Mathematical and simulation models enable hydroelectric power unit dynamic behavior analysis using computers. In this paper, nonlinear mathematical of all elements in hydroelectrical plant are detailed described. Basic water supply tunnel, surge tank, penstock, turbine synchronous generator. If we want more credible simulations calculation results, have to use differential equations. Using thes...

Hydropower plants (HPPs) contribute a significant share of Russia’s electricity generation. With the prospects developing this sector and harnessing hydroenergy potential, it is necessary to consider methods for modernizing hydroelectric installations. This article examines new method regulating active (Pelton) turbines based on modifying nozzle flow rate through ejection spent liquid from runn...

Abstract Renewable Energy Sources (RES) is the spearhead of current global energy and technological market. However, RES has been part our everyday life for many decades. Hydroelectric energy, prime RES’s, had a pioneer presence at non-interconnected island Crete, where Small Power Plant (SHPP) Agia ceased its operation after eighty years service. Subsequently, owner plant decided to grant perm...

Energy security is one of the main factors in development and diffusion microgrid applications. In networks operating without storage, operation their systems greatly affected by sudden load demand intermittent generation fluctuations. The purposes using energy storage microgrids are stabilizing renewable sources locally, to ensure that production matches demands, participating frequency regula...

As the forecast of inflows to hydroelectric plants is one input information in process SIN operation programming, it important that these forecasts are increasingly assertive so outputs this more consistent with real conditions. The main goal work model a daily inflow using neural network technique whose incorporated into very short-term hydrothermal dispatch optimization program order analyze ...

Landslide stability analysis is the basement of landslide research. To study influence water on reservoir stability, taking a for example in hydroelectric power station based detailed field investigation and operation data, geological conditions, rainfall were considered, slope failure pattern under natural state rain simulated with Mohr-Coulomb criterion after an numerical three-dimensional mo...

Quantitative precipitation estimation and rainfall monitoring based on meteorological data, potentially provides continuous, high-resolution and large-coverage data, are of high practical use: Think of hydrogeological risk management, hydroelectric power, road and tourism. Both conventional long-range radars and rain-gauges suffer from measurement errors and difficulties in precipitation estima...

We consider the optimal scheduling of hydropower plants in a hydrothermal interconnected system. This problem, of outmost importance for large-scale power systems with a high proportion of hydraulic generation, requires a detailed description of the so-called hydro unit production function. In our model, we relate the amount of generated hydropower to nonlinear tailrace levels; we also take int...
