Identification of the Best Available Renewable Energy Source for Electricity Production in Serbia
Around 2/3 of electricity production in Serbia originates from coal-fired thermal power plants. The most significant domestic coal deposits are lignite deposits, a type of low -quality coal that causes negative health, climate and environmental impacts during the combustion. To reduce those negative impacts on domestic electricity production and to promote environmental awareness, the Serbian Energy Sector Development Strategy and the National Action Plan for Use of Renewable Energy Sources indicate the plan for increasing the share of ...Strategija obnovljive energije, Održiva energija, Proizvodnja električne energije, Solarna energija, Biomasa, Hidroenergije, Energija vetra... in Serbia Boban Pavlović, Dejan Ivezić, Marija Živković Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] Identification of the Best Available Renewable Energy Source for Electricity Production in Serbia | Boban Pavlović, Dejan Ivezić, Marija Živković | Conference ...Boban Pavlović, Dejan Ivezić, Marija Živković.

Life Cycle Assessment of Individual Wood Biomass Heating Systems in Households
The use of solid fuels (wood biomass and coal) for heating of households continues to be common practice within European countries. Solid fuel combustion in households contributes more than 46% to total emissions of fine particulate matter. In this study, a life-cycle assessment (LCA) of firewood-based and pellet-based heating systems is performed. These two systems represent two different types of individual wood biomass heating systems. In the case of the firewood-based heating systems, it is analyzed a typical stove ......

Business Models for Small-scale Biomass Projects Development
Biomass is recognized as the most promising renewable energy source in Serbia. The share of biomass in Serbian final energy consumption is over 10%, but mostly related to traditional use in stoves and ovens. One of the main obstacles for wider implementation of contemporary biomass facilities is the inexperience of consumers and stakeholders in the implementation of “innovative” business models, especially in the cases of small-scale projects. In this paper, three different business models (public utility company, energy cooperative ......

Challenges of Energy Transition in the Individual Heating Sector
U radu su prikazani rezultati istraživanja i ankete koja je sprovedena 2020. godine u domaćinstvima sa individualnim sistemima grejanja u Srbiji. Cilj ankete je bio da se sagleda stanje individualnih sistema grejanja, ali i stavovi vlasnika sistema vezano za energetsku tranziciju. Rezultati ukazuju na zastarelost sistema grejanja, nisku efikasnost, nedovoljna ulaganja u primenu mera energetske efikasnosti i nedostatak finansijskih sredstava za ulaganje u održivo grejanje. Osnovni prioriteti kod izbora načina grejanja jesu troškovi kupovine sistema i troškovi energenta, dok ...Boban Pavlović, Dejan Ivezić, Marija Živković.

Agent-based modeling as a support to an expert-based approach: Exploring individual heating systems transition
Expert-based energy scenarios are mainly developed following assumptions of experts and, in most cases, a limited number of stakeholders. Such an approach will provide satisfactory results in centrally managed energy sectors where further decisions could be envisaged relatively precisely (electricity production/distribution, district heating systems, etc.). The same approach will provide more uncertain outcomes of future energy structure in the household sector, where decisions related to consumption, selection of energy source, or application of specific technology are made by numerous ...Energetska tranzicija, Grejanje domaćinstava, Individualni sistemi grejanja, Energetsko planiranje, Integrisano energetsko planiranje, ABM, LEAP, SrbijaBoban Pavlović, Marija Živković, Dejan Ivezić.

Transition pathways of household heating in Serbia: Analysis based on an agent-based model
To explore pathways of the energy transition of household heating, an agent-based simulation model was developed for the case of the Serbian household sector. The model is focused on individual entities (households) with the objective to explore the effects of policy instruments on energy transition in households with individual heating systems. Empirically collected survey data were used as input for households’ attitudes towards sustainable heating. Simulations showed that the proposed instruments would lead to higher heating efficiency and less ...energetska tranzicija, modeliranje bazirano na agentima, sistemi grejanja, sektor domaćinstva, obnovljivi izvori energije, emisija CO2Boban Pavlović, Dejan Ivezić, Marija Živković.

Integrated energy planning approach for accelerating energy transition of households
The success of energy transition planning depends on several influential and variable factors that need to be considered and tracked in modeling to support policymakers. Expert-based energy models are mainly developed following the assumptions of experts and, in most cases, a limited number of stakeholders. This top-down modeling approach will provide satisfactory results in centrally managed energy sectors (electricity generation and distribution, district heating, etc.), where further decisions could be projected relatively precisely. However, the same approach will not ...Energetsko planiranje, Integrisano energetsko modeliranje, Energetska tranzicija, Domaćinstva, Individualno grejanje, LEAPBoban Pavlović, Marija Živković, Dejan Ivezić.
