| Abstract | In this study, networked control scheme applied in dq0 coordinate for three-phase parallel inverters of distributed generation units is presented to achieve flexible current weighting distribution. Firstly, the output impedance based on generalised state space averaging method with the consideration of dead-time effect is investigated in dq0 coordinate and proved to be inductive for fundamental components in dq0 coordinate. Therefore the weighted output current distribution can be realised conveniently with networked control applied in dq0 coordinate without the additional circuit or virtual impedance. Besides, for the sake of flexibility and autonomy of a parallel inverters system, the power proportional coefficients of different inverters can be changed automatically. In the end, power weighting coefficients in networked control are optimised by means of functional analysis. The experimental results demonstrate the effectiveness of a networked control scheme applied in dq0 coordinate on the flexible power weighting distribution for parallel inverters. |

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.
