Abstract

This paper provides an alternative approach for improving voltage stability and minimizing power losses through distribution system reconfiguration and adjusting the capacities of the Distributed Generators (DGs). The problem is formulated as multi-objective functions. Multi-objective genetic algorithm is utilized to evaluate the highest system loadability and minimum power losses by optimally sizing the distributed generators along with optimal network reconfiguration. The proposed technique is applied to IEEE 69-bus radial distribution system. The results showed the effectiveness of the proposed approach in improving the voltage profile and reducing in the power losses of the system.
