The　grid-connected　wind　turbine　(WT)　normally　requires　the　phase-lock　loop　(PLL)　to　ensure　the　integration　of　wind　energy.　However,　improper　settings　of　control　parameters　in　PLL　and　weak　AC　grid　condition　might　bring　about　negative　damping　for　the　system.　To　overcome　these,　this　paper　presents　a　design　of　DC　voltage　synchronization　control　(DVSC)　for　permanent　magnet　synchronous　generator　(PMSG)　based　WT　by　using　the　energy　function-based　method.　By　coupling　the　DC-link　voltage　with　converter　frequency,　the　grid　side　converter　(GSC)　of　the　PMSG　realizes　self-synchronization　without　the　aid　of　PLL.　The　inertia　response　and　damping　support　of　GSC　can　also　be　obtained　simultaneously　by　utilizing　the　dynamic　of　DC-link　voltage　without　jeopardizing　the　maximum　power　point　tracking　(MPPT)　property　of　PMSG.　To　demonstrate　the　effectiveness　of　the　proposed　control,　the　energy　function-based　analysis　of　PMSG　WT,　as　well　as　nonlinear　simulations　are　conducted　to　show　that　the　transient　stability　of　the　PMSG-based　WT　can　be　guaranteed　with　the　proposed　DVSC.　©　2021　IEEE.
