This paper investigates current and planned investments in new power plants in Bosnia and Herzegovina and impact of these investments on the energy sector, CO2 emission and internationally committed targets for electricity from renewable sources up to year 2020. Bosnia and Herzegovina possesses strong renewable energy potential, in particular hydro and biomass. However, the majority of energy production is conducted in outdated power plants and based on fossil fuels, resulting in environment pollution. New major investments The Stanari Thermal plant (300 MW) and the investment in Block 7 (450 MW) at the Thermal Plant Tuzla are again focused on fossil fuels. The power sector is also highly dependent on the hydrology as 54% of current capacities are based on large hydro power. In order to investigate how the energy system of Bosnia and Herzegovina will be affected by these investments and hydrology, the EnergyPLAN model was used. Based on the foreseen demand for year 2020 several power plants construction and hydrology scenarios have been modelled to cover a range of possibilities that may occur. This includes export orientation of Stanari plant, impact of wet, dry and average year, delayed construction of Tuzla Block 7, constrained construction of hydro power plants, and retirement of thermal units. It can be concluded that energy system can be significantly affected by delayed investments but in order to comply with renewables targets Bosnia and Herzegovina will need to explore the power production from other renewable energy sources as well.

Abstract The islands of Papua and Maluku are eastern Indonesia which consists of remote islands and villages. The Papua Islands consist of 3,749 islands divided into two provinces, namely Papua and West Papua, while the Maluku Islands are 1,735 islands into two provinces of Maluku and North Maluku, the number of inhabited islands in Papua and Maluku around 230 islands and around 100 newly electrified islands. The electrification ratio for Papua is 47.69%, West Papua is 89.94%, Maluku is 87.02% and North Maluku is 88.68%. The electrification ratio is still below the national average. Maluku Islands and Papua Indonesia has abundant renewable energy natural resources, namely hydro potential. The total hydro energy potential of Papua and Maluku is 808 MW. To overcome this shortage of electricity, it is necessary to develop a renewable energy generation system according to the potential of the area, namely hydro power. Energy generation technology that is environmentally friendly, efficient, effective, and reliable can be a solution for electrification in Papua and Maluku. Hydro power plants using vortex turbines, picohydro turbines and axial turbines for permanent magnet generators can be a solution to electrify areas or villages remote in Papua and Maluku.

Population growth and new forms of energy use have the effect that the energy demand grows year after year. The harmful influence of the use of fossil and nuclear fuels has influenced the intensive development of renewable energy sources (solar energy, small hydro power plants, wind energy, bio-renewable sources - biomass, geothermal energy). This paper gives an overview of the choice of design solution, technical parameters and the efficiency of small hydro power plants (SHPP) on small watercourses. Special attention in these considerations is dedicated to harmonization of selected solutions with natural resources and protection of ecosystems. In order to define the technical solution of one small HPP on a small watercourse, the following analyzes and studies need to be done: Hydrological study; Analysis of the available hydro potential; Pre-feasibility study of the chosen technical solution; Study on Environmental Impact Assessment; Analysis of the investment value of the elements of the system and the system as a whole; Analysis of annual fees and expenses. In analyzing the available hydro potential, it is necessary to examine in detail the influence of the minimum sustainable flow rate in the watercourse (biological minimum) both from the aspect of environmental protection and from the aspect of the techno-economic justification for SHPP construction. On the basis of the "cross-cutting" of the results of these analyzes, one can see the techno-economically justified solution for the construction of SHPP in line with the ecosystem. The goal of all previous analyzes is to select a technical solution that maximizes the use of hydro power potential and ensures optimum use of renewable energy sources, while paying special attention to ecology, environmental protection and sustainable development.

A b s t r a c t: The trend for achieving sustainable energy development, keeping the environment clean and utilization of renewable energy sources are imperative to the energy development in several countries. Through legislation and economical benefits, countries tend to encourage potential investors for building the technologies for energy production from renewable. In order to achieve the EU energy target to have 20% renewable in 2020, the technologies for producing electricity from renewable energy sources (RES) are used to cover the needs with more intensities. The most dominant renewable is the wind power plants(WPP) or wind parks, which are used to supply electricity to more power systems (EPS) and whose installed capacity in some European countries reaches thousands MW. This paper treats the issue of operational work of wind power in the power system of Macedonia. It is made of simulation work with wind power plants with total installed capacity of 150 MW with an annual production of 300 GWh. The considered power system of Macedonia is projected for the period of 2015 with an annual consumption of 10,000 GWh. The power plants considering operating in the simulated period are the existing thermal power units and hydro power plants together with the planned gas power plants and hydro power plants. The aim of this paper is to analyze the effects of the power system operation in case to have installed wind power plants, or what operation mode of thermal power plants (TPP) and hydro power plants (HPP) is most convenient when the system has a source of technology from the renewable with stochastically nature. This is especially important, because conventional power plants (TPP and HPP) operate and regulate the needs of consumption in the power system, but the wind power plants operate when the wind occurs within certain limits of  technical operating mode for wind turbines. Although wind is free renewable energy source, frequency of occurrence of wind with unpredictable nature and stochastically, has additional adverse impact in terms of power system operating mode. Certainly the impact of wind power on the overall the power system operation depends on power plants and configuration of the power system. In other words, the base load is covered from TPP fossil fuel or nuclear plants, and the dynamic nature of wind power can be incorporated in the power system depends on how much power plants for peak load are available in the system (storage reversible hydro or gas turbines), or how variable power can be accepted in the power system.

