In recent years, the great progress has been made in the development of offshore wind power in Jiangsu. The scale of offshore wind power in operation has ranked the first in China, and it is expected that the scale will reach 12870MW in the end of the "14th Five-Year Plan". With the explosion and significant growth of offshore wind power, greater challenges in terms of wind power absorption and system safety will be induced in Jiangsu power system. Simultaneously, the offshore distances of wind power exploitation are getting farther and farther. For some of the approved offshore wind power projects, they will utilize the flexible direct-current (DC) transmission technology to satisfy the demands of long geographical distances. With the widespread application of flexible DC transmission technology in planned offshore wind power projects, the controllability of wind power transmission systems can be improved, but there are also new risks are introduced, such as providing short-circuit currents to the transmission system, sub/super-synchronous oscillations induced from control systems of power electronic equipment and integrated power systems. Considering the development scale of offshore wind power, operation modes and structure characteristics in Jiangsu during "14th Five-Year Plan", influences of large-scale offshore wind turbines integrated to the transmission power system are discussed, through short-circuit currents induced, voltage stability, sub/super-synchronous oscillations. Corresponding improvement measures are put forward.
