| Abstract | It has been demonstrated that performing localized maximum peak power tracking (MPPT) on each photovoltaic (PV) panel, instead of using a single MPPT controller across the PV string can substantially increase the total harvested power, since each panel experiences unique illumination and temperature conditions. In this work, the effect of the dc-dc converter efficiency on the power savings from distributed MPPT (DMPPT) is analyzed for a wide range of test cases and different PV panel parameters. The benefit of DMPPT for a practical system is shown to be up to 25% for a standard deviation of σ= 0.2. A set of modular hardware-based PV panel emulators (ePVs) is presented. The ePVs can be programmed to match the unique i/v curves of real panels under various conditions and can therefore be used to optimize future DMPPT systems. |

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.
