The document reports the experimental validation of ADRC and PI controls, discretized and implemented in Control Hardware In the Loop (CHIL) simulations of a single-phase DAB converter to regulate the voltage of a node in a multiterminal and multilevel DC network in real-time. By placing the DAB in different points of the network, the controlled system is subjected to various disturbances, extending the simulation results from a single-terminal network to a three-terminal one.<\/p>\n","protected":false},"author":93,"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[652,1336],"targets":[1317],"rapporti_tipologie":[762],"class_list":["post-195908","rapporti","type-rapporti","status-publish","hentry","tag-active-networks","tag-dc-distribution","targets-research","rapporti_tipologie-report-en"],"acf":{"projects":{"ID":191050,"post_author":"464","post_date":"2024-07-10 16:51:19","post_date_gmt":"2024-07-10 14:51:19","post_content":"","post_title":"Architecture and management models of the electrical system and grids","post_excerpt":"The project aims to develop methodologies, software tools, prototypes and demonstrators to optimise electric transmission and distribution grids, as well as new architecture and system management models and new regulatory schemes that encourage the integration of renewable and non-programmable generation, self-generation, storage systems and aggregators, and that take into account electric penetration.","post_status":"publish","comment_status":"open","ping_status":"closed","post_password":"","post_name":"architecture-and-management-models-of-the-electrical-system-and-grids","to_ping":"","pinged":"","post_modified":"2024-08-21 12:10:45","post_modified_gmt":"2024-08-21 10:10:45","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.rse-web.it\/progetti\/architecture-and-management-models-of-the-electrical-system-and-grids\/","menu_order":0,"post_type":"progetti","post_mime_type":"","comment_count":"0","filter":"raw"},"order_posts":"","dont_show_search":false,"related_posts":false,"dont_show_hompage":false,"show_on_slider":false,"single_post_data":{"titolo_spot":"","post_content":"
This activity relates to the development of direct current (DC) systems in distribution networks. The applicability of the Active Disturbance Rejection Control (ADRC) method to the case study represented by the converters in a Medium Voltage Direct Current (MVDC) network for deriving Low Voltage Direct Current (LVDC) networks is typically addressed through computer simulations (off-line). In this report, ADRC control is compared with “traditional” strategies, specifically Proportional-Integral (PI) control.
\nThe performance of the two controls is analyzed through real-time Control Hardware In the Loop (CHIL) simulations of a Dual Active Bridge (DAB) converter connected to a multiterminal, multilevel direct current distribution network.
\nThis activity has therefore allowed for the extension of theoretical\/simulative considerations to physical implementations of the controllers, identifying ADRC control as a possible alternative to PI control for a power system connected to an MVDC network.
\nThe report introduces the discretization of continuous algorithms (ADRC and PI) necessary for implementation in a digital control system. The steps for the realization and validation of the CHIL control system setup and the real-time simulation environment used for the tests are described in detail. The methodology employed involves comparing the real-time results with the same reference implementations in off-line simulation environments. Following the presentation of the real-time implementation of the tri-terminal MVDC network, the CHIL simulation results are shown; the DAB converter is driven by an external control board where both controls have been implemented: the digital ADRC control is finally compared with the PI control.<\/p>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":173421,"id":173421,"title":"21009173","filename":"21009173.pdf","filesize":2510197,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2022\/11\/21009173.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/risultati-della-verifica-delle-prestazioni-di-un-controllo-active-disturbance-rejection-control-adrc-mediante-simulazioni-di-tipo-control-hardware-in-the-loop-chil\/attachment\/21009173\/","alt":"","author":"93","description":"","caption":"","name":"21009173","status":"inherit","uploaded_to":173420,"date":"2022-11-11 15:47:20","modified":"2022-11-11 15:47:20","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2021-12-31","autori":"A.
