The shift from conventional towards renewable energies causes a transition from centralized to decentralized generation. Decentralized energy resources lead to challenges but also chances for the operation of future power grids. Therefore, stability and protection phenomena are addressed. Different simulations need to be performed to prove the suitability of future power grids. These simulations include dynamic simulations with high numerical effort. For many applications, this numerical complexity needs to be reduced to ensure real-time capability or to perform simulations for many different systems and scenarios. A method for reducing the numerical complexity is grid aggregation. However, grid aggregation implies an error to the investigations. This error needs to be estimated. In this paper, it is demonstrated that the influence of grid aggregation on the grid's short circuit properties is small enough to use grid aggregation for grid protection studies. The paper's investigations were motivated by similar findings about the influence of grid aggregation on voltage stability properties.
