Low　voltage　ride-through　(LVRT)　requires　wind　power　generation　systems　to　remain　continuous　operation　during　the　sudden　grid　voltage　sag　and　provide　reactive　power　support　for　power　grid.　To　enhance　the　LVRT　capability　of　wind　power　generation　systems　using　doubly-fed　induction　generators　(DFIGs),　this　paper　proposes　a　disturbance　attenuation　control　(DAC)　method　based　on　state-dependent　Riccati　equation　(SDRE)　technique.　The　DAC　objectives　are　as　follows:　the　rotor　side　converter　should　provide　required　reactive　power　support　for　power　grid　during　the　transient　period;　the　grid　side　converter　should　keep　the　DC-link　voltage　constant.　Based　on　the　above　control　objectives,　the　corresponding　DAC　problems　are　constructed,　and　the　feedback　control　laws　are　obtained　by　using　SDRE　technique.　The　influence　of　control　objectives,　control　effect　and　control　cost　are　fully　considered　in　the　design　of　weighing　matrices.　To　ensure　the　rotor　current　and　DC-link　voltage　are　within　the　safe　range　in　the　LVRT　process,　a　rotor　current　limiting　mechanism　is　proposed　and　a　protection　circuit　using　series　dynamic　resistor　is　adopted.　Compared　with　the　simulation　results　of　the　conventional　proportional-integral　(PI)　control,　the　PI　control　based　on　particle　swarm　optimization　(PSO),　the　sliding-mode　control,　and　the　exact　linearization　control,　the　proposed　control　strategy　has　better　transient　performance　and　can　effectively　improve　the　LVRT　capability　of　wind　power　generation　systems　using　DFIGs.　©　2020　Automation　of　Electric　Power　Systems　Press.
