エタンクラッキングの電化による産業脱炭素化において、化学プラントのマイクログリッドと再生可能エネルギー電源を統合するためのプライバシー保護型分散フレームワークを提案。ADMMと補助システムレベルペナルティを用いて収束を加速し、各サブシステムが最小限の信号のみを共有することで最適性のギャップを評価。テキサス州の実データを用いた数値実験により、データ分離が一貫して小さな最適性ギャップをもたらすことを示した。
English
This paper proposes a privacy-friendly decentralized framework for integrating electrified chemical plant microgrids with renewable-driven power systems. Using ADMM with an auxiliary system-level penalty, it enables joint optimization of unit commitment and microgrid scheduling while preserving data confidentiality. Numerical experiments on the Texas transmission network with 26 chemical plants show that data isolation results in consistently small optimality gaps and load-dependent emissions impacts.

📄 Abstract（原文）
Electrification of ethane cracking offers a promising pathway to industrial decarbonization, provided that the electricity is sourced from renewable energy. However, integrating electrified chemical plant microgrids with a decarbonized power grid requires joint operations planning between Independent System Operators and chemical plants, which is hindered by the highly confidential nature of plant operational data. In this paper, we propose a privacy-friendly decentralized framework based on data isolation that jointly optimizes the Unit Commitment problem in the power system and microgrid scheduling in electrified ethane cracker plants. The framework employs the Alternating Direction Method of Multipliers, augmented with an auxiliary system-level penalty that accelerates convergence, allowing each subsystem to solve its local subproblem and share only minimal coordination signals. To reflect real-world conditions, numerical experiments are conducted on the ACTIVSg2000 test case, a synthetic model of the Texas transmission network, with 26 chemical plants identified from Texas mapped to their nearest grid connection points. In doing so, we characterize the cost of privacy-friendly decomposition on joint power and chemical system decisions, showing that data isolation results in consistently small optimality gaps, and that its emissions consequences are load-dependent and non-monotone.
