Behaviour of small scale dispersed PV generation

Abstract

The spread over of the small scale PhotoVoltaic plants requires a central production forecast. The regional meteorological information is not suitable for individual production calculation. We investigated the behaviour of the PV plants in different regions. We have also been looking for the relation between daily irradiation and energy production. We start from a basic assumption then we visualize the appropriate series of data and we calculate the correlation or other factors. Finally we confirm or neglect the initial idea. The geographical extent has significant effect on the daily cumulated production curve. The co-running of the daily power peak in a region is really strict but it has no correlation with the daily irradiation. The daily irradiation is proportional with the daily electricity production. The individual production forecast is not really viable that is why aggregation is necessary. The area of the whole country must be handled by regions.
