Low-carbon Robust Optimization Strategy for Coordinated Operation of Mobile Energy Storage and Distribution Networks
To address the low-carbon scheduling requirements of distribution networks with high renewable energy penetration
a two-stage collaborative optimization method integrating the spatiotemporal flexibility of mobile energy storage (MES) is proposed. First
a joint capacity-location planning model for MES under power-transportation coupling is constructed. By leveraging graph theory to analyze transportation topology
a cost-minimized pre-configuration scheme is determined. Second
a dynamic optimization model for the distribution network incorporating low-carbon costs is established. An improved carbon emission flow theory is proposed to quantify nodal carbon potential
enabling precise tracking of source-load carbon footprints. To address uncertainties in wind/solar power output
a data-driven distributionally robust optimization method based on Wasserstein distance is adopted. Efficient solution is achieved through the dual transformation of the bi-level model and second-order cone relaxation. Finally
case studies on an IEEE 33-node distribution network coupled with a 25-node transportation network demonstrate that the proposed strategy reduces system operating costs by 6.2% and decreases carbon emission intensity by 28.9%.