The European Union defined ambitious targets for the production of energy from renewable energy sources. Most European markets trade now high levels of variable renewable energy (VRE). Renewable generation increases the variability and uncertainty of the net-load (i.e., demand minus VRE). To a large extent, this variability and uncertainty can be compensated by hydroelectric power plants. Typically, hydro power producers (HPPs) consider the periods of time with low market prices (and normally low demand and/or high VRE production) to pump, and the periods with high market prices (and normally high demand and/or low VRE production) to produce energy. This article presents a model for hydro power plants and a study to analyse the hydro-wind balance in a real-world setting, namely a simplified version of the Portuguese power system, involving a significant penetration of hydro and wind power (more than 50%). The study is conducted with the help of the multi-agent system MATREM. The results confirm (and rebut) the typical behavior of hydroelectric power plants (to produce energy, to pump water or to stay idle).

Renewable energy is a solution for electricity generation for cleaner and green energy. The aim of this paper is to find the energy potential of India in terms of sources, per-capita energy consumption and the main potential consumers. Comparing consumption of fossil fuels and Renewable energy sources (RES) of India in 2019 and 2020 and finally to find whether there is any change in energy generation of two solar power plants in different geographical location of India with the help of independent t-test statistics. In this paper two statistical analysis are proposed. One is the statistical analysis of installed capacity, generation and consumption of fossil fuels and renewable energy in India. Other one is the statistical analysis of two solar power plants located at different geographical locations in India. From the statistical analysis it is found that, installed capacity of coal, RES and hydro is increased in 2020 as compared to 2019. Total demand in January 2020 is 2,77,140.33 MW whereas total installed capacity is 3,71,126 MW, this means that installed capacity is more but are not in running condition. From the statistical analysis of two independent solar power plants it is found that solar power plant-1 generates more energy but with high conversion loss hence poor efficiency.

Energy security and stability has become a major issue over the last few years in the whole world's economic and social development. Despite its high development and evolution of its approach to the issue of energy security, the European Union is also facing the problem of decreasing its role in reducing human impact on the climate. Energy is of essential importance for the development of any country, including Bosnia and Herzegovina. Without adequate policies in the energy sector bussines, industrial and economic progress is not possible either. However, regardless of how energy is important for the development, it is still only a mechanism for achieving an ultimate goal – sustainable economy, clean environment, high living standards, prosperity and population health. According to the official data, Bosnia and Herzegovina produces annually about 13.600 GWh (data from 2010), out of which 7.950 GWh in thermal power plants and 5.650 GWh in hydro power plants. Basic domestic energy sources in Bosnia and Herzegovina include coal and hydropower, while gas and oil are imported. This paper gives an overview of future of the European Union energy policy by 2020, together with the situation and outlooks for Bosnia and Herzegovina renewable energy sources: hydropower, wind power, solar energy, biomass and geothermal energy. The legislation of renewable sources in the Federation of BIH, as well as the European Union's legislative framework, are also presented.

Exergy Consumption

In developed countries like Austria the renewable energy potential might outpace the demand. This requires primary energy efficiency measures as well as an energy system design that enables the integration of variable renewable energy sources. Municipal energy systems, which supply customers with heat and electricity, will play an important role in this task. The cumulative exergy consumption methodology considers resource consumption from the raw material to the final product. It includes the exergetic expenses for imported energy as well as for building the energy infrastructure. In this paper, we determine the exergy optimal energy system design of an exemplary municipal energy system by using cumulative exergy consumption minimisation. The results of a case study show that well a linked electricity and heat system using heat pumps, combined heat power plants and battery and thermal storages is necessary. This enables an efficient supply and also provides the necessary flexibilities for integrating variable renewable energy sources.

There has been a rapid growth in construction activities during the last few decades owing to overall development in all facets of humanity. Due to technological advancements and ever increasing civilization, there is a persistent need of energy. Along with the conventional energy sources, the renewable energy sources have also significantly contributed to the rising energy needs. As a renewable source of energy, numerous small hydro-power plants (SHPPs) have been built up across the world in the recent past. Usually these SHPPs are being built and operated by the private developers complying with the government regulations. In order to assist a developer in selecting the most profitable and feasible SHPP for construction and subsequent operation, a method based on fuzzy axiomatic design principles is employed in this paper. The techno-commercial and socioeconomic criteria as considered for analyzing the feasibility of the candidate SHPPs are expressed qualitatively using trapezoidal fuzzy numbers. The performance of each SHPP is evaluated in terms of its total information content and the one with the least information content is selected to be the best venture for the required construction activity. The adopted methodology is found to have immense potential to the developers while selecting the most feasible project for construction.
