Large amounts of renewable energy resources is a step necessary to achieve a clean and secure electric power industry. The storage in future grids is receiving the attention from the system designers, grid operations and regulators.
need for storage:
The meeting of the North American Electric distribution association suggested the use of storage from large-scale bulk-storage systems to small units at
or near the point of load. The plug-in hybrid electric vehicles will also drive the development of the grid.
Spectrum of Electricity Storage
some form of energy storage everyday is required by each and every person in the industrialized countries. For eg, battery power is required by every electronic device. The electric cars are having a great impact on the evolution of the grids as the higher power use in cars is demanding the upgrading of the grids.
lead-acid batteries are finding application in (UPS) backup for data centers and automotive starting batteries. The lithium-ion is used in laptop batteries and power tools
Compressed Air Energy Storage
This is a is a peaking gas turbine power plant that consumes less than 40% of the gas used in a combined-cycle gas turbine. Here, the compressed air is blended with the input fuel to the turbine. With this, the plant’s output can produce electricity during peak periods at lower costs by compressing air during off-peak periods when energy prices are very low.
