Abstract:
The power sector in Uganda has increased steadily, focusing majorly on rural electrification to increase the proportion of the rural population accessing electricity using grid extension and isolated mini-grid approaches. Hydropower mini-grids implemented in rural communities have issues regarding system failures leading to shutdowns and load shedding. A study on an existing isolated hydropower mini-grid was made to find the possible causes. A review of published articles and reports, and an analysis of enrollment patterns, energy sales, and load demand was carried out. A field survey with a guided questionnaire to collect information about real energy demand data was carried out. The performance of the system was accomplished through simulation using HOMER pro × 64 software. The findings from the study show a reduction in customer enrollment, a reduction in energy sales, and a reasonable number of system shutdowns. Hybridization of the existing hydropower was modeled with different options. The hybrid system proposed indicates that, when implemented, it would reduce fuel consumption from 222 to 23.2 L/day and emissions from 82.5 to 8.3 kg/year on average and increases system reliability. Simulated values of NPC, LCOE, and operating costs are appreciable. Despite mini-grid shortfalls, there is notably improved livelihood due to improved social and economic services.

Abstract:
Nowadays; Ethiopia is one of the countries which is under developing and one of the strategies to be used to develop the country is to explore and develop the sector of energy in Ethiopia. Our country Ethiopia needs to develop the rural electrification sectors in order to provide illumination to the population living in those rural remote areas for rapid development in different sectors like schools; health centers; business centers and administrative officers. Hence the current energy regime in Ethiopia, that is heavily reliant on the burning of biomass, has had major implications for the environment. There is a fast depletion of renewable sources that was used in the past for the generation of electricity and the difficulty in reachability of the grid supply to the remote villages was a big challenge faced. The best possible remedial measure in this scenario is to make use of the natural resources available to generate electricity. In an endeavourance towards this end, the paper has been formulated for the electrification of six selected remote Kebeles in Bambasi woreda. This kebeles are kinds of locality in which there are a tribal settlement of about 600 families each that do not have privilege of electrical energy supply. The present work focus on the feasibility studies carried out at the site for the assessment of mini hydro power plant potential of the site. The results of the study reveal that there is a huge potential at the site to develop a mini hydro power plant which would meet the energy demand of the tribal settlement and thereby improving their living condition. But the river is intermittent so that it is recommended to construct dam for the purpose of storage of water.

Abstract:
The use of the energy of small watercourses with the help of small hydropower plants is one of the promising directions for the development of renewable energy. This article presents the designs of two different hydraulic engines, each of which has its own advantage. Therefore, the task of calculating the real parameters of the design of a mini-hydropower plant based on Lenyov hydrobelt has been solved. Theoretical calculations were validated numerically by the finite volume method and computational fluid dynamics modeling; both methods gave similar results. According to the results of calculations, this design based on the Lenyov hydrobelt with the capacity of 16 kW is advisable to place in a river with a flow velocity of at least 4.5 m/s. The article also presents an alternative type of developed mini-hydropower plant, -a volume-sectional hydraulic engine. The proposed rotary-type positive displacement hydraulic engine can operate at low pressure on a flat surface. The advantage of the hydraulic engine is the sectional operation of several working chambers. It was established that a high water velocity and a large volume of passing water was not required. The total force acting in the hydraulic engine is 5430.19 N. Due to the use of conical inlet channels, the water flow velocity was increased and the water flow became directional. The frequency of rotation of the hydraulic engine shaft at a river flow velocity of 4 m/s was 60.43 rpm. The received power in these modes was 22.25 kW.

