A power system flexibility optimization model, NEMO-China-Flexibility, was constructed in this study, integrating power system flexibility enhancement into a carbon-neutral framework for China's regional power grids. Based on regional economic development levels, energy demand intensity, renewable resource development potential, and flexibility enhancement, four distinct scenarios were designed: baseline scenario, high-penetration variable renewable energy scenario, flexibility enhancement scenario, and comprehensive scenario. The effects of flexibility enhancement were analyzed through scenario comparison. The results showed that integrated source-grid-load-storage flexibility enhancement could significantly enhance the power system's capability to address supply-demand fluctuations and improve renewable energy consumption. Among various flexibility resources, coal power was the foundational flexibility resource, while energy storage exhibited the greatest development potential. Additionally, flexibility enhancement delivered co-benefits such as reducing carbon emissions and lowering power system operational costs.
