What is meant by a distribution network in an electrical utility system?

A distribution network in an electrical utility system refers specifically to the portion of the system that is responsible for delivering electricity to end users, such as residential, commercial, and industrial consumers. This segment of the utility infrastructure takes the high-voltage electricity generated at power plants and steps it down to a lower voltage suitable for use and ultimately distributes it to the customers.

The distribution network includes components like transformers, substations, and power lines that are designed to ensure that electricity is delivered safely, efficiently, and reliably. This is a critical function in the overall power system, as it connects the generation of electricity to the actual consumption by users.

Options referring to generation systems, collections of renewable sources, or voltage regulation focus on different aspects of the electricity supply chain. While these elements are important for the functionality and management of the grid overall, they do not encapsulate the specific role that a distribution network plays in the delivery of electricity to the end users. Therefore, the correct definition is specifically associated with delivering electricity rather than generating or regulating it.
