, distributed generators and loads that have connection points called busses. A bus in home circuit breaker panels is much smaller than those used on the grid, where busbar

s. Traditionally, these grid connections are unidirectional point to multipoint links. In distributed generation
grids, these connections are bidirectional, and the reverse flow can raise safety and reliability concerns. Features in smart grids are designed to manage these conditions.
A premises is generally said to have obtained grid connection when its service location becomes powered by a live connection to its service transformer.
A power station
is generally said to have achieved grid connection when it first supplies power outside of its own boundaries. However, a town is only said to have achieved grid connection when it is connected to several redundant
sources, generally involving long-distance transmission.
Grid (electricity)
An electrical grid is a vast, interconnected network for delivering electricity from suppliers to consumers. It consists of three main components: 1) generating plants that produce electricity from combustible fuels or non-combustible fuels ; 2) transmission lines that carry electricity from power...
