This paper proposes a new remote voltage control approach based on the non-iterative holomorphic embedding load flow method (HELM). Unlike traditional power-flow-based methods, this method can guarantee the convergence to the stable upper branch solution if it exists and does not depend on an initial guess of the solution. Bus type modifications are set up for remote voltage control. A participation factor matrix is integrated into the HELM to distribute reactive power injections among multiple remote reactive power resources so that the approach can remotely control the voltage magnitudes of desired buses. The proposed approach is compared with a conventional Newton-Raphson (N-R) approach by study cases on the IEEE New England 39-bus system and the IEEE 118-bus system under different conditions. The results show that the proposed approach is superior to the N-R approach in terms of tractability and convergence performance.
