| Abstract | This study proposes an approach for off-grid micro-hybrid system model to represent the locally available sustainable and renewable energy sources (RESs). This model is comprised of wind and solar energy as primary sources along with a pumped storage unit (PSU) as backup. The proposed PSU is modelled with pico-hydro turbines (PHTs) and an open well. The ground water in the open well is effectively utilised along with agriculture and domestic needs in rural areas. The depth of the open well is exploited as the working head for the PHT. The power dispatch of two PHTs at a constant operating head, using the standard lambda iteration method, is obtained ensuring optimal utilisation of the stored water. The performance of the proposed model is tested using solar irradiance and wind speed data during winter and rainy seasons. The ratio of expected input energy and load demand on the succeeding day is used to control the water discharge on the current day. This model taps the unused potential of the open well as an energy storage system. Thereby, it limits the usage of batteries in satisfying the basic load demand of domestic consumers who do not have access to grid electricity. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
