Identification model for weak areas of transient energy balance in EESs based on dynamic grid partitioning

In response to the high uncertainty of large-scale new energy output in electrical system (EES) and weak controllability at multiple time scales, this paper proposes a grid identification model for transient balance EESs based on partitioning, which has an increasingly complex impact areas sending-end network. First, accumulation port during faults propagation mechanism were studied, EES was established. Then, considering support requirements nodes, partitioning Afterward, characteristics model, constructed. Finally, actual operating data, numerical simulations conducted, results showed that proposed can meet stability analysis characteristic operation power grids.
