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.
What is energy storage medium?
Batteries and the BMS are replaced by the “Energy Storage Medium”, to represent any storage technologies including the necessary energy conversion subsystem. The control hierarchy can be further generalized to include other storage systems or devices connected to the grid, illustrated in Figure 3-19.
What is the energy architecture for a smart house?
Figure 3-14 schematically represents the smart house, and Figure 3-15 maps a possible energy architecture for it. In smart houses mainly lead acid systems are used currently, but in the future Li-ion or NaNiCl batteries in particular may be installed because of their high cycle lifetime and their ability to deliver high peak power.
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.
How is energy stored in a superconducting coil?
The energy is stored in the magnetic fi eld created by the fl ow of direct current in a superconducting coil, which is kept below its superconducting critical temperature. 100 years ago at the discovery of superconductivity a temperature of about 4 °K was needed.
How does adiabatic heat storage work?
The storage system at the pilot facility is based on sodium nitrate, has a capacity of 700 kWh and works at a temperature of 305 °C [csp11]. In adiabatic CAES the heat released during compression of the air may be stored in large solid or liquid sensible heat storage systems.
