| Abstract | This paper presents an analysis of inherent cell mismatch in PV modules and its impact on Maximum Power Point Tracking (MPPT) achieved via buck-boost converter control. Inherent cell mismatch is defined as mismatch induced within the module stemming from manufacturing imperfections or long-term degradation processes such as delamination. We model the mismatch processes in a module by considering various distributions in the cell parameters of a one-diode model such as series and shunt resistances. In order to study the impact of inherent cell mismatch on power output we developed, in Matlab Simulink, a PV module model where the parameters of each PV cell can be configured dynamically. The model also includes a DC-DC buck-boost converter and MPPT controller using a simple Perturb and Observe (P&O) algorithm. The impact on MPPT due to various distributions of PV cell parameters is reported. Since the parameters can be dynamically changed, we are also able to study the impact on MPPT due to parameter variations occurring over both slow and fast time-scales. |

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.
