The final workshop of the DanuP-2-Gas project entitled: "Possibilities and potentials of using power-to-gas technology" was held in the hall of the Croatian Chamber of Commerce on 24th of November 2022. Project results and developed tools intended for different stakeholders in the Danube region were presented at the workshop by the Croatian project partners. The event was enriched by interesting guests. Mr. Vjekoslav Jukić from Ministry of Economy and Sustainable Development gave a presentation on the Croatian legislative framework related to hydrogen and potential financial tools and reported on the progress of the North Adriatic Hydrogen Valley established. Danica Maljković, PhD, (Indeloop d.o.o.), Ton ć i Panza, M.Sc. (Adria Wind Power d.o.o), Kre š imir I ž akovic, M.Sc. (Dilj d.o.o.), Dinko Đ urdevic, MBA (Hydrogen Europe) and Ante Sjauš, M.Ll (Zadar County) participated in an interesting panel discussion „Croatia's potential in hydrogen value chains“ moderated by Ivona Hulenić, M.Sc. (EIHP).
Within the DanuP2Gas project, in which FER with LARES participates as a project partner, two new tools for different stakeholders in the Danube region were developed. The aim of the tools is to stimulate interest in possible investment projects in power-to-gas hubs, as well as to reveal potential obstacles in their realization. The transnational atlas of renewable energy is an online tool in the form of a web geo-information system (GIS), shows various existing infrastructure elements for the planning of P2G hubs in Germany, the Czech Republic, Slovakia, Austria, Slovenia, Hungary, Croatia, Serbia, Romania and Bulgaria. The DanuP-2-Gas Optimization Tool is an off-line tool that provides an economically optimal unified proposal for structuring the conversion and storage processes in the hub and for their year-round operation profiles, for the selected point and infrastructure elements in the transnational atlas. Subsequent manual correction of all data downloaded from the atlas is possible, and it is also possible to enter data completely manually without using the atlas. Along with the optimal result, it provides an accompanying economic and technical analysis: the time and amount of consumption of input resources, the products of P2G hubs that are handed over to consumption chains, and the associated emissions. The Optimization Tool can be downloaded for free and the Atlas reached at the Danube Energy Platform . The DanuP-2-Gas Optimization Tool was developed by LARES members Filip Rukavina M.Sc., Antonio Karneluti M.Sc., and Marijo Šundrica PhD, mentored by DanuP-2-Gas local project leader and LARES head Prof. Mario Vašak.
The 103rd celebration of the Faculty Day of Electrical Engineering and Computing was held on Friday, November 25, 2022. The ceremony included a speech by the dean and other guests, with recognition and awards given to the best students. Also, as a part of the FER Faculty Day, a poster exhibition was set up presenting the projects implemented at FER. One of the projects presented was SmartCityLight project , one of the active LARES projects. The poster was introduced by Marina Gapit, mag.ing., a young researcher from the SCL team.
LARES team members, assoc. prof. Vinko Lešić and Hrvoje Novak PhD , presented at the Data Science Conference Europe 2022 , in Belgrade. Our team demonstrated how can machine learning modelling be combined with advanced model predictive control strategies to improve the way our cities operate. Results from buildings, water distribution systems, urban transport, city lighting and many more were showcased and joined together under a common term of smart cities. Interesting lectures, enticing discussions and an overall great conference atmosphere summarize the impressions.
On Saturday, November 5, 2022, elementary school students from the 5th to the 8th grade, attending the RADDAR mathematics and programming program visited our laboratory. During this visit, students learned about the problem of water supply and how it can be solved using artificial intelligence. LARES researchers who are working on this issue within the European scientific project REWAISE prepared a simulation to illustrate a small segment of the water supply system with a water tank for which they defined water consumption by individual end consumers. Through this simulation, they showed that with the use of knowledge in mathematics and physics, as well as programming and automation, the computer can determine the water pumping profile in the water reservoir, which can achieve significant water and electricity savings.
On October 21, 2022 the Ministry of Regional Development and EU Funds(MRRFEU) organized a study visit to the Croatian Parliament and to institutions which implement projects financed from European Union funds, for a group of about 80 students accompanied by teachers and principals of schools from Buzet, Dubrovnik, Duga Resa and Zadar. Their visit is a part of the activities of the project “In the School of Open Cohesion, ASOC”. We are proud that they chose our laboratory as an example of successfully implemented Interreg Transnational projects. As part of their visit to our laboratory, we prepared a presentation showing the results achieved by the implementation of the projects 3Smart and DanuP2Gas, financed through Danube Transnational Programme.
LARES research team published an article " Predictive control based assessment of building demand flexibility in fixed time windows " - Vašak, Mario; Banjac, Anita; Hure, Nikola; Novak, Hrvoje; Kovačević, Marko in Applied energy, a prestigious scientific journal. The paper introduces a simple strategy for modular building energy management with explicit demand response based on a three-level hierarchical model predictive control that engages the entire building in optimal operation and financially viable flexibility provision. It can be freely downloaded here until 30 December 2022.
