20.500.12556/DKUM-86304 Proportional-integral controllers performance of a grid-connected solar PV system with particle swarm optimization and Ziegler-Nichols tuning method This paper deals with photovoltaic (PV) power plant modeling and its integration into the medium-voltage distribution network. Apart from solar cells, a simulation model includes a boost converter, voltage-oriented controller and LCL filter. The main emphasis is given to the comparison of two optimization methods-particle swarm optimization (PSO) and the Ziegler-Nichols (ZN) tuning method, approaches that are used for the parameters of Proportional-Integral (PI) controllers determination. A PI controller is commonly used because of its performance, but it is limited in its effectiveness if there is a change in the parameters of the system. In our case, the aforementioned change is caused by switching the feeders of the distribution network from an open-loop to a closedloop arrangement. The simulation results have claimed the superiority of the PSO algorithm, while the classical ZN tuning method is acceptable in a limited area of operation. photovoltaic power plant optimization PI controllers distribution system fotovoltaika optimizacija regulator PI distribucijski sistem true false true MDPI Angleški jezik Slovenski jezik Znanstveno delo 2023-11-10 10:55:14 2023-11-10 11:15:27 2023-11-11 03:12:49 0000-00-00 00:00:00 2021 0 0 str. 1-15 št. 9, št. članka 2516 letn. 14 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-03-30 2021-04-24 2021-04-27 621.317:502.21:523.9 61414659 10.3390/en14092516 1996-1073 Proportional-integral_controllers_performance_Dezelak_2021.pdf Proportional-integral_controllers_performance_Dezelak_2021.pdf 1 60F6F1F326B0718ED4A005083E3AB2F6 08b3d11b1d73f232ac0c0453c3686dbe79d4bd6381989a33f0b3bc2f2bbce46b f49385c4-7fb1-11ee-b512-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174030 https://www.mdpi.com/1996-1073/14/9/2516 0 019b79b6-7fb2-11ee-b512-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174031 Fakulteta za energetiko Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
