| Abstract | A large number of Photovoltaic Generations (PVs) are expected to be introduced in distribution systems (D/Ss). Therefore the state estimation is important problem for stable and reliable system operation. However, it is difficult to estimate the total power of PVs connected to a D/S because metering spots and metering items are limited in existing D/S. In this paper, we propose an estimation method for sum of PV-outputs connected to a D/S. This method enables to estimate PV-outputs by analyzing a power flow data which include PV-outputs and various distribution loads using independent component analysis (ICA). The estimation by ICA needs the same number of observation signals as estimation signals. So we propose the method which is able to estimate PV-outputs and load-changes from active and reactive power flow those are recognized as two observation signals measured at one observation point on distribution lines. And the information of insolation as a priori knowledge is added to the method improving the estimation accuracy. |

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.
