Calculating the infeed of wind and PV-systems for future grid planning based on real measurement data

In most cases, the actual feed-in from renewable energy systems deviates significantly from the actual installed capacity. For this reason, it is essential to take the actual ambient conditions into account when modelling the resulting feed-in. This publication presents an approach for using real measurement data for the consideration of photovoltaic and wind systems. Based on these approaches, a load profile generator is being developed that simulates the active power behaviour of a high-voltage feeder. Finally, an exemplary application of the methodology shows the simultaneities in the maximum feed-in of different high-voltage grids and the share of feed-in from photovoltaic and wind systems in these maxima. These results serve as important input for planning the electricity grid of the future.
