| Abstract | In this study, a novel bandpass filter (BPF)-based control strategy is proposed for operating an isolated microgrid (MG) formed by a solar photovoltaic (PV) array and permanent magnet synchronous generator-based small hydro system. Due to intermittencies in the PV array and loads, a battery energy storage (BES) is used to maintain power balancing between load and source. The BES is input to bidirectional converter (BDC), whose output is connected to voltage source converter of DC link and it regulates the voltage of DC link. The charging and discharging currents of the battery are also controlled by BDC. The maximum power is extracted from the PV array using modified incremental conductance-based MPPT control, which is made to operate in derating mode when BES is overcharged. The VSC is used to control the load fluctuations by implementing voltage and frequency control schemes. The BPF-based control technique is used to mitigate harmonics, to provide reactive power compensation and load balancing during unbalanced non-linear loading conditions. It also has the capability of removing DC offset, higher order and lower order harmonics from input load currents, effectively. The performance of this MG is validated on an experimental prototype developed in the laboratory. |

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.
