Overview of medium scale energy storage systems

The paper is a summary of the research conducted so far on the ultrafast charging issues of electric vehicles with the main emphasis on the infrastructure. In order to estimate the load curve and peaks resulting from high charging rate, simulations are carried out initially to determine energy and power ratings. Energy storage options for filtering out the perspective peaks are discussed with applicable power interfaces between the grid, the vehicle and the storage buffer. Finally, an ultrafast charging architecture based on cascaded H-bridge converters is proposed.

“…For homes in general we believe the battery bank as part of the HES is the most convenient choice given the cost and modularity provided by this ESS. Particularly relevant when it comes to ESS technology review are (see [12], [13], [14], [15], [16], [17] and [18]) all presenting important contributions to the subject.…”

“…Once the project is decided upon, there comes the need to deal with system sizing, optimization of different system components and of the system as a whole, including energy system design, optimal control of HES. By choosing the right components and the appropriate system configuration, their costs can be minimized through proper equipment sizing and load matching (see [12], [13], [14], [15], [16], [17] and [18]). The bottom line is to make the most efficient use of NCRE sources and the HEPS configuration chosen throughout the lifetime of the system.…”

Abstract:According to seismologists Chile has yet to face another big earthquake in the very near future, yet the country remains largely unprepared against massive electric power systems brake-down. The problem lies in the centralized electric power systems and the lack of adequate technologies and back-up/emergency power systems for disaster recovery. The flaws that are built into the very fabric of the presently centralized power systems were on full display in the February 27th earthquake in Chile. Nowhere it becomes more evident that hugely centralized power generation and distribution systems are extremely vulnerable and ineffective to disruptions from natural disasters, human error or other calamities. The large power networks that once proved very efficient and secure, are now at the center of discussion fueling the need for decentralization and the rapid growth of distributed generation (DG). Highly decentralized, diversified and DG-oriented energy matrix is notoriously much better suited to withstand these disasters. In centralized electric power grids, servicing large metropolitan areas, albeit with some but limited differentiation in service, can only be on or off, so either everyone gets power or no one does. This makes recovering power service in an emergency situation a much more difficult task. On the other hand, decentralized power systems (DPS) reduce the obstacles to disaster preparation and recovery by allowing the focus to shift first to critical infrastructure and then to flow outward to less integrated outlets. A DG-based model for a smart micro-grid based on hybrid electric power systems (HEPS) using both renewable energy technologies (RET) and conventional power generation units is presented. The hybrid energy system may be portable or fixed in one place, highly reliable, easy to assemble, modular, flexible and cost-effective solution, that is ready-to-run and go to where it is needed to supply power in natural disaster.

“…The availability of having energy storage systems (ESS) [1,2] is a key factor for establishing new operation strategies in electric distribution grids related with the hot topic of Smart Grids. This ESS will do easy to integrate distributed generation systems based in renewable energies placed in houses, residential and commercial building and also will contribute to have some control on the load profile, and so achieving a better overall performance and utilization of the distribution grid.…”

Abstract. This paper presents a Smart Storage System able to manage the energy and the smart home devices of a house for optimizing the local consumption of energy, even if there is not renewable generation. The proposed system is composed by two main systems. On the one hand, the Local Energy Management units that will be located in the houses, which are able to maintain the power consumption under a maximum reference value and to switch on/off the devices in the house by using domotic protocols. On the other hand, the Central Energy Management and Intelligent System, that receives operation data from each local unit, analyzes them using behavioral and optimization algorithms and determines the best way in which each local unit has to operate, communicating the operation references back to them.
