As the penetration of renewable energy sources in the power system increases, the threat towards frequency stability is gradually expanding. To address this issue, the virtual synchronous machine (VSM) technology has emerged as a solution to provide a synthetic inertia to the grid. However, an improper setting of VSM parameters can adversely affect the grid support and may lead to a synchronization failure. Therefore, a design method to optimally tune damping parameters is discussed in this paper for current-referencing electrified synchronous machine (CURESYM), which is one of the VSM topologies. Because the proposed design method is based on an eigenvalue analysis, a linearized small-signal state-space model of CURESYM is derived at first. This state-space model is utilized to formulate a cost function, which can be a quantitative index to evaluate the influence of the damping parameters. The effectiveness of the proposed design method is finally demonstrated with simulation and experimental results.
