The most common mechanical energy-storage technologies are pumped-hydroelectric energy storage (PHES), which uses gravitational potential energy; compressed-air energy storage (CAES), which uses the elastic potential energy of pressurized air; and flywheels, which use rotational kinetic energy.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.
While many papers compare different ESS technologies, only a few research [152,153] studies design and control flywheel-based hybrid energy storage systems. Recently, Zhang et al. present a hybrid energy storage system based on compressed air energy storage and FESS.
Accepted: 02 March 2024 Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
Pumped hydro and compressed air energy storage technologies are mature, cost effective and reliable technologies that are used for large scale storage with frequent cycling capabilities. However, research is still needed to improve their round-trip efficiencies. In PHES systems, advances in turbine design are needed to improve performance.
A flywheel is a mechanical battery that is made up of a spinning mass around an axis. The flywheel works through the principle of storing energy in the form of kinetic rotational energy .
Khodadoost et al. suggest that flywheels are favorable options for integration with wind and PV systems compared to battery energy storage systems since variations in their output power occur in a short period of time.

Belarus is a net energy importer. According to IEA, the energy import vastly exceeded the energy productionin 2015, describing Belarus as one of the world's least energy sufficient countries in the world. Belarus is very dependent on Russia.
Primary energy use in Belarus was 327 TWh or 34 TWh per million persons in 2008. Primary energy use per capita in Belarus in 2009 (34 MWh) was slightly more than in Portugal(26 MWh) and about half of the use in Belgium(64 MWh) or Sweden(62 MWh). Electricity consumed in 2021 was 32.67 billion kWh, 3,547 kWh per capita.
Belarus is involved in implementing numerous interstate and international treaties in energy, including participation in the Commonwealth of Independent States (CIS) agreement on the co‑ordination of interstate relations in the power sector, and the treaty on the parallel operations of power systems of the CIS.

An equivalent consumption minimization strategy is proposed and verified for optimization. This paper describes a hybrid tram powered by a Proton Exchange Membrane (PEM) fuel cell (FC) stack supported by an energy storage system (ESS) composed of a Li-ion battery (LB) pack and an ultra-capacitor (UC) pack.
The tram mainly comprises the energy storage system, traction system, and auxiliary system, and the specific structure is shown in Fig. 1. As the sole power source of the tram, the battery pack can supply power to the traction system and absorb the regenerative braking energy during electric braking to recharge the energy storage system.

Therefore, this paper proposes a multi-objective optimization method for the tram's driving strategy to reduce operational energy consumption and extend battery life. The method describes the optimization problem as second-order cone programming (SOCP).
