Applying A Revised Approach Of Fuzzy Cognitive Maps On A Hybrid Electrical Energy System, Ekavi Antoniou, Eleni S. Vergini, Peter P. Groumpos

International Journal of Business and Technology

Complex systems modeling is a rapidly developing research field which incorporates various scientific sectors from bio medicine and energy to economic and social sciences. However, as the systems’ complexity increases pure mathematical modeling techniques prove to be a rather laborious task which demands wasting many resources and in many occasions, could not lead to the desired system response. This realization led researchers turn their attention into the field of computational intelligence; Neural Networks and Fuzzy Logic etc. In this way scientists were able to provide a model of a system which is strongly characterized by fuzziness and uncertainties.

Improving Efficiency, Reduction Of Pollution And Co2 Emission From Power Plant Kosovo, Afrim Syla

UBT International Conference

In recent years, global warming has been a major issue due to continuous growth of greenhouse gas emissions from different sources. Earth’s atmosphere is composed of a variety of chemical compounds that act as greenhouse gases. Carbon dioxide (CO2) is of primary concern due to growing global emissions in recent history. Since the expansion of coal use during the industrial revolution and the expansion of petroleum use during the 20th century, CO2 emissions have risen steadily.

The major factor in Kosovo’s political, social, and economic life today is the development and social sustainability. The biggest challenge for Kosovo remains the …

Monitoring Of Air Quality In The Urban And Industrial Areas In Kosovo, Besa Veseli, Sami Gashi, Shkumbin Shala

UBT International Conference

Environmental pollution has a direct or indirect effect, and is mainly caused by human activity or environmental processes that have harmful effects in the environment and human life.In Kosovo the air pollution in Kosovo is quite evident in the industrial areas. The power plant of KEK (TCA and TCB), from the Cement Factory and ferronickel etc.

In the vast majority of cases, the pollution is caused by the emission of sulfur dioxide (SO2), azotes (NOx), ozone, lead and other heavy metals, such as carbon monoxide (CO), dust, PM10,PM2,5 and steamy organic components.

The aim of this inquiry is to study …

Economic Aspect Of The Electricity Production In Subsidiary Mpc Oslomej, Imer Zenku

UBT International Conference

The need to increase the production of electricity in the Subsidiary MPC Oslomej (Mining Power Complex-Oslomej), which operates as part of JSC ELEM (Macedonian Power Plants), 100% state owned company, represents a significant economic activity.

Therefore, the analysis in this paper focuses and aims at the economic aspect of the current electricity production, that is, the impact of the expenditures of the Subsidiary on the price of electricity produced by ELEM JSC, a price also regulated by the Energy Regulatory Commission of the Republic of Macedonia (ERC).

This shall draw attention to the necessity to timely prepare and adjust the …

Evaluation Of The Ereniku River Waters In The Locations Where The Lukac River Flows, Faton Maloku, Luan Daija, Xhelal Këpuska

UBT International Conference

The fate and transport of many anthropogenic pollutants have an impact not only on hydrological cycles, but also on physico-chemical processes.Water resource monitoring will assess the quality of water, identify its depreciation, and help policymakers make decisions that will preserve not only natural areas but also improve quality of life.Therefore the purpose of this paper is to evaluate the physical and chemical parameters of the locations where the river Lukac flows into the Erenik river. Erenik is a river in the western part of Kosovo.The water quality of the Ereniku river comes from anthropogenic activities, mainly from sewage discharges, from …

Evaluation Of Physical - Chemical Contaminants In Lumbardhi River In Prizren For The Period May - June 2017, Gashi Sami, Bajmaku Ymerr, Besar Veseli, Drini Petrit

UBT International Conference

This paper covers the monitoring of water pollution in the river basin from the source to the White Drin flow monitoring the river flow both in the rural and urban areas of water quality. The biggest problem in environmental protection is the quality of surface water. The results from the analysis of the study will serve to know the pollution from these physical-chemical parameters and at the same time to manage the eco-status in order to prevent negative trends and create a desirable balancing of so important the ecosystem as it is the system consist of Lumbardhi River, with biodiversity …

An Overview Of Zero Energy Buildings With An Emphasis On Energy Savings, Lazaros Aygeris, Peter P. Groumpos

UBT International Conference

The indiscriminate exploitation of the planet's energy sources has nowadays led to an uncontrolled form of climate change, with negative consequences for both humankind and the environment. In an effort to curb this situation, energy savings in both the building sector and other sectors of activity (industry, transport, etc.) is a primary objective and an indispensable component of any energy policy been planned today all around the world. As the building sector consumes 40% of the energy required at European level, the European Union (EU) has made considerable efforts to significantly reduce these consumption levels. In recent years, the European …

Smart Grid Operation: A Survey, Kozeta Sevrani, Romina Muka

UBT International Conference

Creation of Smart Grid meets the energy requirements of the 21stcentury in a high-tech manner with real time approach by providing asignificant improvement in power reliability and services, and integrating thelatest digital communications in the current power grid. This grid improves theability of consumers and utilities to monitor, control, and predict the use ofenergy. Up to the present time, Smart Grid has involved numerous researchersfrom different viewpoints. This paper provides an extensive literature review ofSmart Grid technologies and its characteristics. There are a lot of problems andchallenges in the field of Smart Grid. Therefore, this paper can help to find …

Using Of Hvdc Technology In Super Grids, Ines Bula, Valmira Hoxha, Edin Bula

UBT International Conference

This paper describes the HVDC system, its organization, as well as advantages over the AC system. Implementation of this system will help to make Europe sustainable energy independent which will require a renewable generation portfolio where much of this portfolio will be fueled by wind and will be developed offshore as it is presented in this paper. To deliver this energy to European consumers will require the development of a high capacity transmission system the so called Supergrid, which will be capable of delivering this energy to Europe's load centers. In this paper also is presented, a DC connection of …

Wind Turbine Technology Enables Sustainable Development Of Electricity In Kosovo, Vehebi Sofiu

UBT International Conference

The requirements of the EU directives for the renewable energy market, in particular wind turbines, enable sustainable development to meet the requirements for electricity generation. Global changes and environmental disasters resulting from industrial pollution do not allow a sustainable development of alternative natural resource exploitation. Balkan states and Kosovo are obliged to increase energy efficiency, to increase the discipline related to flow of fossil fuel emissions, which means less CO2 and greenhouse gases, and to advance the renewable energies by 20% up to 2020. Wind generation turbines are used to transform energy from a rotational mechanical action to generate electricity. …
