it is a type of UPS having a long life battery size i.e storage cylinders store air and this storage air hit the turbine plate at a very high pressure and turbine is connected to the shaft generator which produce electricity usable for DC loads

Storing Electrical energy have been the subject of many researches during few past years since
more and more clean, cheap however not very stable renewable energy sources are being
introduced to the market. With a proper storage option the excess energy produced during off-peak
hours can be used for peak shaving thus reducing the total required capacity for the grid. For this
purpose the technologies has been implemented commercially so far, Compressed Air Energy
Storage (CAES). As much as 99% of the world’s storage capacity is done by the former with a total
of 127-129 GW all around the world. The latter technology is implementable in a wide range of
scales which can deliver up to 100MW+ of power per unit. [X. Luo, J. Wang, M. Dooner, J. Clarke,
and C. Krupke, “Overview of current development in compressed air energy storage technology,”
Energy Procedia, vol. 62, pp. 603–611, 2014.] A CAES plant use excessive energy of the grid to run
compressors in order to compress the air and store it in a reservoir. Later on during peak periods the
energy of stored compressed air is returned to the grid using an expander (e.g. a turbine) coupled
with a generator. Other than power-plants which use this technology, developments has been carried
out in order make this type of storage possible in smaller scales for a more distributed solution
Pakistan is facing the worst power crises since last one decade. The major cause is the increase
in electrical demand of three to five times without extra generation plant being added to the
Compressed air energy storage (CAES) is a technique for supplying electric power to meet
peak load requirements of electric utility systems. It incorporates a modified state-of-the-art
gas turbine and an underground reservoir that may be an aquifer, a salt cavity or a mined hard
The objective of this research is to:
Design, developed and Analysis of a small scale compressed air energy storage
prototype for a small home as an un-interrupted power supply system.
The system is composite technology, which composes of energy storage system and electric
power supply system. the principle is based on compressing and storage of air during the hours
when electricity is available from the grid supply and using the stored energy to generate
electricity by means of a turbine-generator system during the hours of load shedding. the
essential components of the entire system consists of a source to make compress air and storage
cylinders. the output of the storage cylinders is coupled to the turbine through valve and regulator.
the turbine is coupled to the generator. regulated air form the compressed air cylinder is allowed
to flow to the turbine system by opening of a valve either operated manually or automatically
during the time when the supply is interrupted from the grid mains.
In the present work, the idea is to use the concept of renewable energy resources such as solar
and wind. the energy will transfer from the renewable energy resource (solar plant) to the CAES
system drives the air compressor engine to produce high-pressure compressed air to be stored in
cylinders. CAES is used on demand or used in during the peak periods or when the solar energy
is not available to generate power by a special wind turbine coupled with generator as shown in
