Power System Stabilization Control by HVDC with SMES Using Virtual Synchronous Generator

摘要

This paper describes power system stabilization with a VSG (virtual synchronous generator) control scheme by using VSC (voltage source converter) type HVDC (high-voltage DC transmission) with SMES (superconducting magnetic energy storage). Power system stabilization schemes that prevent instability due to the disturbance in grids that are connected to renewable power sources were studied. This paper further discusses the effect of SMES connected to the DC link of the VSC-HVDC system for the compensation of power fluctuation caused by distributed generators in one AC newtork of HVDC for eliminating the influence on the network on the other side to which the HVDC is connected. Simulations using PSCAD/EMTDC were carried out to evaluate the performance of the applied control system.
