Abstract

This study investigates operational challenges arising from high renewable energy integration in incremental distribution networks, focusing on coordinated optimization of “source-grid-load-storage” systems. By analyzing system characteristics and operational challenges, the research develops refined models for distributed generation, flexible loads, and energy storage systems. An optimized scheduling framework is established with objectives of cost-effectiveness, stability, and low-carbon performance, incorporating a multi-time-scale collaborative scheduling approach and a full-cycle optimization strategy that includes day-ahead planning, rolling adjustments, and real-time control. The findings demonstrate that this methodology significantly enhances system efficiency, improves renewable energy utilization, and ensures power supply stability, providing theoretical support and practical guidance for optimizing incremental distribution network operations.
