Smart Grid vs. Traditional Electricity Grids

Electricity grids are intricate networks designed to transport electricity from power plants to end-users such as businesses and homes. In the past, proximity to power sources was necessary for factories and businesses to access electricity. The development of power grid systems revolutionized this by enabling electricity to be distributed over long distances.

At the core of electricity grids are transmission lines that carry energy at high voltages to minimize energy loss. These lines connect to a distribution network, which distributes electricity to end-users. Substations play a crucial role in this process by adjusting the high voltage of transmission lines to the lower voltage suitable for distribution and consumption.

A smart grid functions similarly to a traditional energy grid but incorporates advanced communication capabilities between electricity suppliers and users. Utilizing sensing, monitoring technology, and data transfer across the grid, a smart grid enhances versatility and reliability through various smart technologies.
