Power Distribution Loss Reduction Using Cuckoo Search [PDF]

2018 7th International Conference on Computer and Communication Engineering (ICCCE), 2018
The distribution system has the most portion power loss compared to the transmission and generation systems. One of the effective methods to reduce the power loss in the system is by reconfiguring the existing network. In distribution system, there are two types of switches, which are sectionalizing switches and tie-switches.

Practical Considerations for Optimal Conductor Reinforcement and Hosting Capacity Enhancement in Radial Distribution Systems

IEEE Access, 2018
The high penetration level of distributed generation (DG) units may lead to various problems and operational limit violations in electric power distribution systems if it exceeds a particular limit known as the system's hosting capacity (HC).

Optimal passive filter design for effective utilization of cables and transformers under non-sinusoidal conditions [PDF]

, 2014
Transformers and cables have overheating and reduced loading capabilities under non-sinusoidal conditions due to the fact that their losses increases with not only rms value but also frequency of the load current.
