Abstract

Brazil has great potential for the generation of photovoltaic solar energy and, currently, any consumer can generate their own energy and receive credits from the power distribution company. With the increase in the installed power capacity and the decentralization of the system, anti-islanding techniques become essential to disconnect the Distributed Generation inverters in the event of absence of the electrical grid, avoiding problems about safety, energy quality and reliability. This research project aims at the study, analysis and simulation of anti-islanding techniques, being "harmonic distortion monitoring" using Machine Learning, plus "Sandia Frequency Shift" and "Sandia Voltage Shift" with techniques fusion. A comparative analysis of the techniques will be carried out considering implementation difficulty, assertiveness, time to detection, DHT of the injected current and degree of disturbance in the grid, with codes in C++ and results presented in the final report.(AU)