Abstract:
The presented paper deals with the evaluation of hydropower potential in a selected section of the Torysa river in the eastern part of the Slovak Republic. This part of the country was chosen based on the existence of a significant risk of increasing energy poverty in local marginalized communities. Small hydropower plants in the form of mini and micro installations are an ecological and economical way to secure electricity and suppress indicators of energy poverty. The essential part of work focuses on the quantification of the gross (theoretical), technical, and economic hydropower potential of the Torysa river using elevation data obtained by GIS tools and hydrological data provided by The Slovak Hydrometeorological Institute. The next step identified concrete locations with a suitable head and volumetric flow rate. In the last part, the assessed section of the Torysa river was analyzed in terms of geographical collisions with NATURA 2000 areas, historical heritage elements in the country, and natural water bodies without hydropower potential (i.e., lakes, ponds, etc.). The resulting technical hydropower potential of selected part of Torysa river is 5425 kW and the economic potential is 1533 kW.

Abstract:
UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. Mozambique is one of the poorest countries on earth but has abundant supply of energy resources. The electrification rate, however, has been slow. Rural electrification is hampered by lack of basic infrastructure, institutional barriers, and low ability and willingness to pay for energy services. Thus, there is a general gap between electricity supply and demand. In view of this, the present paper investigates supply and demand of electricity for a typical rural case study area in Mozambique. We suggest a nexus approach to improve water, energy, and food security initiated at a local level. Households in the investigated case study area can be connected to a mini-grid hydropower system that allows for energy production to 80–200 households. To increase the economic profitability of the mini-grid hydropower system we suggest including small-scale industry. For the studied rural village, this would be constituted by a small-scale factory for milling of corn and other cereals. Electricity produced can thus be used for food processing but also for pumping water supply to households for domestic use and small-scale irrigated farming lots. The results indicate that the villagers have a real payment capacity of between 8 and 19 USD per MWh of generated hydropower. Benefits of rural electrification are direct. It contributes to improved living conditions for households and provides better nexus security and sustainable development within healthcare, education, and small-scale business development.

Regarding the acceleration of renewable energy diffusion in Indonesia as well as achieving the national energy mix target, renewable energy map is essential to provide useful information to build renewable energy system. This work aims at updating the renewable energy potential map, i.e. hydro and solar energy potential, with a revised model based on the global climate data. The renewable energy map is intended to assist the design off-grid system by hydropower plant or photovoltaic system, particularly for rural electrification. Specifically, the hydro energy map enables the stakeholders to determine the suitable on-site hydro energy technology (from pico-hydro, micro-hydro, mini-hydro to large hydropower plant). Meanwhile, the solar energy map depicts not only seasonal solar energy potential but also estimated energy output from photovoltaic system.

Abstract:
Despite the clear advantages of mini hydropower technology to provide energy access in remote areas of developing countries, the lack of resources and technical training in these contexts usually lead to suboptimal installations that do not exploit the full potential of the environment. To address this drawback, the present work proposes a novel method to optimize the design of mini-hydropower plants with a robust and efficient formulation. The approach does not involve typical 2D simplifications of the terrain penstock layout. On the contrary, the problem is formulated considering arbitrary three-dimensional terrain profiles and realistic penstock layouts taking into account the bending effect. To this end, the plant layout is modeled on a continuous basis through the cubic Hermite interpolation of a set of key points, and the optimization problem is addressed using a genetic algorithm with tailored generation, mutation and crossover operators, especially designed to improve both the exploration and intensification. The approach is successfully applied to a real-case scenario with real topographic data, demonstrating its capability of providing optimal solutions while dealing with arbitrary terrain topography. Finally, a comparison with a previous discrete approach demonstrated that this algorithm can lead to a noticeable cost reduction for the problem studied.

