Pumped storage stores electricity in the form of potential energy. The basic principle of energy conversion is shown in Fig. 1. In pump mode (charging), electrical energy is taken from the electrical grid to feed a motor that mechanically drives a pump. The water is pumped from the lower basin into the upper basin.
The power demand in modern days is increasing dramatically and to meet this ever-increasing demand different methods and alternate solutions are implemented to generate and store the energy efficiently. Also, proper management of generation and demand is essential for the stable and secure operation of the power system. In this context, the role
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
Mechanical energy storage, in contrast, tends to be inexpensive at large scales due to the use of relatively low-cost materials (e.g., concrete and steel) and low-cost storage media (e.g., water, air), and due to long device lifetimes.

There are two main types of mechanical energy. 1. Potential Energy: It is the energy stored in an object due to its position. Gravitational potential energy due to Earth''s gravity is a common type of potential energy. It depends on the object''s height from the Earth''s surface. For example, an apple in an apple tree has the maximum

Abstract. A flywheel energy storage (FES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems that is most appropriate for small- and medium-scale uses and shorter period applications. In an FES system, the surplus electricity is stored in a high rotational velocity disk-shaped flywheel.
