摘要：nature inspired Harris Hawk optimization algorithm for position and rating of distributed generating units in distribution system is proposed in this paper. By installing DGs nearby consumer load centers, line losses can be reduced and voltage profile improves. But penetration of DGs at unsuitable location with unmatched rating will have large impact on distribution systems. This will affect reliability of distribution network, will lessen voltage quality and rises harmonics. Hence there is a requirement of optimization of position and rating DGs before installing in distribution systems. Voltage profile and DG capacity limitation are considered while optimizing DGs. IEEE 33 bus radial distribution system is considered for allocation. Harris Hawk Optimization Algorithm is implemented to optimize position and rating because of its global convergence and reduced calculation liability. Minimization of main objective function is carried out by considering total losses, voltage profile and capacity of DGs. The recommended process is verified on IEEE 33 bus radial distribution system in MATLAB environment and results show the effectiveness of proposed algorithm.
