With the development of Smart Grid, the permeability of distributed generation (DG) is increased gradually. When a fault happens in systems branch, DG plays a significant role in ensuring a continuous supply to the load points as many as possible. This paper uses ant colony algorithm to achieve distribution network fault reconstruction with distributed generation, in order to guarantee the load points to restore power as many as possible, and the network system having the minimum loss at the same time. The optimization process is divided into two parts: first, In case of DG power supply capacity known, we optimize the capacity of the Island formed on DG, in order to determine the nodes of the island. Then, we optimize the isolated system and the main distribution system separately, in order to find the system radiation structure of minimum network loss. Finally, the IEEE 33 nodes distribution network is used as an example to testify the effectiveness of ant colony algorithm.

This study addresses the effective mitigation of power quality disturbance such as unbalanced voltage, voltage fluctuation, voltage variation of secondary distribution network using dynamic voltage restorer (DVR). To make distribution system operate at its best performance and minimum loss, DVR is employed. The proposed system is designed using MATLAB/Simulink in Sim Power System tool box. Considering, nevertheless, that standard acceptable performance implies correct voltage profile, minimum loss, no phase shift for voltage and current, absence of overloading of transformers and electrical wires, and acceptable frequency deviation. The new setup of DVR has been put forward using dq0 controller and proportional integral (PI) controller method to improve voltage profile, correct unbalance voltage and enhance power quality problems in secondary distribution network. The simulation results attest to the ability of the proposed DVR configuration in mitigating the power quality problems in secondary distribution network.
