In this paper, strategies for a holistic integration of multiple HVDC links into existing power systems are presented. High Voltage Direct Current (HVDC) links can support the operation of AC grids on different timescales. Contrary to AC transmission lines, the power flow on HVDC links can be freely controlled. Due to their ability of rapidly controlling the power transmitted, they can help to stabilize the dynamic system response of interconnected power systems, e.g. providing fast frequency response. Moreover, they can be an important tool in controlling and in optimizing the operation of interconnected power system. In this paper, different strategies are presented, then their benefits and potential challenges are discussed.
