Projects for constructing Small Hydro power stations and possibilities of making their use more efficient
Thermal Engineering, 2012Co-Authors: Ya. I. Blyashko, V. E. ShpitsbergAbstract:The results obtained from development and substantiation of projects for constructing Small Hydro power stations in Buryatia are described, and the technical-and economic indicators of these projects are presented. A new approach for estimating the Hydro power resources of the region is proposed. The possibility of achieving more efficient use of the hydraulic energy produced by Small Hydro power stations in the periods of low electric load is considered through converting the excess electric energy into useful low-grade heat for supplying hot water to independent consumers and for heating them.

Reduced converter topology for integrated wind and Small-Hydro energy generation system
IET Renewable Power Generation, 2015Co-Authors: Bhuvanesh Singh, K. K. BhallaAbstract:This study presents a robust and cost-effective microgrid topology for integrating two commonly available wind and Small-Hydro renewable energy sources. The proposed topology has two generators, one of them is self-excited squirrel cage induction generator driven by a Small-Hydro turbine and other one is permanent magnet brushless DC generator driven by a Small-scale wind turbine. The proposed system is integrated using a voltage source converter and a boost converter which are maintaining voltage and frequency, mitigating power quality problems and performing mechanical sensorless maximum power point tracking, respectively. A battery bank is also used to balance the load and supply power mismatch and to ensure the supply for critical loads. The proposed control algorithm is tested and verified on a developed laboratory prototype of the system. Test results verify that voltage and frequency of the system are regulated and the power-quality-related issues are also resolved in this microgrid.

Small Hydro power: technology and current status
Renewable and Sustainable Energy Reviews, 2002Co-Authors: O. PaishAbstract:Abstract Hydropower, large and Small, remains by far the most important of the “renewables” for electrical power production worldwide, providing 19% of the planet’s electricity. Small-scale Hydro is in most cases “run-of-river”, with no dam or water storage, and is one of the most cost-effective and environmentally benign energy technologies to be considered both for rural electrification in less developed countries and further Hydro developments in Europe. The European Commission have a target to increase Small Hydro capacity by 4500MW (50%) by the year 2010. The UK has 100MW of existing Small Hydro capacity (under 5MW) operating from approximately 120 sites, and at least 400MW of unexploited potential. With positive environmental policies now being backed by favourable tariffs for ‘green’ electricity, the industry believes that Small Hydro will have a strong resurgence in Europe in the next 10 years, after 20 years of decline. This paper summarises the different Small Hydro technologies, new innovations being developed, and the barriers to further development.
