The expansion of renewable energy technologies, accompanied by an increasingly decentralized supply structure, raises many research questions regarding the structure, dimension, and impacts of the electricity supply network. In this context, information on renewable energy plants, particularly their spatial distribution and key parameters—e.g., installed capacity, total size, and required space—are more and more important for public decision makers and different scientific domains, such as energy system analysis and impact assessment. The dataset described in this paper covers the spatial distribution, installed capacity, and commissioning year of wind turbines, photovoltaic field systems, and bio- and river hydro power plants in Germany. Collected from different online sources and authorities, the data have been thoroughly cross-checked, cleaned, and merged to generate validated and complete datasets. The paper concludes with notes on the practical use of the dataset in an environmental impact monitoring framework and other potential research or policy settings.

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 However, the majority of energy production is conducted in outdated power plants and based on fossil fuels, resulting in environment pollution.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.

Renewable energy in Indonesia is not optimally developed. Most existing renewable energy power plants come from water and geothermal, but the utilized capacity is far away from significant. Lodagung mini-hydro power plant was built by The Public Corporation, Jasa Tirta I  with an installed capacity of 2x650 kW utilizing water from the Lodagung Irrigation Channel, Wlingi Dam to generate electricity in Blitar Regency, East Java. The plant has become the first to use Siphon technology in its operation. This study aims to analyse the potential power generated by Lodagung Mini-hydropower plant using primary and secondary data. The data processing was done by calculating the reliable discharge of the irrigation channel for three years since 2011 to 2013; calculating the water discharge in the siphon pipe; and calculating the estimated power generated by the plant. The findings indicate that the maximum discharge of the Lodagung irrigation channel is 13.78 m3/second, and the minimum discharge is 8.89 m3/second. The design discharge is 13.78 m3/second, and the maximum discharge in the siphon pipe is 3.96 m3/second/pipe. Based on the need, the expected power generated ranges from 16.48 kWh/day to 28.66 kWh/day.

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.

At present the power plant has a high dependence on energy sources such as diesel, natural gas and coal, while its energy source in nature is increasingly scarce, this situation encourages the development of renewable energy, one of which is in micro hydro power plants. This study aims to determine the effect of the width of the work triangle on the highest rpm produced. the fall of water on the pinwheel is set from the position angle of the nozzle 00, 150, 300, 450, 600, 750 and from the angle of the nozzle 00, 50, 100, 150, 200, 250, 300, 350 and 400 on the semicircular blade turbine, triangle blade turbine , and fin blade turbines. Semicircular turbine blade, working triangle area produces greater rpm at position of angle nozzle 00 and angle of nozzle 250 with area of work triangle 360,36 cm2, where the position produces 216 rpm at windmill rotation and 1626 rpm at generator rotation. When the nozzle position angle 150 and the nozzle angle 200 with the working triangle area 264.27 cm2, produce 221 rpm at the pinwheel rotation and 1711 rpm at the generator rotation. while at the nozzle position angle of 300 and the angle of the nozzle 100 the area of the triangle works 134.37 cm2 and produces 173 rpm at the spinning wheel and 1307 rpm at the generator rotation. on the triangle blade turbine and fin blade, the working triangle area does not affect the rpm produced.

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).
