The size and site of distribution generation (DG) integration in the distribution power network (DPN) are critical for power loss (PL) reduction, bus voltage (BS) improvement, and stability enhancement. This chapter optimizes type I DG (photovoltaic system) into the radial DPN via the application of the osprey algorithm (OA). The OA technique optimizes DG's site and size to minimize the real PL and voltage deviation (VD) of radial DPN. The VD minimization improves the VP of DPN. The efficacy of the OA-optimized DG placement is investigated on a balanced radial DPN with 33 buses. OA-optimized PV system inclusion has minimized the PL of the 33-bus radial DPN by 53.23% and improved the minimum voltage magnitude of the test network from 0.9038 per unit (p.u.) to 0.9631 p.u. The simulation results of OA-optimized DG inclusion are compared with different optimization algorithms’ outcomes to examine the effectiveness.
