Abstract –This case study explores the use of both HVAC (High Voltage Alternating Current) and HVDC (High Voltage Direct Current) transmission methods in the Nordic region's power grid. The region has a unique energy mix with a significant portion of their electricity generated from renewable sources such as hydropower, wind power, and solar power, and a high demand for electricity due to their cold climate. The power grid in the Nordic region is interconnected and operates as a synchronous grid, with an extensive network of HVAC transmission lines that connect various power plants and population centers. However, HVDC transmission is also used for longer distances, as it is more efficient than HVAC and incurs lower transmission losses. The successful use of a mix of renewable energy sources, an interconnected grid, and efficient transmission methods has allowed for a reliable and sustainable energy supply in the Nordic region.
