Simultaneity of PV- and wind power-generation from distribution grid perspective

Solar and wind power are volatile resources. Therefore the simultaneity of solar power feed-in and the combination from solar and wind power feed-in is analysed. The aim is to provide basic parameters for planning specifications, which lead to economic and technically sufficient distribution grids in low and medium voltage levels. Recommendations are given for the peak power from renewable feed-in at different grid nodes, because the simultaneity decreases with higher numbers of power plants and more spacious regions covered. Finally all the results are summarized in an simultaneity factor G, whose definition is presented.
