Abstract: At present, the installed capacity of new energy power generation equipment shows a trend of rapid growth. A higher proportion of new energy generation will make the power grid show the characteristics of high impedance, low inertia, weak damping and low short circuit ratio. However, traditional double-fed wind power converter usually adopts current source control mode, which is difficult to adapt to the increasingly harsh operating environment of power grid. Therefore, this paper studies a voltage source control mode of double-fed wind power converter, compares its performance with current source converter control mode, and proposes a switching method between voltage source converter control mode and current source converter control mode in the case of high voltage ride-through and low voltage ride-through. Through real-time network voltage monitoring, the converter control modes of voltage source and current source can be smoothly switched. Simulation results show that the proposed control scheme has good steady-state and dynamic performance, and can adapt to the requirements of new energy grid-connection. more...

Abstract: This paper presents a disturbance-observer-based virtual synchronization control strategy for DG (distributed generation) clusters. The design process of inertia control structure of virtual synchronous generator is firstly adopted for DG clusters. Then the integrated small-signal virtual synchronization control characteristics is derived considering the DG output power fluctuation and load power fluctuation, which shows that system response needs further enhancement for expected dynamic recovery. To suppress the impact of external disturbances on system response, the extended disturbance-observer both for active and reactive power is proposed in this paper to estimate the external power disturbances and then enhance the robustness of the virtual synchronization control for DGs. The dynamic response analysis of the extended disturbance-observer for DG clusters is also conducted to demonstrate the anti-disturbance performance of the proposed control strategy. Theoretical stability analysis and simulations on PSCAD/EMTDC verify the validity and superiority of the proposed control strategy. more...
