Energy storage in switching electrical equipment disappears

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.

What is electrical energy storage (EES)?

Electrical Energy Storage (EES) is recognized as underpinning technologies to have great potential in meeting these challenges, whereby energy is stored in a certain state, according to the technology used, and is converted to electrical energy when needed.

How are electrical energy storage technologies classified?

Classification of electrical energy storage technologies There are several suggested methods for categorization of various EES technologies, such as, in terms of their functions, response times, and suitable storage durations , , .

What can energy storage be a substitute for?

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible.

How has energy storage changed over the years?

In particular, research into compressed air energy storage grew significantly in 2012 whilst, in contrast, research into superconducting magnetic energy storage has remained relatively stable. It can also be seen that there has been a large increase in the research into renewable and energy management with EES topics.

Why is electricity storage important?

In the electricity market, global and continuing goals are CO 2 reduction and more effi cient and reliable electricity supply and use. The IEC is convinced that electrical energy storage will be indispensable to reaching these public policy goals.
