Its primary advantage lies in the relative ease of voltage transformation using transformers, which is crucial for distribution. AC systems are the backbone of most national and regional grids for interconnections over short to medium distances. Within AC, common EHV voltage levels include 345 kV, 400 kV, 500 kV, and 765 kV. Conversely, High Voltage Direct Current (HVDC) technology is specialized for specific applications where it offers superior advantages. HVDC is markedly more efficient for transmitting bulk power over very long distances, as it does not suffer from the same capacitive and inductive losses inherent in AC lines. It is also the preferred technology for interconnecting asynchronous AC grids (grids that are not synchronized in frequency), such as linking different countries or regions, and for long-distance submarine cable connections, like those for offshore wind farms. HVDC systems can be further categorized into Line Commutated Converters (LCC) and Voltage Source Converters (VSC), with VSC technology offering greater control and flexibility, making it ideal for connecting offshore wind and weak grids. The choice between AC and DC is a critical strategic decision based on distance, power capacity, cost, and technical requirements.

Application Insights
