Dual-time-scale dynamic model for analyzing flexible power generation capacity evolution

The invention relates to a double-time-scale dynamic model for analyzing flexible power generation capacity evolution, and belongs to the technical field of power system data analysis. A system dynamic model is constructed, an objective function is established with social benefit maximization, peak load constraints, energy demand constraints and reliability constraints are considered in constraint conditions, and a dynamic evolution model considering multiple constraints is established; flexibility requirements are formulated, climbing constraints are considered and embedded into the capacity market, and the requirements of different generators for the climbing ability are calculated; and embedding the random unit combination model into system dynamics to form a dual-time-scale simulation system. The method can reflect the flexible unit capacity change of the power grid, and facilitates the making of related decisions. The system flexibility requirements of wind power generation and solar power generation are