Abstract:
ABSTRACT The study of hydropower potential focuses on hydropower development in Sumatra (4,408 MW), Java (4,595 MW), and Sulawesi (3,240 MW) is in line with the actual development of the hydropower industry. These three islands cover 95% of the viable hydropower potential. Meanwhile, the potential of PLTMH is 770 MW and about 30% has been developed. Most of the Microhydro (<1 MW) and Mini hydro (1-10 MW) are targeting rural electrification with the greatest potential in Papua and Sumatra. Therefore, in the concept of optimizing water use and aligning Water Food Energy Nexus, apart from modernizing irrigation, it is also necessary to develop the use of PLTMH in irrigation networks to generate electricity through a Micro Hydro Power Plant (PLTMH). In practice, the use of irrigation networks for the development of PLTMH electrical energy does not interfere with the flow of irrigation water used to serve the needs of the farming community because the MHP technology used as a power plant only utilizes irrigation water flow with a certain volume, both in the waterfall and the aspect of its flow rate. To find out the completeness of the readiness for the utilization of irrigation networks for MHP, it is necessary to conduct an initial assessment of the preparation process has been carried out. One of the assessment methods that can be used for the construction of MHP are to use a standard sustainable hydropower assessment protocol known as the Hydropower Sustainable Assessment Protocol (HSAP). Key words: power plant, micro-hydro, irrigation network, assessment protocol, HSAP ABSTRAK Studi tentang potensi tenaga air menempatkan fokus pada pengembangan tenaga air di Sumatera (4.408 MW), Jawa (4.595 MW), dan Sulawesi (3.240 MW), yang sejalan dengan perkembangan aktual industri tenaga air. Ketiga pulau ini mencakup 95% dari potensi PLTA yang layak. Sementara potensi PLTMH adalah 770 MW dan sekitar 30% sudah dikembangkan. Sebagian besar Mikrohidro (<1 MW) dan Mini hidro (1-10 MW) menargetkan elektrifikasi pedesaan dengan potensi terbesar di Papua dan Sumatera. Oleh karena itu, dalam konsep optimalisasi pemanfaatan air dan penyelarasan Water Food Energy Nexus, selain modernisasi irigasi, juga perlu dikembangkan pemanfaatan PLTMH pada jaringan irigasi sehingga menghasilkan listrik melalui Pembangkit Listrik Tenaga Mikro Hidro (PLTMH). Pemanfaatan jaringan irigasi untuk pengembangan energi listrik PLTMH dalam prakteknya tidak mengganggu aliran air irigasi yang digunakan untuk melayani kebutuhan masyarakat petani sebab teknologi PLTMH yang digunakan sebagai pembangkit listrik, hanya memanfaatkan aliran air irigasi dengan jumlah volume tertentu, baik pada terjunan maupun pada aspek kecepatan alirannya. Untuk mengetahui kelengkapan kesiapan pemanfaatan jaringan irigasi untuk PLTMH, perlu dilakukan penilaian (assessment) awal terhadap proses persiapan yang telah dilakukan. Salah satu metode penilaian yang dapat digunakan untuk pembangunan PLTMH adalah dengan menggunakan standar protokol penilaian tenaga air berkelanjutan atau yang dikenal dengan Hydropower Sustainable Assessment Protocol (HSAP).

Abstract:
The development of novel designs for hydropower plants is of high interest nowadays. Studies have shown the negative effect of fluid flow on the turbines of mini-hydropower plants when using them in the conditions of the mountain river. To reduce the damage caused by cavitation, a microplasma coating technique has been chosen. Due to its wetting ability, low density, high thermal conductivity, high heat resistance and low chemical activity, graphite has been studied as a coating material. Vanadium pentoxide has been added as an interlayer to increase the wear resistance, corrosion resistance, and adhesion of the system. The microstructure of the system was studied using scanning electron microscopy and transmission electron microscopy. Functional properties of the system were tested by microhardness tests, wear resistance tests (friction), corrosion tests, and pull-off tests. The surface of the coating was homogeneous without warping, swelling and cracking. The microstructure consisted of regular structures in the form of branches of dendrites. V2O5/C coating resulted in the increase in microhardness up to 2534 MPa. The wear resistance (volume loss) of the sample with double-layer coating was 0.14 mm3 and the maximum adhesion strength was 17.5 MPa. Thus, the double-layer microplasma V2O5/C coating was applied and studied for strengthening the blades of mini-HPP. The microplasma method can find application in modifying the surface of power equipment subjected to the cavitation effect of the river water.

