This study investigates the installation of multiple droop-controlled distributed generator (DG) sites in an Autonomous Microgrid (AMG) to mitigate power losses. The methodology employs a differential evolution algorithm integrated with a modified backward-forward sweep load flow method to optimise the DG sizing and positioning. Tested on an IEEE 33-bus AMG, the results show a significant reduction in power losses with multiple DG placements, highlighting the potential to improve microgrid performance.


Przedstawiono analizę umiejscowienia generatorów rozproszonych (DG) w izolowanej mikrosieci (AMG), z regulowanym statyzmem oraz z rozwiniętą strukturą hierarchiczną w celu redukcji strat mocy. Metoda wykorzystuje algorytm ewolucji różnicowej zintegrowany z modyfikowaną metodą rozpływu mocy w celu optymalizacji rozmiaru i pozycjonowania DG. Przetestowane na 33-węzłowej mikrosieci testowej IEEE wyniki ukazują znaczącą redukcję strat mocy dzięki optymalnym lokalizacjom DG, wskazują na potencjał poprawy wydajności pracy mikrosieci
