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.
