The electrical grid

Thomas Edison created the world's first power plant in New York in 1882, and after several unsuccessful attempts, he succeeded in generating a continuous electric current. "i have not failed i just found 10000 ways that won't work meaning."


  • Importance of interconnected electricity network
In all countries of the world, the power stations within each country are connected together by a high voltage transmission network, so that all generators are connected to one network. All loads are taken from the same network
     The objective from this method of connecting the generating stations together. If each station is responsible for a particular city, the exit of this station from service for any reason means the loss of electrical energy in this city.
    The main benefit of connecting several networks together is to reduce the spinning reserve of each network, thereby reducing the investment spent on building new plants to meet demand without compromising the safety and reliability of the associated networks.
   The interconnection is also aimed at reducing pollution of the environment. 
  • Main features of electrical connection
      The main advantage of this interconnection is strongly demonstrated in the Blackout cases. This connection is useful in the process of restoration. Sometimes their importance appears in the peak energy exchange, but this latter feature only appears if the countries involved are spaced in meridians so that they do not peak simultaneously, making the exchange difficult (unless the country has a large production that exceeds its maximum consumption)
