Techno-economic analysis and modelling of stand-alone versus grid-connected small hydro-power systems – a review of literature

摘要

Hydro-energy has been universally accepted as the most reliable and cost-effective renewable energy source. Among the several types of hydro-power-generation methods, small hydro-power (SHP) system plays a major role in meeting power requirements of remote, isolated hilly areas in a de-centralized manner by tapping water streams, rivulets and canals of small discharge. An SHP system can function either connected with the grid, where it can feed surplus power generated to the grid or as an independent/standalone isolated system exclusively meeting the local demands of remote locations. The authors in this article have made an attempt to summarize the literature available in this context and have come out with a review paper which is believed to be of immense benefit to researchers and policy/decision-makers in arriving at effective solutions to the problems in the related field.