Abstract:
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.

Hydropower is considered to be one of important renewable energy sources. Renewable energy is the second-largest contributor to global electricity production after fossil fuel. Hydropower generation presents several advantages over most other sources of electrical power. It includes a high level of reliability, proven technology, high efficiency (about 90%), very low operating and maintenance costs, flexibility and large storage capacity. Based on the types of installation, hydropower can be categorized as; impoundment, diversion, and pump storage, and based on the turbine types can it be classified as reaction and impulse systems. Previous research gives the results of the initial survey, concluding that there are two rivers that have the potential to become a micro or mini-hydro generator. Way Laai and Way Lami. So, we need to know what is turbines type to suit both of river Way Laai and Way Lami. We used the same method with other research that used TURBNPRO software for helping in the design of Turbines. The simulation result gives one alternative to the right turbine design for Way Laai is the orientation vertical of 6 jet Pelton with a peak efficiency of 89.9%. The right alternative turbine design for Way Lami is the vertical orientation Axial turbine/ propeller design with a peak efficiency of 93.3%.

Abstract:
Water transmission lines have potential reserved energy, which is usually lost. Therefore, targeting this clean energy to produce electricity to power up the auxiliaries and utilities of water plants or consumers is financially and environmentally beneficial. This paper aims to investigate the feasibility of installing an inline hydropower system in an existing transmission water pipe. It analyzes the feasibility of implementing a mini-hydropower plant in the transmission line of Liwa’s reservoir in the UAE. The maximum possible power harvested is 218.175 kW at the given water flow rate and net head. The payback period and the return on investment are analyzed based on different scenarios related to capital investment, operation, maintenance cost, and plant capacity factor. It is found that the payback period ranges between one to six years, where the return on investment can be as high as 85%. Furthermore, the expected CO2 emissions saving for this project is calculated to be between 395 and 1939 tons per year.

Abstract:
Energy is considered as a vital sign of any country. The energy resource of any country is governed by their owned resources either through fossiliferous or alternative/renewable energy reserves. Due to depleting reserves of fossil fuel, countries including Pakistan are now focusing and converting themselves on renewable energy sources. Out of the different renewable sources, Hydel Power is among those indigenous sources which are considered as cheap, efficient and environmentally friendly. Pakistan is among those countries, which have the largest irrigation system which portrays a huge hydel potential within it. Government of Pakistan has also identified different potential sites where Hydel Energy can be obtained. However, apart from the recognized potential sites, there are still many streams/canals/ drains that can also be studied for their hydro potential and estimated generation capacity using mini/micro hydropower plant. Different studies have been carried out in calculating the energy potential of canals. In this paper, Hydropower Potential (HPP) of a Drainage System that is Left Bank Outfall Drain (LBOD), at Sindh has been calculated using field-based data parameters such as hydraulic depth, the width of the canal and flow velocity. Other studies were also reviewed for data collection. Based on the calculated HPP, five types of turbines with their benefits have been identified and proposed. This study concludes that different locations of LBOD can be considered for setting up a micro hydropower plant; however, a vertical head through extended penstock or weir needs to be considered for an effective hydropotential.

Abstract:
Traditionally, power systems are built to take energy from high-voltage levels and distribute it to lower-voltage networks. Transmission networks are connected to major generating units. However, there will be an excessive number of tiny generators connected to distribution networks in the future. The portable power production system is mostly responsible for the excessive energy delivered, particularly when the user is experiencing a breakdown (function). The loss of integrity, as well as the breakdown and failure of electrical power transmission systems, appears to be an issue rooted (problem statement) in the highly practical and applied domains of electrical and power engineering. The objective of this project is to design and construct a portable power production system that uses renewable energy. The research also aims to determine the maximum and sufficient power consumption from solar energy and micro-hydropower systems in order to provide adequate energy for the space in the event of a power fail. The data for this study was collected using a Digital Multimeter, which was used to measure the resistance (R), voltage (V), current (A), and power (W). The results of the test reveal that the portable power production based on renewable energy has enough capacity to create electricity during a power failure as well as provide adequate loads such as LED lights, mini fans, and phone chargers. This study can also be improved by creating a higher-voltage micro turbine motor and a higher-voltage solar panel for the solar system to increase the operation time.

