Dual-mode　photovoltaic　power　system　should　be　capable　of　operating　in　grid-connected　(GC)　and　stand-alone　(SA)　modes　for　distributed　generation.　Under　different　working　modes,　the　optimal　parameters　of　inverter　output　filters　vary.　Inverters　commonly　operate　in　GC　mode,　and　thus,　a　small　capacitance　is　beneficial　to　the　GC　topology　for　achieving　a　reasonable　compromise.　A　predictive　current　control　scheme　is　proposed　to　control　the　grid　current　in　GC　mode　and　thereby　obtain　high-performance　power.　As　filter　are　not　optimal　under　SA　mode,　a　compound　control　strategy　consisting　of　predictive　current　control,　instantaneous　voltage　control,　and　repetitive　control　is　proposed　to　achieve　low　total　harmonic　distortion　and　improve　the　output　voltage　spectrum.　The　seamless　transfer　between　GC　mode　and　SA　mode　is　illustrated　in　detail.　Finally,　the　simulation　and　experimental　results　of　a　4　kVA　prototype　demonstrate　the　effectiveness　of　the　proposed　control　strategy.　©　2016　KIPE.
