Distribution grids refer to the portion of an electricity grid that connects the high-voltage transmission system to end-users, such as homes, businesses, and industrial facilities. These grids are responsible for delivering electricity from power plants to consumers, managing the flow of electricity, and ensuring reliability and stability in the grid. Research in distribution grids focuses on improving the efficiency, reliability, and resilience of these systems through the integration of renewable energy sources, demand response technologies, smart grid technologies, and advanced communication and control systems. This research area also explores the impact of electric vehicles, energy storage technologies, and distributed energy resources on distribution grids, and seeks to develop new strategies and technologies to optimize grid operations and enhance grid security and sustainability.
