Simulation analysis of current protection in distributed power distribution network
Journal of Physics: Conference Series, 2020 Abstract The massive access of distributed power sources makes the distribution network into an active network with bidirectional power flow, which increases the economics and flexibility of grid operation. However, the protection configuration of traditional distribution systems is based on a single power system.
