| Abstract | With the higher penetration of renewable energy into modern power system, power electronics converters are most commonly employed as the interfaces to the grid. At the same time, to deal with high frequency harmonic components, LCL filters are usually adopted. Although compared to L-filters, LCL filter has higher power density, its resonance problem should be noticed. In a large renewable energy farm, multiple converters inside are connected in parallel. In this way, the analysis of the resonance problem should be expanded. Compared to a conventional single LCL filter system, additional resonance peaks appear in frequency domain analysis results in parallel system. At the same time, considering the capacitor for local reactive power compensation, additional resonance peak in the low frequency range appears. Greater challenges are brought to the system stability. Meanwhile, the harmonic performance is also influenced. In this paper, the resonance propagation of parallel converter system with a local capacitor for reactive power compensation is analyzed in detail. Simulation and experiment results support the theoretical analyses. |

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.
