Abstract
U ovome radu ukratko su opisane različite literature koje se bave temom optimizacije primijenjene na aktivne distribucijske mreže koje sadrže distribuiranu proizvodnju. Dana je definicija aktivne distribucijske mreže, navedeni su utjecaji distribuirane proizvodnje na prilike u mreži te metode za njihovo ublažavanje. Predstavljeni su optimalni tokovi snaga kao temeljni optimizacijski problem u elektroenergetskim sustavima. U nastavku rada dan je primjer optimizacije niskonaponske distribucijske mreže s aktivnim kupcima. Dana je formulacija matematičkog modela optimizacijskog problema gdje pripadajuću funkciju cilja predstavlja minimizacija gubitaka snage. Detaljno je prikazano modeliranje mreže na temelju koje su odrađeni simulacijski slučajevi te su definirani parametri optimizacije. Kao rješenje za smanjenje negativnih utjecaja DP na mrežu, korištena je kombinacija metoda ograničenja proizvodnje iz FN sustava i upravljanja jalovom snagom iz FN pretvarača. Simulacije su provedene u programu pandapower. Analizirana je mreža u slučaju kada FN sustavi nisu u funkciji. Zatim su provedeni proračuni tokova snaga te optimalnih tokova snaga u slučajevima kada su FN sustavi u funkciji na svakom drugom kućanstvu te u slučaju kada su u funkciji na svakom kućanstvu. Na temelju dobivenih rezultata, izvedena su zaključna razmatranja.
Abstract (english)
In this thesis, various literature dealing with the topic of optimization applied to active distribution networks containing distributed generation are briefly described. The definition of an active distribution network is provided, the impacts of distributed generation on network conditions are listed, and methods for mitigating these impacts are discussed. Optimal power flows are presented as a fundamental optimization problem in power systems. Further in the paper, an example of optimizing a low-voltage distribution network with active customers is given. The formulation of the mathematical model for the optimization problem is described, with the objective function representing the power loss reduction. The network modeling is described, based on which simulation cases were performed and the optimization parameters were defined. As a solution to reduce the negative impacts of distributed generation on the network, a combination of two methods was used – active power curtailment and reactive power control through the photovoltaic inverters. Simulations were conducted using the pandapower program. The network was analyzed in the case where photovoltaic systems were not operational. Then, power flow calculations and optimal power flows were executed in scenarios where photovoltaic systems were operational in every other household and in the scenario where they were operational in every household. Based on the obtained results, concluding considerations were made.
