Predictive Direct Power Control of Three-Phase Grid-Connected Voltage-Sourced Inverters
摘要
Abstract
This paper investigates a novel direct power control,predictive direct power control （P-DPC）,for three-phase grid-connected voltage-sourced inverters（GC-VSI）.Different strategies to select voltage vectors and their duration time appropriately are addressed to eliminate the low-orders harmonic of currents,and obtain better dynamic and static performance.The P-DPC,which is implemented in the stationary reference frame directly,can obtain a fixed switch frequency instead of the shortcoming of variable switching frequency appears in conventional look-up table direct power control（LUT-DPC） and,meanwhile,it still maintains the fast transient feature of DPC.Furthermore,it requires no synchronous reference frame transformation and space vector pulse width modulation.The simulation and experimental investigation on LUT-DPC,vector control and P-DPC are carried out on a 2kVA GC-VSI.The results show the effectiveness of the proposed P-DPC strategy and its application potential on renewable energy industry.关键词
