The peak sharing pressure on power systems is intensified by the integration of renewable energy, making massuve distributed flexible resources regarded as crucial for virtual power plant（VPP）planning and operation. A VPP model addressing renewable energy uncertainty is proposed：an improved Transformer method forecasts renewable output, a distributed resource aggregation scheme is designed, and a corresponding control strategy balancing security and economy is developed. Validation using real regional data and grid topology is used to confirm that the scheme effectively supports renewable energy utilization and system stability.
