Abstract | A novel topology with a bi-directional DC/DC for stand-alone wind power system is adopted, which can maximize the battery life by monitoring and controlling its state of charge(soc) and charge/discharge process. According to the atmospheric conditions, the state of charge of the battery and the load conditions, six possible operation modes of the bi-directional DC/DC are also expounded. This paper proposes a hybrid control strategy with the combination of the PI control and the direct output current control to avoid the voltage surge of the DC bus caused by the mode switching. A 5kW wind power system test bench is developed to verify the effectiveness of the control strategy. The experimental results show that the voltage surge can be limited within 5% and the controller performs well in various wind speed and load conditions. |

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.
