• It is estimated that by 2050, the world’s electrical energy needs will be somewhere between 30 and 60 Terra Watts (TW) of electric power from the current 12TW [12].

 

• This kind of electric energy will require efficient and secure distributed, storage, transmission modern grid technologies in order to be delivered globally within high quality.

 

• GC (Grid Computing) technology will be necessary to provide a computational infrastructure.

 

• Grid computing is a powerful and efficient computational technology which represented as an advanced step for the previous distributing computing

 

• Grid computing as a new computing generation that uses the resources of many separated computers connected by a Network for solving such massive computation problems by making use of the underutilized resources or grid shared resources.

 

• Generation, transmission and distribution are three components of modern power system.

 

• Power generating station generates the electrical power by synchronous alternators through steam or hydro turbine.

 

• The generating stations are categorized as thermal, hydro, nuclear etc.

 

• The electric power generated at any such station has to be transmitted over a long distance to load centers that are usually cities or towns. This is called the power transmission.

 

• Electric power is generated at a frequency of either 50 Hz or 60 Hz

 

• In India the frequency is 50 Hz, in an inter connected AC power system  the rated generation frequency of all units must be the same
