The increased demand for renewable energy generation requires the higher flexibility of transmission systems. This requirement together with technical progress in high‐voltage DC technology has resulted in the ambition to build large‐scale multi‐terminal DC grids. To achieve this goal, vendor interoperability is considered a key element. Standards exist for AC systems, but not for DC systems. This work discusses and evaluates the suitability of AC standards for DC systems. As a result, a different view on substation architecture is developed and two communication protocols are suggested for further investigation in this context.
