What is electrical energy storage (EES)?

Electrical Energy Storage, EES, is one of the key technologies in the areas covered by the IEC. EES techniques have shown unique capabilities in coping with some critical characteristics of electricity, for example hourly variations in demand and price.

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 , , .

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 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.

What are some good books about electrical energy storage?

Electr. Energy 21st Century, IEEE; 2008. p. 1–8. James P, Dunlop PE. Batteries and charge control in stand-alone photovoltaic systems – fundamentals and application. Technical report. Florida Solar Energy Center. Sandia National Laboratories; 1997. Paul B. The future of electrical energy storage: the economics and potential of new technologies.

What is the third class of energy storage?

The third class, the GWh class, will be covered in section 4.2.2. Besides time shifting with energy storage, there are also other ways of matching supply and demand. With a reinforced power grid, regional overproduction can be compensated for by energy transmission to temporarily less productive areas.
