| Abstract | In contrast to several studies on variability within or between (virtual) MW-scale photovoltaic (PV) plants [e.g. T.E. Hoff and R. Perez (2010)] we investigated the aggregated behavior of randomly spaced residential PV-systems in a densely populated urban area (≈ 100 $km^{2})$ in and around Utrecht, the Netherlands. The behavior of such a realistic distributed PV-network is assumed to be substantially different than equivalent and regularly spaced PV panels in a compact array. Nevertheless, qualifiers and instruments like inter-system Ramp Rate (RR) correlation and Mean Output Variability (MOV) can be used to generate statistically important information about a generic PV-network. The characteristic decorrelation length scale over which variations between PV-systems reach a distance-independent plateau (within 1 - $e^{-3}$ ≈ 95%), was found to range from 0 to approx. 3 km, with a mean value of between 0.4(2) km and 1.12(17) km for the full year, depending on the time step of the power output time series. This length scale is typical for an urban environment and is important for reduction of variability in aggregated output variability of PV-systems. The distance-independent variability plateau was found to be linearly dependent on daily MOV values. |

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.
