担当者:Utilities and grid operators can learn from the proposed reforms to manage transmission constraints and integrate renewable energy more efficiently.

🏛政策担当者:Policymakers in countries with similar market designs can use this analysis to evaluate the need for locational pricing and market restructuring to meet climate targets.

📄 Abstract（原文）

Structural distortions in price signals within the Korean electricity market, governed by a cost-based pool (CBP) and a uniform pricing mechanism, fundamentally undermine the nation's energy transition goals. The current market design fails to reflect transmission constraints, real-time supply and demand dynamics, and generator-specific costs, leading to inefficient resource allocation and hindering long-term investments in renewable energy and grid flexibility. This paper identifies the key drivers of these distortions and proposes a holistic reform package to enhance market efficiency. The package includes four key reforms: \stepcounter{excep}(\roman{excep}) introducing a locational marginal pricing system to manage transmission constraints; \stepcounter{excep}(\roman{excep}) establishing a real-time market to reflect temporal value; \stepcounter{excep}(\roman{excep}) integrating market and system operations to resolve inconsistencies; and \stepcounter{excep}(\roman{excep}) transitioning from CBP to a price-based bidding system. Each reform targets a distinct source of inefficiency. The broader contribution of this study, however, lies in showing that, under the current Korean market design, the market cannot readily provide effective price signals. These reforms therefore need to be implemented jointly to establish a coherent market design in which price signals are aligned with Korea's energy policy objectives.
