Summary In this paper, a tuning approach for HVDC control technology based on virtual synchronous power (VSP) concept is developed and reflected in an extended multiarea automatic generation control (AGC) system including renewable energy sources (RES). A novel, nature‐inspired algorithm named adaptive mixed grey wolf (amixed GWO), which combines two improved versions of GWO, was recently proposed in order to effectively handle a problem with both discrete and continuous variables. This algorithm was first applied to optimize the VSP‐based controller parameters based on integral square error (ISE). The performance of the proposed algorithm has been compared with FMINCON's interior‐point algorithm to demonstrate its positive effects on the system stability. For better dynamic performances, a new optimization approach based on eigenvalues sensitivity analysis was proposed for the purpose of achieving optimal VSP control variables tuning for different power system structures. Simulation tests were performed to show the higher level of stability performance achieved by the proposed approach compared to the one based on ISE. Simulation results also revealed that the amixed GWO technique has better tuning capability in comparison with the other applied GWO versions.

“…The transmission power of the HVDC system can be changed rapidly according to the preformulated strategy or plan, including emergency DC power rise and drop. The conventional HVDC transmission system has 1.1 times long-term overload capacity and 1.5 times short-term overload capacity (generally 3 s) [14]. The limitation of minimum operating power should be considered in emergency DC power reduction.…”

“…Formula (16) indicates that the primary frequency regulation capability of the system is equivalent to that of the traditional power system. Formula (14) reflects the transient characteristics of the frequency response process and should satisfy the relevant provisions, and Δf max of the general large-scale system is no more than 0.2 Hz.…”

“…From the system perspective, the research on wind power participation in system frequency adjustment needs to be strengthened. The research of HVDC participating in system frequency adjustment mainly includes the frequency characteristics of the HVDC system under different control modes and the range of coordinated optimisation with primary frequency modulation parameters [13][14][15]. However, the potential of cooperated frequency modulation among HVDC, wind turbine and traditional frequency modulation measures remains to be tapped.…”
