In terms of composition, the grid energy system sand table model typically includes energy storage equipment (e.g. batteries, super capacitors, fly-wheel energy storage devices, etc.), energy conversion units (e.g. reversers, transformers, etc.), monitoring and management systems, and electrical circuits and conduits connecting these equipment. Through fine design and production, these components accurately reset the layout and connection of the actual system, enabling visitors to visualize the overall structure of the grid energy system.

In terms of working principles, the sandpad model simulates the charging process of grid energy systems and energy flow paths through dynamic demonstrations and light effects. For example, during the charging phase, the light in the model is activated in sequence according to the logical sequence set to simulate the process by which the power flows from the grid to the storage equipment; when discharged, the light flows backwards, showing the scenario in which the energy is released by the storage equipment to the load or grid. This dynamic demonstration has greatly enhanced the taste and attractiveness of the model, making the complex power grid energy principles easy to understand.
