| Abstract | Considering the characteristics of rooftop photovoltaic (PV) array, a new mathematical model of PV array that is suitable for partial shading condition is built based on an engineering model of a solar cell. It is derived theoretically that output voltage of PV array can be expressed by piecewise function. Moreover, a global maximum power point tracking (MPPT) control method based on particle swarm optimisation (PSO) and incremental conductance algorithm (INC) coordination control is put forward under partial shading. When the environmental conditions are stable, MPPT can be achieved by INC control; otherwise, when the external conditions change, global maximum power point of PV systems can be located fast and accurately by PSO. So, the tracking efficiency is improved. Simulation results show that the PSO and INC coordination control methods have better tracking precision. It can be achieved easily and reduce hardware input costs. It also improves the PV array output efficiency. |

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.
