Abstract

Abstract:

Establishing accurate electromagnetic transient simulation models for energy storage units in power stations is critical for effectively regulating and operating renewable energy and energy storage facilities. It is also a key strategy for enhancing renewable energy utilization and ensuring the safe operation of power grids. Currently, most electromagnetic transient modeling for energy storage systems relies on foreign simulation platforms, with limited analysis or accuracy verification based on the localized Advanced Digital Power System Simulator (ADPSS) electromagnetic simulation platform. Using a specific energy storage power station as an example, this paper employs the ADPSS platform to develop an electromagnetic transient simulation model for the energy storage power plant. Through hardware-in-the-loop (HIL) testing of the energy storage system's real controller, a simulation model is constructed that accurately reflects the steady-state and transient operational characteristics of the actual energy storage system. Comparative analyses are conducted between results from real single turbine tests and those of the ADPSS-HIL encapsulated model under different operational conditions. The study evaluates transient characteristics such as low voltage ride-through (LVRT) and high voltage ride-through (HVRT) performance. By adjusting the parameters of the ADPSS-HIL encapsulated model, the wave ADPSS-HIL encapsulation model shape data and turbine test error are adjusted to comply with relevant standards, resulting in the establishment of an accurate electromagnetic transient-based model. The proposed electromagnetic transient simulation model for the energy storage unit improves the accuracy of grid simulation calculations and ensures that results can effectively guide production operations.
