Maintaining a reliable and efficient power grid is critical during the energy transition. High-voltage direct current (HVDC) and flexible AC transmission systems (FACTS) are two technologies that help keep the lights on during our journey towards a decarbonized grid. Renewable energy sources become increasingly prevalent, but they are often located in remote areas far from population centers, where energy demand is high. HVDC technology enables the transmission of large amounts of electricity over long distances, allowing renewable energy to be efficiently integrated into the grid. FACTS technology, on the other hand, is designed to improve the stability and control of AC power grids. Renewable energy sources, like wind and solar, are inherently variable, which can create instability in the grid. FACTS help to mitigate these stability issues by improving voltage and power flow control, reducing the risk of blackouts and other power disruptions.
