In order to solve the difficulties in ensuring supply,balance and reasonable utilization of renewable energy in a power system with a high proportion of the renewable energy,considering the characteristics of the renewable energy and the differences in multi-type flexible adjustable resource characteristics,the paper proposes a refined time series simulation model and probabilistic power and energy balance method with the consideration of the flexible interaction of source-grid-load-storage,establishes a complete calculation framework for the renewable energy integration,and analyzes the main factors affecting the renewable energy integration capabilities.Taking the planning system of a major province with renewable energy power generation in 2025 as an example to verify the method,accurate data for a variety of operating scenarios are obtained,balance indicators are effectively calculated such as renewable energy abandoned electricity and power demand,and some suggestions are provided for power system planning and construction.
