Cost optimal design of micro hydel systems

Micro hydel systems are turning out to be an important choice for power generation as a renewable energy source, considering the hydel resource available in India. Reports from Ministry for New Renewable Energy (MNRE) states that the estimated potential for power generation in India from hydel plants is about 15,000 MW from 5718 identified sites. Researchers are trying to develop hydel systems with induction generators, operating both in grid-tied and stand-alone modes. This paper describes an optimization model which gives a cost optimized design for micro hydel systems. The model is applied to obtain an optimal design at a typical site in Kerala.
