Raising Power Quality and Improving Reliability by Distribution Network Reconfiguration in the Presence of Renewable Energy Sources



In this paper, reconfiguration problem of distribution network has been investigated to
improve reliability and reduce power loss by placement of renewable energy sources; i.e. solar
cell and wind turbine. For this, four reliability indices are considered in objective function;
which are as follows: System Average Interruption Frequency Index (SAIFI), System Average
Interruption Duration Index (SAIDI), Cost of Energy Not Supplied (CENS), and Momentary
Average Interruption Frequency Index (MAIFI). By using a novel technique, the target function
was normalized. Simulation has been performed on IEEE 69-bus test system. A genetic algorithm
could solve this nonlinear problem.
