In this paper, a three loop control strategy (TLCS) based on decoupled zero voltage switching angle (ZVSA) loop is proposed for a series-series (SS) compensated wireless power transmission (WPT) system. To realize constant current charging for EVs and ZVS operation of primary inverter, variable frequency and phase shift control strategy (VF-PSC) is adopted. However, the control variables that are...
Inverters in voltage control mode including droop control and virtual synchronous generator (VSG) are promising for interconnecting the renewable energy to the grid, which are both emulating the frequency and voltage regulating functions of synchronous generators through droop method. However, improper transient impact current and reactive power output are observed for inverters in voltage control...
A novel practical virtual synchronous generator control strategy considering the differences between inverters and real synchronous generators is proposed in this paper. The proposed control strategy improves the emulation method of damping power in swing equation, which does not need a PLL and in the meanwhile eliminates the effect on the droop coefficient caused by the traditional constant damping...
