| Abstract | Distributed photovoltaic (PV) systems are being gradually integrated into distribution systems with the advantage of economy, environmental protection, and flexibility. Hosting capacity (HC) of a distribution system limited the integration of the PVs. To identify the economic efficiency of HC, two boundaries of HC for distribution buses are proposed considering the technology and economy. Then, new evaluation metrics that can identify the HC region for the PV buses are presented. A bi-level optimisation dispatch method based on iterative particle swarm optimisation for PVHC enhancement is proposed considering the benefits of both distribution network operators and PV owners. At the upper level, a linear power flow-based model is used to determine the economic PVHC and technological PVHC. At the lower level, the objective function of the maximisation of benefits for PV owners is presented. The punishment coefficient of the PVHC region is incorporated into the optimisation dispatch model. Finally, the demonstration is performed on modified PG&E 69-bus and IEEE 123-bus distribution systems. The simulation results show that the proposed bi-level optimisation dispatch method can effectively increase the PVHC margin of distribution buses, and the presented evaluation metrics are of great practical significance in a deregulated environment. |

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.
