Abstract

Existing studies on freight electrification largely rely on centralized architectures or simplified uncertainty models, leaving a gap in decentralized energy–mobility coordination under volatile electricity prices and privacy constraints. This study develops a decentralized optimization framework for coordinated operation of a heavy-duty electric truck aggregator and an eco-industrial park under concurrent market and fleet uncertainty. A hybrid distributionally robust–stochastic programming structure is adopted, where locational marginal price uncertainty is modeled through an uncertainty-budget robust layer, while fleet arrival, departure, and state-of-charge variability are represented via scenarios. The problem is decomposed using an alternating direction method of multipliers-based distributed algorithm to preserve autonomy and limit information exchange to tie-line power flows. Numerical results confirm stable convergence within approximately 130 iterations. When the price uncertainty budget spans the full 24-hour horizon, aggregator net profit decreases by 41% and eco-industrial park operating cost increases by 9% relative to deterministic pricing, without feasibility loss. The results demonstrate that integrating robust price hedging with stochastic fleet modeling enables economically consistent decentralized coordination under adverse market conditions.
