Electrical distribution network reconfiguration is a complex combinatorial optimization process aimed at finding a radial operating structure that minimizes the system power loss or/and maximizes the system reliability while satisfying operating constraints. In this paper, a distribution network reconfiguration method is presented for both the indices of power loss reduction and reliability imp...

We have proposed an Autonomous Disks for the advanced data management. The Autonomous Disks provide data distribution and high reliability. The Autonomous Disks configure a cluster and handle access from host in the cluster. In this paper, we propose dynamic reconfiguration algorithms allowing the usual operations dulling the reconfiguration, and implement them on an experimental system using J...

Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...
