DISTRIBUTED GENERATION: SYNCHRONIZATION WITH THE GRID AND THE PROBLEM OF ISLANDING IN THE CONTEXT OF THE GROWING SUPPLY OF WIND AND SOLAR ENERGY IN BRAZIL

"Some renewable sources, such as wind and solar power, have been expanding rapidly in Brazil. The new type of distributed generation (DG) depends on electronic converters for connection to the distribution network, and on anti-islanding safety systems. Fouling occurs when the main generators on the grid go out of operation and the DG remains connected to the grid, causing risks to the unit, consumer loads and the grid. The objectives of this work are to implement the DG scheme in Matlab/simulink for a microgrid system, and to simulate islanding scenarios in situations of percentage variations in load consumption, in order to analyze DG voltage and frequency. Synchronization with the 230 V grid took less than 40 ms, with distortions of less than 2.5%. The stipulated meters delivered adequate voltage and frequency signals, with detection in just under 10 ms after the islanding."
