Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the sp. A typical system consists of a flywheel supported by connected to a. The flywheel and sometimes motor–generator may be enclosed in a to reduce friction an. Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10, up to 10, cycles of use. In the 1950s, flywheel-powered buses, known as, were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a great.

Different flywheel structures have important effects on mass distribution, moment of inertia, structural stress and energy storage density. Under a certain mass, arranging the materials as far away as possible from the center of the shaft can effectively improve the energy storage density of the flywheel rotor per unit mass.
In the future, the focus should be on how to improve the stability of the flywheel energy storage single machine operation and optimize the control strategy of the flywheel array. The design of composite rotors mainly optimizes the operating speed, the number of composite material wheels, and the selection of rotor materials.
In addition, this storage technology is not affected by weather and climatic conditions . One of the most important issues of flywheel energy storage systems is safety. As a result of mechanical failure, the rotating object fails during high rotational speed poses a serious danger. One of the disadvantages of these storage systems is noise.

The superconducting flywheel energy storage system developed by the Japan Railway Technology Research Institute has a rotational speed of 6000 rpm and a single unit energy storage capacity of 100 kW·h.
Cost ranges for a 1 MW battery storage system typically span roughly $1. 2 million, depending on energy capacity (4–8 MWh common for 1 MW output), chemistry, and permitting requirements. Understanding the financial investment required for a 1 megawatt (MW) system involves more than just the price tag of the battery cells; it requires a deep dive into component quality, installation expenses, and long-term operational value. For a typical 1MW/2MWh (2-hour) grid-interactive container using LFP batteries, the cost distribution is as follows: Battery cells & modules (40–48%) – LFP cells. Buyers typically see capital costs in the hundreds to low thousands of dollars per kilowatt-hour, driven by project size, technology, and siting. Assumptions: region, specs, labor hours. The per-unit perspective often quotes price per kilowatt.

A two-layer optimal configuration model of fast/slow charging piles between multiple microgrids is proposed, which makes the output of new energy sources such as wind power and photovoltaic in the microgrid match the EVs charging load, thus inhibiting the phenomenon that the EVs aggregation charging leads to the steep increase of grid climbing.
Considering the power interdependence among the microgrids in commercial, office, and residential areas, the fast/slow charging piles are reasonably arranged to guide the EVs to arrange the charging time, charging location, and charging mode reasonably to realize the cross-regional consumption of renewable energy among multi-microgrids.
However, the cost performance of energy storage systems is currently low and it has a limited operating cycle, so under the condition of stable operation of the microgrid, it is of great significance to reasonably configure and optimize the energy storage capacity .
By arranging to charge piles of different types and capacities in different microgrid areas and formulating different charging price strategies, it can satisfy the differentiated demands of EVs users, promote EVs users to reduce charging costs through orderly charging, and help the rapid development of electric vehicles.
Therefore, the proposed two-layer model realizes the optimal configuration of fast/slow charging piles in multi-microgrid areas, effectively reduces the EVs charging cost, reduces the impact of the EVs charging load on microgrids, improves the operation safety of microgrids, and increases social welfare.
