Source-Grid-Load-Storage Coordination for New Power Systems

This document explores the development and exploration of source-grid-load-storage coordination strategies for new power systems in the context of China's dual carbon goals. It highlights the challenges of traditional power systems, including high carbon emissions and insufficient adjustment capabilities, due to the randomness and volatility of renewable energy. The core idea is to break down barriers between generation, transmission, consumption, and storage to create a smart energy closed-loop system that maximizes renewable energy use, smooths load curves, and improves reliability. The document discusses development status, control strategies, and the transformation from a one-way centralized model to a two-way interactive system. It emphasizes the need for institutional and technological innovation, market mechanisms, and a collaborative evolution of technology, institution, and ecology. Specific models at regional, county, and park levels are outlined, including flexible interconnection and distributed smart grids, to address large-scale new energy integration and enhance system flexibility and efficiency.
