This paper considers high voltage direct current (HVDC) links for the primary frequency control of interconnected time-delay power systems with electric vehicles (EVs). Novel distributed control of HVDC links is proposed to minimize the differences in the frequency deviations between the connected power areas. A power system with EVs, HVDC links and multiple time delays is first presented. Then, we propose a new robust distributed HVDC controllers design method to stabilize the closed-loop system with a guaranteed H infinity performance. The design method can be flexibly extended to design static output feedback controllers of various structures to cater for different power system topologies. The performance and usefulness of our proposed controller design method is validated by extensive simulations.
