| Abstract | The major constraints encountered by a conventional Maximum Power Point Tracking (MPPT) control for Wind Energy Conversion Systems (WECS) are perturbation speed versus control efficiency trade-off, use of mechanical sensors and system dependent characteristics. In view of these drawbacks, this paper presents a novel sensorless adaptive control for MPPT in WECS. The proposed control allows the generator to track the optimal operating point of the WECS under fluctuating wind conditions by an efficient two-step tracking process. The first step adapts an intelligent iterative approach to update the duty cycle of the boost converter to coordinate with the rapid changes in the wind conditions. A novel scanning process is initiated in succession with the iterative approach to counteract the non-constant efficiencies of the generator-converter subsystems in order to fine tune the obtained MPP. The performance of the proposed method is verified in simulation (PSCAD/EMTDC) and experimental results from a hardware prototype are also presented. The proposed method is compared with conventional perturb and observer (P&O) MPPT controller. The obtained results clearly demonstrates that the proposed control is more efficient than other conventional methods. |

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.
