This study proposes a three-stage chronological production simulation method to enhance inter-provincial resource coordination. The core innovation lies in combining the “multi-time-scale decomposition” strategy with the “intra-provincial balancing and inter-provincial mutual assistance” mechanism. A three-stage optimization model for annual chronological production simulation is constructed. Specifically, the inter-provincial monthly medium-term mutual assistance stage takes into account the constraints of inter-provincial monthly transaction electricity volume, so as to adapt to the current situation in China where inter-provincial medium-term power transactions are mostly carried out on a monthly cycle. Simulation analysis was conducted based on a case study built with actual data from the Chongqing and Sichuan power grids in the southwestern region of China, which verifies the effectiveness of the proposed method.
