The railway station as link of electromobilty

KEYNOTE

for an increase in the energy efficiency of the system, not only causing their own functionality,
but which also derives from the individual optimization in the design of each of the teams that
comprise.
This will be complemented by the development of TIC's kind technologies which carry out the
communication of all these systems existing in the installation, allowing monitor, manage and
control the information resident in the system: energy flows, State of the storage condition
of the points of recharge, existence of faults in the system, signs of alarm, charging the user
network quality, etc.

2.4 State of the art of the technologies involved

Five are the object of study and development technological lines:
• Systems of energy storage technology
• Technology of supercapacitors

• Battery technology
• The recharging of electric vehicles (PR-VE) point technology
• Technologies of information and communication technologies (ICT)

• Technologies for energy efficiency and network quality
• E-maintenance

2.4.1 Storage systems

Energy accumulators, as its name suggests, allow to store energy in any of its forms, so that
it can be used later. In this way gets undock the demand of power generation. With respect to
the electric system, these devices improve their efficiency and reliability, absorbing the energy
produced from the network during the valleys of demand (low cost of generation), either from
intermittent renewable energy sources in case of existence of surplus, and releasing it in the
moments of greatest demand, high cost of generation or when there is no other source of
energy available. The main technologies for the purpose of storage are:

• Electrochemical batteries. (Applicable in this project)
• Supercapacitors. (Applicable in this project)
• Magnetic storage (SMES) Superconductor
• Kinetic energy (flywheels) geostructural

• Storage of compressed air
• Pumped hydropower

Taking into account that the energy requirement for this project requires a storage system
medium energy density and with a great capacity of response, only listed previous technologies
will be explored to fund the first two.
In general, energy storage devices are used basically in four scenarios:
• Increase the efficiency of electrical systems, to reduce the need for backup generation,
providing power in the daily demand peaks
• Increase the reliability of the system, to reduce the chance of outage. (Applicable in
this project)
