Abstract
This paper presents a control strategy based on the VSC emulating the behavior of synchronous machines. VSCs are the preferred electronic interfacing devices used for interfacing the distributed generators units or renewable generation units with the ac system in this paper. The regulation of the dc-link voltage helps in integration of these VSCs in the existing system in the presence of conventional synchronous machines. Two loops are designed each, to emulate the mechanical behavior of an SM which offers synchronization power to eliminate the need for a phase- locked- loop after initial converter synchronization, and damping power dynamics to damp power oscillations. This presents frequency dynamics similar to SMs, thus it introduces some inertia to the grid. Two different topologies for the dc-link voltage control are presented- direct dc-link voltage control and virtual torque control. These topologies are simulated using and the results of both the topologies are shown.
Keywords- Voltage Source Converters (VSC), Synchronous Machines (SM), Synchronous Generator (SG), dc-link voltage, Virtual torque, Virtual inertia.
