Electric energy storage

What are electrical energy storage systems (EESS)?

Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years. EESS are starting to be used for other purposes.

What is electrical energy storage?

Electrical Energy Storage is a process of converting electrical energy into a form that can be stored for converting back to electrical energy when needed (McLarnon and Cairns, 1989; Ibrahim et al., 2008). In this section, a technical comparison between the different types of energy storage systems is carried out.

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.

Can electrical energy storage solve the supply-demand balance problem?

As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.

Why is electric energy storage so popular?

Increased interest in electrical energy storage is in large part driven by the explosive growth in intermittent renewable sources such as wind and solar as well as the global drive towards decarbonizing the energy economy.
