Hysteresis current control technique for grid-connected PV systems using space vector modulation method
摘要
Abstract
A space vector modulation (SVM) based hysteresis current control technique for grid-connected photovoltaic (PV) system is studied in this paper. This technique adopts dual-hysteresis-loop to get error current signal. The inner loop confines output current, and the outer loop decides output reference voltage vector. This technique optimizes grid-connected PV inverter's output voltage according to current error signals, so as to lower down current error changing rate, which reduces switching frequency. This technique combines advantages of both SVM method and hysteresis control method, improves system response speed, and lower down equipment heat and energy loss, which shows a high quality performance.关键词
