Prospects of electrified energy storage

What is the future of electricity storage?

Over the years, new technologies for storing electricity were emerging, which have led to a variety of storage systems today, all differing in the application, costs, and profitability. It is forecasted by International Energy Agency (IEA) that global installed storage capacity will expand by 56% in the upcoming years .

Why is energy storage important in electrical power engineering?

Various application domains are considered. Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations.

What are the benefits of large-scale electrical energy storage systems?

Certainly, large-scale electrical energy storage systems may alleviate many of the inherent inefficiencies and deficiencies in the grid system, and help improve grid reliability, facilitate full integration of intermittent renewable sources, and effectively manage power generation. Electrical energy storage offers two other important advantages.

Are energy storage systems profitable?

Recent energy storage literature lacks profitability and economic assessments of storage systems. Most of the literature covers dispatching , modeling renewable generation with energy storage systems [51–54], or using mobile storage systems for unbalanced distribution grids .

What are the most popular energy storage systems?

This paper presents a comprehensive review of the most popular energy storage systems including electrical energy storage systems, electrochemical energy storage systems, mechanical energy storage systems, thermal energy storage systems, and chemical energy storage systems.

How important is sizing and placement of energy storage systems?

The sizing and placement of energy storage systems (ESS) are critical factors in improving grid stability and power system performance. Numerous scholarly articles highlight the importance of the ideal ESS placement and sizing for various power grid applications, such as microgrids, distribution networks, generating, and transmission [167, 168].
