Due to the difficulty in power network reinforcement and the interconnection of more distributed generations, fault current level has become a serious problem in transmission and distribution system operations. The utilization of fault current limiters (FCLs) in power system provides an effective way to suppress fault currents and result in considerable(More)
Distributed generation (DG) and microgrid will play important roles in the future electric network operations. They could improve energy efficiency, minimize environmental impacts and enhance power system reliability. A power scheduling approach considering load/generation changes and time of use (TOU) tariff for a low voltage DC microgrid incorporating(More)
Previous studies have suggested that, with proper planning, distributed generation (DG) could provide system operation and planning benefits such as reduced losses and enhanced reliability. However, the allowable DG interconnection capacity at each site of the existing network is often restricted by fault current level, voltage variation and power flow(More)
An analytical method that can be used to study the optimal topology and maximum capacity of the existing distribution network to accommodate electric vehicle (EV) charging demands is presented in this paper. In order to facilitate a large number of EV integrations, the feeder reconfiguration problem is formulated as a discrete nonlinear optimization problem(More)
