| Abstract | This paper investigates voltage and reactive power control in radial and closed loop distribution systems and how the presence of distributed generation (DG) affects the control. Comparative analysis between voltage and reactive power control in radial and closed loop feeders, based on coordination of OLTC, substation capacitors (the shunt capacitors installed at the substation secondary bus) and feeder capacitors (the shunt capacitors located somewhere along the feeder) is presented. The known benefit of closed loop operation is examined in a case study. It is shown that the feeder losses and the voltage fluctuation decrease with the change from radial to closed loop operation. The decrease of voltage fluctuation in the feeder is shown not to reduce the OLTC and capacitor operation. It is also shown that in a certain case closed loop operation can even decrease the maximum allowed DG capacity in the feeders. Further, while it is known that the closed loop operation can defer the distribution line upgrade due to load growth, if the contingency operation is taken into account, the closed loop operation will even earlier request the distribution line upgrade. |

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.
