Distributed generation optimization considering controllable and noncontrollable distributed sources in distribution network

Ovaj rad opisuje postupak optimizacije proizvodnje upravljivog distribuiranog izvora koji je priključen na srednje naponsku distributivnu mrežu na kojoj su instalirani upravljivi i neupravljivi distribuirani izvori. Za optimizaciju je korišten diferencijalni evolucijski algoritam i optimizacija je odrađena za zadane dnevne profile opterećenja i intenzitet energetskih izvora neupravljive distribuirane proizvodnje. Kao simulacijski alat korišten je OpenDSS računalni program, a za provedbu optimizacije korišteni su gotove biblioteke u Python okruženju. Simulacija je rađena za period od jednog dana u intervalima po sat vremena. Rezultati pokazuju kako su se gubici optimizacijom smanjili te se naponski profil sustava poboljšao.This paper describes the process of optimizing the production of controllable distributed power source that is connected to a medium voltage distribution network on which there are controllable and uncontrollable distributed power sources. Differential evolutionary algorithm was used for the optimization and optimization was performed for the given daily load profiles and the intensity of energy sources of the uncontrollable distributed production. OpenDSS computer program was used as simulation tool, and for the implementation of the optimization the ready-made libraries in the Python environment were used. The simulation was done for a period of one day in intervals of one hour. The results show that the optimization has reduced the losses and the systems voltage profile improved
