What is the function of power distribution systems?

The function of power distribution systems is primarily to deliver electricity from power plants to consumers. This process involves a network of substations, transformers, and distribution lines that transmit electrical energy efficiently over varying distances.

The distribution system ensures that electricity generated at power plants (which could be derived from various sources, including fossil fuels, nuclear, or renewable energy) is routed through the grid and ultimately reaches residential, commercial, and industrial users. The system is designed to operate at lower voltage levels compared to transmission systems, making it suitable for safe delivery to end users.

While other choices mention important aspects related to electricity generation, storage, and transmission stability, they do not pertain specifically to the direct function of power distribution systems as a means of delivering electricity. Thus, the correct answer highlights the primary role of these systems in ensuring that electricity flows from generation sources to consumers.
