Power transmission and distribution is one of the important infrastructure around the world providing an electrical energy for people and business across various industries. Growing urbanization and industrialization leads to an exponential increase in electricity consumption demand. Underdeveloped power infrastructure causes power losses and transmission lines overloads. The constantly growing number of renewable energy sources requires alternative methods of transporting energy from remote regions to developing city centers. Establishment of electric vehicle infrastructure, renewables integration and long distance transmission push the need for advanced power transmission and distribution technologies. High-voltage transmission systems, including high voltage direct current transmission (HVDC) and flexible altering current transmission system (FACTS), are being actively adopted to minimize the power transmission losses and to ensure grid stability and reliability. The combination of AC and highly controllable DC systems has been mainly used to withstand intermittent additional load on the grid and enable operation at high stability. Advanced grid infrastructure solves various power system control problems and accommodates the rise of renewables in the energy mix. This research service titled, “Technologies in Power Transmission and Distribution,” provides an overview of efficient and cost-effective methods for transmitting electric power from one location to another. This research study focuses on the latest achievements in the development of high-voltage transmission systems, including HVDC and FACTS. The disadvantages, key benefits, technology applications, benchmarking analysis of different power transmission technologies are described. Additionally, it presents the technology diagram illustrating the main power system components, challenges, drivers, market needs, and future prospects in development of advanced power transmission and distribution technolo
