AbstractHydropower plants in Poland currently use only 19% of the river’s energy potential. Development of hydropower is limited by environmental regulations as well as by economic grounds. From the environmental point of view, it is desirable to build small hydropower plants integrated into the local landscape. This paper presents results of the research aimed at estimating the amount of energy that could be produced in the case of small hydroelectric power plants on weirs existing on the Tyśmienica River. There is also a legal framework that should be adapted at hydropower development. It was calculated that the technical capacity of the small hydropower plants that could be built on 4 existing weirs, is 0.131 MW. These power plants could produce 786 MWh of electricity per year. The economic efficiency of this production is currently difficult to assess, because a new support system for renewable energy sources is currently being implemented, which will be a decisive factor for entrepreneurs. It should be borne in mind that potential investments will be made in protected areas within the Natura 2000 network, which may limit their constructing or impose the obligation to assess their impact on selected environmental elements. Location within the protective area does not eliminate such investments, especially when solutions with the least possible environmental impact are used.

The Impact

Environment – a set of components of the natural environment, natural and natural-anthropogenic objects, as well as anthropogenic objects. When carrying out any construction work, it is necessary to assess the impact of emissions of pollutants on the environment. One of the features of the energy sector at the beginning of the 21st century is the strict regulation of its further development with the requirements of preserving a favorable environment and preventing global pollution. This determines the trend towards an increasing role of renewable energy sources and, first of all, the most efficient hydropower. In the world, small energy began to develop in recent decades, this is mainly due to the desire to avoid environmental damage caused by reservoirs of large hydroelectric power plants, with the ability to guarantee energy supply in isolated and inaccessible areas. The creation of small hydroelectric power plants instead of small power plants operating on fossil fuels leads to a significant improvement in the air basin. This article provides an assessment of the ecological state of the territory from the point of view of the possibility of construction of the object and a preliminary qualitative forecast of possible changes in the environment during the implementation of the planned construction works and its negative consequences. Based on the analysis of the initial state of the environment and the forecast of its resistance to man-made impacts, the assessment of the possible impact of the construction object on the environment in accordance with the requirements for environmental documentation was carried out.

Purpose: to assess the technological and regulatory and technical capabilities of developing and applying power supply complexes using the energy of water flow, in relation to Russian standards to meet the electricity needs of decentralized reclamation (irrigation) systems. Materials and methods. Scientific and technical materials of Russian and foreign authors, as well as the regulatory and technical base of the Russian Federation were used as the initial data. The information processing methods were comparison, analogy, classification and systematization. Results and discussion. Among various design features of the hydropower equipment under consideration, capable of meeting local needs for electricity and at the same time having the ability to combine with elements of an irrigation network (based on relative dimensions, shape, efficiency, etc.), micro-hydroelectric power plants stand out: with propeller, radial axial, axial and capsule hydraulic turbine. The most effective schemes for installing hydraulic turbines are horizontal direct-flow and vertical Z-shaped ones. Analysis of the register of standards in the field of technical regulation in the sphere of hydropower showed that out of 131 standards under consideration, 106 can be partially applied to micro hydropower plants. Providing low-power hydropower facilities with standardization documentation has a priority in the direction of operation (21 %), monitoring and state control (19 %), and repair and reconstruction (19 %). Conclusions. The functioning of a micro-hydroelectric power station based on the energy of water movement provides for the use of a set of design solutions, which requires additional study in order to be linked to the elements of reclamation (irrigation) systems. The scope of the considered standardization documents can be extended to small hydropower facilities, taking into account the specific features of their operation. In this regard, there is a need for the development of scientifically grounded provisions of existing or being developed regulatory documents.

