 AC electric power can be smoothly exchanged between these regions if it is first converted to DC (direct current), transmitted over high voltage DC transmission lines (up to one million volts) and then reconverted to AC at a frequency that is synchronous with that of the receiving region. Another way for different regions to exchange electric power is by means of variable frequency transformers. AC electric power can be smoothly exchanged between these regions if it is first converted to DC (direct current), transmitted over high voltage DC transmission lines (up to one million volts) and then reconverted to AC at a frequency that is synchronous with that of the receiving region.

-One additional technique to maintain power grid reliability and frequency stability is by introducing so-called demand side management. The idea is for the power company to control devices like hot water heaters and cold water refrigeration used for air-conditioning in large buildings. Domestic hot water need not be produced during peak demand hours. The same applies to cold water refrigeration used for air conditioning. Thanks to computers and Internet communications the power grid could turn these devices on or off depending on electric power availability.+One additional technique to maintain power grid reliability and frequency stability is by introducing so-called ​//demand side management//.

 Another important aspect of electric power grids is legislation governing the transmission and distribution of electric power from utilities to customers. In the US the Energy Policy Act of 1992 was passed and it required owners of high power transmission lines to permit access to electric power generation firms. The Energy Policy Act of 2005 introduced measures to encourage the production of renewable electric power. Another important aspect of electric power grids is legislation governing the transmission and distribution of electric power from utilities to customers.
