Supercapacitors (or electric double-layer capacitors) are high-power energy storage devices that store charge at the interface between porous carbon electrodes and an electrolyte solution. These devices are already employed in heavy electric vehicles and electronic devices, and can complement batteries in a more sustainable future.
In this work, we propose a co-phase traction power supply system with super capacitor (CSS_SC) for the purpose of realizing the function of energy management and power quality management in
Electrostatic double-layer capacitors (EDLC), or supercapacitors (supercaps), are effective energy storage devices that bridge the functionality gap between larger and heavier battery-based systems and bulk capacitors. Supercaps can tolerate significantly more rapid charge and discharge cycles than rechargeable batteries can.
In contrast, capacitors can be charged and discharged at a much faster rate, but the amount of energy they can store is significantly less than batteries. Supercapacitors overcome these limitations, ofering energy densities that are comparable to batteries and power densities that are comparable to capacitors.
Besides the topology, the energy management and control strategies used in HESS are crucial in maximising efficiency, energy throughput and lifespan of the energy storage elements [33-37]. This paper reviews the current trends of battery-supercapacitor HESS used in standalone micro-grid.

Once modular multilevel converter (MMC) dc-side short-circuit fault occurs, the conventional fault ride-through (FRT) strategy indeed eliminates dc fault current quickly with the utilization of full-bridge submodules. Thereupon, ac-side active power declines sharply. However, instantaneous high power outage will cause ac-grid power and frequency
3. Electrochemical capacitor background. The concept of storing energy in the electric double layer that is formed at the interface between an electrolyte and a solid has been known since the 1800s. The first electrical device described using double-layer charge storage was by H.I. Becker of General Electric in 1957.
Also, they exhibit remarkable EC and capacitive properties, achieving a maximum high specific capacitance (C sp) of 310 F g –1 with a current density of 1.0 A g –1 in a 3.0 M KOH solution.
