Optimizing the Grid Connection of Hybrid PV and Wind Power Plants
Abstract
In order to economically optimize the grid connection of a hybrid renewable power plant consisting of photovoltaic (PV) generation and wind turbines, the simultaneity of production from both energy sources should be taken into account. In this work, high-resolution feed-in data from such a hybrid power plant was recorded and evaluated. The results allow for an estimation of maximum energy curtailment in case of an undersized point of common coupling (PCC). Additionally, it is evaluated how the ratio between the PV and the wind part of a hybrid power plant influences the optimal PCC dimension and the expected curtailment losses. With this knowledge, it is possible to find a cost-optimal solution for the layout and the grid connection of a combined PV / wind power plant.
