Abstract： To meet the demand for rapid risk assessment in power systems under massive operational scenarios and investigate the role flexible resources in power-energy balance， this study introduces the concept flexible operation domain for renewable energy and proposes a construction method that accounts for the system's potential balance risks. By transforming the challenging decision-dependent uncertainty set into a decision-independent uncertainty set，a twolayer robust optimization model that considers potential balance risks is established. The upperlayer model aims to minimize operational costs and balance risks under forecasted scenarios while determining the upper and lower boundaries the flexible operation domain for renewable energy. The lower-layer model verifies the system’s worst-case balance conditions within the boundaries the flexible operation domain for renewable energy derived from the upper layer.The C&CG algorithm is employed for effective solving. Case study results demonstrate that the proposed method can delineate the balance risk boundaries the system under the impact the randomness new energy. The obtained flexible operation domain covers 99% potential deviations in most time periods，thereby assisting in quickly identifying risk-free renewable energy operation modes and providing warnings about imbalanced time periods and quantities for risky operation modes. Furthermore， the introduction energy storage devices can expand the flexible operation domain for renewable energy，effectively enhancing the system’s renewable energy accommodation capability and load supply capacity. Storage capacities 10% ， 20% ，and （204号 40% increase the flexible operation domain for renewable energy by 1. 93% ， 7.82% ，and （204号 10.44% ，respectively.
