Working principle of energy storage device generator

What is elastic energy storage – electric power generation system?

With the elastic energy storage–electric power generation system, grid electrical energy can drive electric motors to wind up a spiral spring group to store energy when power grid is adequate, and the stored energy can drive electric generators to generate electrical energy when power grid is insufficient. The working principle is shown in Fig. 2.

How does a generator turn electrical energy into electrical energy?

When external electric energy is abundant, the motor is driven by an electric electronic device to rotate the flywheel and convert the electrical energy into storable mechanical energy. When energy needs to be released, the flywheel reverses the generator and transforms the stored mechanical energy into electrical energy.

How does a PV storage system work?

Regardless of the time of energy production, the storage provides the energy generated by the PV generator to electrical appliances. Supply and demand can be adjusted to each other. The integrated storage system is designed to cover 100 % of the demand with the energy generated by the PV system during the summer.

How do generators & consumers connect to a power grid?

Generators and consumers are connected through power grids and form a power system. In function of the loca-tions and the quantities of power supply and de-mand, much power fl ow may happen to be con-centrated into a specifi c transmission line and this may cause congestion.

What are the functions of elastic storage device using spiral spring?

The principal functions of elastic storage device using spiral spring are energy storage and transfer in space and time. Elastic energy storage using spiral spring can realize the balance between energy supply and demand in many applications.

What is mechanical storage?

Mechanical storage refers to storage of excessive mechanical or electrical energy in a medium as kinetic energy, potential energy or other energy forms. Pumped storage in a hydropower plant, compressed air energy storage and flywheel energy storage are the three major methods of mechanical storage .
