Towards Implementation of Smart Grid: An Updated Review on Electrical Energy Storage Systems

Abstract

A smart grid will require, to greater or lesser degrees, advanced tools for planning and operation, broadly accepted communications platforms, smart sensors and controls, and real-time pricing. The smart grid has been described as something of an ecosystem with constantly communication, proactive, and virtually self-aware. The use of smart grid has a lot of economical and environmental advantages; however it has a downside of instability and unpredictability introduced by distributed generation (DG) from renewable energy into the public electric systems. Variable energies such as solar and wind power have a lack of stability and to avoid short-term fluctuations in power supplied to the grid, a local storage subsystem could be used to provide higher quality and stability in the fed energy. Energy storage systems (ESSs) would be a facilitator of smart grid deployment and a "small amount" of storage would have a "great impact" on the future power grid. The smart grid, with its various superior communications and control features, would make it possible to integrate the potential application of widely dispersed battery storage systems as well other ESSs. This work deals with a detailed updated review on available ESSs applications in future smart power grids. It also highlights latest projects carried out on different ESSs throughout all around the world.

Recent Progress in Electrode Materials for Sodium‐Ion Batteries

“…In addition, many prototypes of grid-scale LIBs (approximately tens of megawatt-hours) that are connected to renewable energy sources such as solar and wind power have appeared on the market. [12][13][14] However, there are several signifi cant challenges facing LIBs for their application in grid-scale ESSs. One of the greatest issues to date is the cost with respect to not only the processing/fabrication but also the raw materials.…”

Akilli Şebekelerde Enerji̇ Depolama Uygulamalarinin Önündeki̇ Firsatlar Ve Karşilaşilan Zorluklar

“…Rüzgâr ve güneş enerjisi gibi YEK, genellikle kesintili ve kararsızdırlar, dolayısıyla elektrik güç sistemine değişken güç sağlarlar [8]. Güç sistemine enerji depolama sisteminin eklenmesi, fazla enerjiyi tutarak ve güç eksikliği olan yere ileterek yenilenebilir enerji gücüne katkıda bulunabilir.…”

Negotiation strategy for discharging price of EVs based on fuzzy Bayesian learning

“…According to the investigation, it has been estimated that the proportion of EVs in the USA can reach 35, 51 and 62% of the total number of vehicles by 2020, 2030 and 2050 [4]. Moreover, individual EVs are utilised only 4% of the time for transportation, making a large population of EVs potentially available in the remaining 96% of time for dispatching of electric system [5]. EVs regarded as energy storage device can provide fast and accurate responses for frequency regulation and spinning reserves, and various institutions and governments have issued relevant incentive policies to vigorously develop V2G technology [6].…”
