  • Место и улога система даљинског грејања у стратешким плановима развоја енергетског сектора Републике Србије

    Dejan Ivezić, Marija Živković (2022)
    Системи даљинског грејања представљају врло битан елемент енергетског система Републике Србије. Инжењерски посматрано, ради се о системима који су концептуално осмишљени у другој половини ХХ века и чије функционисање почива на коришћењу фосилних горива. Трансформација ових система, у склопу енергетске транзиције читавог енергетског система Републике Србије, претпоставља, између осталог, значајније коришћење обновљивих извора енергије у производњи топлотне енергије, смањење губитака и повећање енергетске ефикасности производње и дистрибуције енергије, дигитализацију процеса, итд. У раду се укратко излаже тренутно стање система ...

  • A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia

    Boban Pavlović, Dejan Ivezić, Marija Živković (2021)
    When assessing the potential of renewable energy alternatives for electricity generation, it is necessary to implement a multi-perspective approach that includes economic, technical, environmental, and socio-political criteria. For the evaluation of criteria and alternatives, the Fuzzy Analytical Hierarchy Process (FAHP) method is applied. The obtained weights are formed according to the values of energy indicators and expert judgments. The use of a fuzzy numerical value scale for the assessment of expert judgments and energy indicators provides a more sensitive ...

  • Identification of the Best Available Renewable Energy Source for Electricity Production in Serbia

    Boban Pavlović, Dejan Ivezić, Marija Živković (2020)
    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 ...

  • Transition pathways of household heating in Serbia: Analysis based on an agent-based model

    Boban Pavlović, Dejan Ivezić, Marija Živković (2022)
    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 ...
