Abstract
Even if electrical energy storage technologies have been used since the end of the 19th century, a new interest has grown recently, due to the necessity of adapting the electrical system to the new paradigm. The massive increase in the use of renewable and distributed sources of energy, coupled with the emerging requests for lower power costs and higher reliability to the system, calls for new ways of producing and distributing energy. All developed countries are busy, at the moment, to win the run for the implementation of a smart grid, i.e. a new generation grid able to deal with intermittent electricity production (for example solar, wind), decentralised small-scale sources, multidirectional electricity flows, remote control and real time management. Storage devices represent the balancing element which allows responding in an economic way either to the demand or to the offer side. This paper presents a review of the electrical storage technologies, showing benefits and critical aspect of energy storage, in respect of the new need of the energy sector to become smart.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
