Abstract
U magistarskom radu pod nazivom "Pogonsko optimiranje razdjelnih mreža genetskim algoritmom" prikazuje se nova metoda za rekonfiguaciju razdjelnih mreža. Razvijena je i aplikacija u svrhu provjere razvijenog genetskog algoritma. Pogonsko optimiranje provodi se u svrhu smanjenja toplinskih gubitaka, povećanja raspoloživosti mreže i bolje raspodjele opterećenja uz poštivanje topoloških i pogonskih ograničenja. Kvaliteta nekog uklopnog stanja ocjenjuje se proračunom struja i padova napona, te proračunom raspoloživosti razdjelne mreže. Odabrana optimizacijska metoda je eliminacijski genetski algoritam s permutacijskim kodiranjem. Za stvaranje početnih rješenja razvijena su dva algoritma koja kreću od uklopnice "u dubinu" i "u širinu". Za operator križanja odabrano je ER križanje (eng. edge recombination). Razvijen je algoritam mutacije kojem se zadržava radijalna struktura mreže. Provjerom razvijenog genetskog algoritma na konkretnim razdjelnim mrežama potvrdila se njegova učinkovitost u smanjenju toplinskih gubitaka od 17% do 28%, povećanje raspoloživosti razdjelne mreže na četvrtoj decimali, te mogućnost rasterećenja preopterećenih dijelova mreže.
Abstract (english)
The master thesis “Distribution power network reconfiguration using genetic algorithm” proposes a new method for power network reconfiguration accounting constraints. An application for testing the proposed method is also developed. Reconfiguration of power distribution network is used to reduce Joule losses of power network, to enhance network reliability and to achieve better load balance of the system’s feeders while satisfying constraints. Load flow (calculation of currents and voltage drops) is used to evaluate quality of a particular network configuration. Proposed optimization method is an eliminating genetic algorithm with permutation coding. For evolving initial solutions (population) two algorithms are developed: "in depth" and "in breadth". Edge recombination operator constructs an offspring that inherits as much information as possible from the parent structures and is therefore chosen. Developed mutation algorithm does not violate the radial network. The proposed genetic algorithm has been tested on real distribution networks. Joule losses have been reduced from 17 % to 28 % and reliability has been enhanced at fourth decimal.
