Human: What is a "smart grid" and how can it improve the power grid? Assistant: 
A smart grid is an advanced electricity network that uses information technology to monitor, control, and automate the transmission, distribution, and consumption of electrical energy. It aims to increase reliability, efficiency, and sustainability of the electric power system. Smart grids are designed to provide better service to customers by using data analytics, automation, and communication systems to optimize delivery of electricity. The improved capabilities of the smart grid enable utilities to reduce costs, increase customer satisfaction, and promote greater energy security.
