“…The chemical composition is almost similar to Ni-Cd except the hydrogen ion negative electrode plate in Ni-MH which gives the technical features such as: specific energy of 60−120 Wh/kg, increased lifecycles (∼3000) with 70-90% efficiency and very low internal resistance. Due to which they are suitable for many sensitive electronic devices [138]. Also for applications of hybrid EVs, portable and mobile devices the sealed Ni-MH batteries are attractive due to robust and safer characteristics compared with Li-ion batteries [138], [139].…”

Also for applications of hybrid EVs, portable and mobile devices the sealed Ni-MH batteries are attractive due to robust and safer characteristics compared with Li-ion batteries [138], [139]. The limitations of Ni-MH are: high self-discharge rate (5-30% per month), sensitive to overcharging and DoD, time dependent nature and rapid lifecycle degradation.…”

“…The limitations of Ni-MH are: high self-discharge rate (5-30% per month), sensitive to overcharging and DoD, time dependent nature and rapid lifecycle degradation. The cost will increase further, if, timer based or smart chargers are employed for avoiding the overcharging or DoD of NiMH batteries [138], [140].…”

It is an exciting time for power systems as there are many ground-breaking changes happening simultaneously. There is a global concensus in increasing the share of renewable energy-based generation in the overall mix, transitioning to a more environmental-friendly transportation with electric vehicles as well as liberalizing the electricity markets, much to the distaste of traditional utility companies. All of these changes are against the status quo and introduce new paradigms in the way the power systems operate. The generation penetrates distribution networks, renewables introduce intermittency, and liberalized markets need more competitive operation with the existing assets. All of these challenges require using some sort of storage device to develop viable power system operation solutions. There are different types of storage systems with different costs, operation characteristics, and potential applications. Understanding these is vital for the future design of power systems whether it be for short-term transient operation or long-term generation planning. In this paper, the state-of-the-art storage systems and their characteristics are thoroughly reviewed along with the cutting edge research prototypes. Based on their architectures, capacities, and operation characteristics, the potential application fields are identified. Finally, the research fields that are related to energy storage systems are studied with their impacts on the future of power systems.INDEX TERMS Storage systems, electric vehicles, power system optimization, market liberalization, renewable energy, new operation schemes, power system planning.
