This paper proposes the Linear Swing Dynamicsbased Virtual Synchronous Generator (LSD-VSG) for HVDC systems. The aim is to define a new role and behavior for HVDC systems in their participation to AC system frequency support. This results in enhancing the frequency stability of HVDC connected-AC grids based on the LSD concept, whereas preserving a stable operation of HVDC system. Small signal stability and parametric sensitivity analysis have been performed to support the viability of the
