Massive penetration of nonsynchronous units with power electronics devices in the future grid could diminish the rotational inertia of a power system and inevitably jeopardize the frequency stability. Several adaptations are made accordingly in the power system to provide a short-term inertial support. In this paper, synchronous power concept is used for inertia emulation (IE) in high voltage direct current (HVdc) transmission links for frequency control. However, the energy reserves capacity such as direct current (dc) link capacitances or distributed generations for IE are limited and therefore required additional energy storage. This paper considered mobile electric vehicles (EVs) network as an energy storage and their charging/discharging is done by balance state-of-charge (SOC) holder technique taking into consideration future driving demand of EV owners using battery SOC controller. Cooperative contributions from HVdc links and EVs during perturbation exceptionally damp the oscillation and peak deviation in grid frequency as well as in tie-line power. To validate the efficacy of proposed framework, numerous time domain simulation results are presented.
