The CVS-VSG scheme is realised on type-4 WTGs based on the equations of motion of capacitor voltages. The type-4 WTGs are controlled as VSGs to emulate the inertial and primary frequency responses of conventional SGs. Active load sharing between Type-4 WTGs is achieved by a governor with capacitor voltage droop characteristics. Modal analysis was carried out on a test system with 73.58% wind power penetration. Simulation studies were undertaken to evaluate the performance of the CVS-VSG scheme on the test system subject to large disturbances. %@ 1751-8687 %T Capacitor voltage synchronising control-based VSG scheme for inertial and primary frequency responses of Type-4 WTGs %B IET Generation, Transmission & Distribution %D August 2018 %V 12 %N 14 %P 3461-3469 %I Institution of Engineering and Technology %U https://digital-library.theiet.org/;jsessionid=2fshse2k8e6cq.x-iet-live-01content/journals/10.1049/iet-gtd.2017.1602 %G EN
