This package is now archived. The network reduction functionality has been now integrated into PowerNetworkMatrices.jl and it doesn't modify the system input data.
The PowerSystemsReduction.jl package provides utilities and routines to reduce the size and complexity of a System represented in PowerSystems.jl. Use with care as it modifies the input data.