The production of electric energy from rivers by using mini, as well as micro hydroelectric power plants, is a very promising solution, especially in rural and isolated areas. Numerous waterways in Croatia and their hydrological and hydrogeological diversity present an opportunity, but also a challenge, for the construction of hydroelectric power plants. Due to the complexity of the water courses’ hydrology, as well as hydrogeological characteristics, it is very hard to determine an appropriate flow pattern (amount), which will be used as an input value for the sizing of hydroelectric power plants. Such analysis will be provided for real case studies in Croatia with special regard to present geological media—media with intergranular porosity (Bednja River), karst media (Gornja Dobra River), and flysch media (Mirna River). Considering different geological media increases the possibility of using the presented methodology on other locations in Croatia, as well in the world. It has been shown that the analyzed rivers definitely have potential for electric energy production, regarding the potential and kinetic river energy. The presented analysis is scientifically original, but also shows the procedure for the determination of the hydro-energy potential of the rivers, as well as for the sizing on the hydropower plants. Hydrology and hydrogeology analyses rounds out the usual hydro-energy analysis, which is in most cases based on basic statistical parameter analysis.

Discharge water from fish farms is a clean, renewable, and abundant energy source that has been used to obtain renewable energy via small hydropower plants. Small hydropower plants may be installed at offshore fish farms where suitable water is obtained throughout the year. It is necessary to meet the challenges of developing small hydropower systems, including sustainability and turbine efficiency. The main objective of this study was to investigate the possibility of constructing a small hydropower plant and develop 100 kW class propeller-type turbines in a fish farm with a permanent magnet synchronous generator (PMSG). The turbine was optimized using a computer simulation, and an experiment was conducted to obtain performance data. Simulation results were then validated with experimental results. Results revealed that streamlining the designed shape of the guide vane reduced the flow separation and improved the efficiency of the turbine. Optimizing the shape of the runner vane decreased the flow rate, reducing the water power and increasing the efficiency by about 5.57%. Also, results revealed that tubular or cross-flow turbines could be suitable for use in fish farm power plants, and the generator used should be waterproofed to avoid exposure to seawater.

Definition Of

The operation feasibility of small hydropower plants in mountainous sites is subjected to the run-of-river flow, which is also dependent on a high variability in precipitation and snow cover. Moreover, the management of this kind of system has to be performed with some particular operation conditions of the plant (e.g., turbine minimum and maximum discharge) but also some environmental flow requirements. In this context, a technological climate service is conceived in a tight connection with end users, perfectly answering the needs of the management of small hydropower systems in a pilot area, and providing a forecast of the river streamflow together with other operation data. This paper presents an overview of the service but also a set of lessons learnt related to the features, requirements, and considerations to bear in mind from the point of view of climate service developers. In addition, the outcomes give insight into how this kind of service could change the traditional management (normally based on past experience), providing a probability range of the future river flow based on future weather scenarios according to the range of future weather possibilities. This highlights the utility of the co-generation process to implement climate services for water and energy fields but also that seasonal climate forecasting could improve the business as usual of this kind of facility.

Abstract We present here three types of controlled boundary value problems for conservation laws arising from energy co-generation, hydraulic flows and water hammer for hydroelectric power plants and control of the open channel flows (shallow water). The novelty of these models, from the mathematical point of view, is that they are described by nonlinear hyperbolic partial differential equations of the conservation laws with (possibly) nonlinear boundary conditions. At their turn these boundary conditions are controlled by some systems of ordinary differential equations. The engineering requirements for such systems are asymptotic stability and disturbance rejection: these properties have to be achieved by feedback control. In our setting the main tool for tackling these problems is a suitable Lyapunov functional arising from the energy identity. The hints for “guessing” this functional are to be found in the linearized version of the aforementioned mathematical objects.

The paper presents the analysis of different types of impact the hydroelectric power plants’ reservoirs could make on the environment. Hydroelectric power plants (HPP) produce ecologically safe energy and correspond to the modern striving for sustainability because they are operated on renewable energy sources. At the same time they can provoke various potential dangers for the environment. The objective of the investigation is to demonstrate the interrelation between the type and structure of a hydroelectric power plant and the way its reservoir may impact on the nature surrounding the plant. These effects may be direct and indirect, positive and negative and vary from insignificant that can be easily fixed to those that are irreversible and catastrophic. The latter should be taken into account during the design of HPP.
