| Abstract | Installation of the photovoltaic power system on the roof of houses is increasing rapidly. The photovoltaic power system has two typical problems, one is large power output change depending on climate change, and the other is over voltage in distribution line due to reverse power flow. These problems will be remarkable subjects for large amount of installation of photovoltaic power system in near future. This paper discussed countermeasures for these problems. We propose an output power smoothing method that a dc capacitor is assumed and stored energy is controlled to make the output smooth, an idea for determining the capacity of the capacitor based on measured data is explained. We also propose a flexible control for a photovoltaic power system with active power and reactive power controls against conventional one that has constant unity power factor, because reactive power is able to contribute over voltage suppression in distribution line. Proposed controllers are applied to a photovoltaic power system for a single phase ac output with three wires, and performance is confirmed by ATPDraw simulation. |

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.
