Optimal Allocation of Multiple Distributed Generations in Radial Distribution Systems Using Levy Flight Distribution Algorithm

In this work, the newly metaheuristic Levy Flight Distribution (LFD) optimization technique is implemented for optimal allocation of distributed generations (DG) in radial distribution systems (RDS). The integration of DGs elevates the performance of the distribution systems. The system performance improvement appears in reducing the power losses and voltage deviation and maximizing the system stability. Different numbers of DGs operating at unity power factor (UPF) and optimal lagging power factor (OLPF) are used to achieve the various objectives. The IEEE 33-bus RDS is used as the test system. The obtained results verify the value of the LFD algorithm for solving the DG allocation problem.