Abstract:
In spite of the very large hydropower potential given from the melting snow and ice of Himalayas, Nepal’s population has little hydropower production. The high use of fossil fuels and biomasses results in measurable air pollution, even in the mountain areas. Hydropower planning and implementation, in the face of the changing climate, is therefore paramount important. We focus here on Nepal, and particularly on the Dudh Koshi river basin, with a population of ca. 170,000 people, within an area with large potential for hydropower production. Our main objectives are to (i) preliminarily design a local hydropower grid based on a distributed run of river ROR scheme, and (ii) verify the resilience of the grid against modified hydrology under perspective climate change, until the end of the century. To do so, we set up and tune the Poli-Hydro semi-distributed glacio-hydrological model, mimicking the complex hydrology of the area. We then modify a state of the art algorithm to develop and exploit a heuristic, resource-demand based model, called Poli-ROR. We use Poli-ROR to assess the (optimal) distribution of a number of ROR hydropower stations along the river network, and the structure of the local mini-grids. We then use downscaled outputs from three general circulation models GCMs (RCPs 2.6, 4.5, 8.5) from the Intergovernmental Panel on Climate Change IPCC AR5, to assess the performance of the system under future modified hydrological conditions. We find that our proposed method is efficient in shaping ROR systems, with the target of the largest possible coverage (93%), and of the least price (0.068 € kWh−1 on average). We demonstrate also that under the projected hydrological regimes until 2100, worse conditions than now may occur, especially for plants with small drainage areas. Days with energy shortage may reach up to nf = 38 per year on average (against nf = 24 now), while the maximum daily energy deficit may reach as high as edef% = 40% (against edef% = 20% now). We demonstrate that our originally proposed method for ROR grid design may represent a major contribution towards the proper development of distributed hydropower production in the area. Our results may contribute to improve energy supply, and living conditions within the Dudh Koshi river. It is likely that our approach may be applied in Nepal generally. Impending climate change may require adaptation in time, including the use of other sources which are as clean as possible, to limit pollution. Our Poli-ROR method for grid optimization may be of use for water managers, and scientists with an interest in the design of optimal hydropower schemes in topographically complex catchments.

Abstract:
In this paper, the idea of the public and common good is analyzed from the standpoint of the environmental policy as a sort of public policy. The analysis and considerations start from the postulate that public goods in the academic public are most commonly observed as natural resources and that their function is to be used for economic and particularly industrial development. What needs redefining, and what should be changed by the environmental policy, is taking the status of the public good to a higher status, having in mind its general characteristic - irreversibility. That dimension of the future to be possessed by the public good is the basis for the survival of the modern society. The work illustrates the distinction of the idea of the public and common good in practice using the example of the Republic of Serbia in the case of the environmental-political problem caused by the construction of a mini-hydropower plant, i.e. the administrative management of the public and common good.

Abstract:
In rural Nepal, micro-hydropower plant mini-grids provide renewable electricity to thousands of communities but the plants often have poor financial sustainability. Widespread uptake of electric cooking in such communities is currently not feasible due to high peak loads and limited capacity. In this paper, we develop a Remote-Areas Multi-Energy Systems Load Profiles (RAMP)-based stochastic techno-economic model for evaluating the economic viability of off-grid communities and improving their financial sustainability by introducing new appliances, productive end uses, and demand-side management measures. The model can be used to understand community electricity demand, assess economic status, determine equitable and profitable tariff structures, and plan new connections including electric cooking promotion or new industrial machines. Detailed electric cooking load modelling functionality was developed to represent Nepali cooking practices, scalable to approximate widespread uptake of electric cooking, and adaptable to other cookers and contexts. The model showed that a payment structure based on electricity consumption rather than a flat tariff could increase the income of a case study community in Eastern Nepal by 400%, although increased monthly payments for certain households from NPR 110 (USD 0.93) to NPR 500–1100 (USD 4.22–9.29) could present difficulty. However, households could reduce their electricity consumption and a more equitable tariff structure could be chosen while preserving plant profitability. The number of industrial machines such as mills could be doubled and up to 40 households provided with electric cookers if demand-side management measures were introduced.

