Handling uncertainty in natural inflow is an important part of a hydroelectric scheduling model. In a stochastic programming formulation, natural inflow may be modeled as a random vector with known distribution, but the size of the resulting mathematical program can be formidable. Decomposition-based algorithms take advantage of special structure and provide an attractive approach to such probl...

Surplus electricity can be converted into potential energy via pumped hydroelectric storage for future usage. Similarly, thermo-electric energy storage (TEES) uses heat pumps equipped with thermal storage to convert electrical energy into thermal energy; the stored energy is then converted back into electrical energy when necessary using a heat engine. The greatest advantage of this method is t...

The Middle Iskar cascade is situated along the middle course of the Iskar River (Bulgaria) after the capital city Sofia and has three small hydroelectric power plants that were put into operation by the end of 2012. The aim of this study was to evaluate the self-purification potential of water in the reservoirs of these plants as an important and necessary condition for their ecological functio...

The operation of many the engineering systems that are necessary for functioning a detached residential building depends on specific sources alternative energy, use which can significantly reduce consumption traditional fossil energy resources. A review scientific works devoted to using is given. Several schemes power equipment have been developed obtain thermal and electrical supplied isolated...

Slapy hydroelectric plant (HPP) is a typical mid-head HPP hosting three 50 MW Kaplan turbines on the Vltava river, 50 km south of Prague, Czech Republic. The gross head is 47 ÷ 53 m in normal operation regime. Pressure-time (PT) flow measurement method was specified for the acceptance tests of the upgraded Unit #3 in autumn 2011 and OSC had the contract for those tests. ASL AQFlow proposed to b...

In order to solve effectively the issue of remote online detection and fault diagnosis of hydroelectric generating units in FengMan hydropower plant, a kind integrated project of combining embedded network fusion with multi-sensor consistency information fusion algorithm and fuzzy comprehensive assessment algorithm is proposed based on distributed and embedded architecture. Multi-sensor consist...

as part of BPA's program to protect, mitigate, and enhance fish and wildlife affected by the development and operation of hydroelectric facilities on the Columbia River and its tributaries. The views in this report are the author's and do not necessarily represent the views of BPA. This report covers one of many topics under the Yakima/Klickitat Fisheries Project's Monitoring and Evaluation Pro...
