تجزیه و تحلیل روش های فعال تشخیص جزیره ای شدن برای میکرو اینورتر متصل به شبکه برای پردازش انرژی های تجدید پذیر

This paper presents the analysis and comparison of the main active techniques for islanding detection used in grid-connected microinverters for power processing of renewable energy sources. These techniques can be classified into two classes: techniques introducing positive feedback in the control of the inverter and techniques based on harmonics injection. Accurate PSIMTM simulations have been carried out in order to perform a comparative analysis of the techniques under study and to establish their advantages and disadvantages according to IEEE standards.