This research discusses the design of risk management strategies in MHP projects in Indonesia. MHP is a type of power plant that uses hydropower to turn turbines for generate an electricity. The MHP project involves a large investment with a long construction period. The length of the construction time, creates an uncertainty factor that impacts on three aspects of the project objectives. The objective aspects of the project are cost, quality, and time. Several MHP projects in Indonesia have underperformed, such as delays in completion time and cost overruns. The risk management process, which consists of risk identification, risk assessment, risk management formulation and risk control, forms the basis of research work. In this study, 23 risks were identified in the MHP project. Fifteen of them have high impact on two aspects and three have high impact on three aspects of project objectives. The results of this study can be used as a guide for risk management in MHP projects in Indonesia. The results of this study can be used as a guide for risk management in MHP projects in Indonesia. It is hoped that the design of this strategy will also help the project to achieve its goals. Furthermore, the results of this research can be used as learning materials in planning the development of MHP in the future.

Abstract:
Microhydro power plant is an alternative for producing small-scale electrical energy uses hydropower. Microhydro has three main components, water, turbine and generator. In the environment , it can also be used as a microhydro power plant on a home scale. The components needed to make microhydro prototype are water reservoirs, valves, MOV,generators, flowmeters, voltage sensors,LED . The water reservoir is installed as high as 4 meters. MOV is used as an actuator to control the flow of water to adjust the degree of valve opening automatically. Generator is connected to convert mechanical energy into electrical energy, flowmeter to determine the debit value and a voltage sensor is connected. The system will be connected to the load of an LED light. When the lamp load changes, it is expected that the voltage generated by the generator remains stable. To regulate the voltage to remain stable, voltage control is carried out by adjusting the degree of valve opening using a PID control system. Voltage control with PID control based on Ziegler Nichols theory with oscillation method. Through experimentation, it was obtained that the KP = 0.9, Ki = 0.45 and Kd = 0.45 constants were the most optimal because the response of the oscillating system was 1.15 seconds shorter. The time required for the voltage to stabilize to the setpoint from the start of the system being turned on is 46.20 seconds. The greater the degree of valve opening, the greater the voltage generated, because the debit produced is greater.

Abstract:
Water supply systems are one of the main hydraulic systems with significant potential for the installation of micro-hydropower devices. Although there are already some mini-hydropower applications in water supply systems, it is still a huge potential that continues to be under-exploited. The arrangement based on an axial turbine, such as an inline tubular propeller, with different diameters and rotational speeds suitable to exploit the existing potential in the water sector, is fully tested. The turbine with the nominal diameter of 85 mm was analysed through experimental campaigns and numerical models for a large range of heads and flow measurements to access its performance. A good correlation between the physical model and the numerical results were obtained, with mean values of deviation less than 5% regarding flow, mechanical power and efficiency. These results were extrapolated to other similar turbine with 170 mm, using affinity laws to investigate the power extraction performance. Both geometries were also numerically investigated using computational fluid dynamics (CFD) models and comparisons were made between the affinity model and experimental results. The results identified differences when compared with the classical affinity curves. Therefore, new formulations based on affinity equations were proposed for the analyzed axial turbine with different diameters without imposing a constant turbine efficiency since actually it does not keep constant as CFD calibrated model proved. Compared to experimental test efficiencies for different rotational speeds, the new proposed affinity laws provided a maximum error of 12% for both diameters.
