4.2.11. Distribution Systems

Prasad et al. [162] used EHO to determine the optimal distributed generation (DG) unit size. The proposed model was performed on two types of DG (DG operating at 0.9 power factor lag and DG operating at unity power factor). The numerical results indicated that the EHO algorithm obtained overall better results compared with other algorithms in terms of reducing power consumption.

Vijay et al. [163] applied the EHO technique to the optimal placement and sizing of distributed generation on an electric distribution network. EHO was tested on a 5-bus radial distribution system. The results indicated that the overloading of the equipment, active power, reactive power, and production cost of electricity were reduced, which was more intelligent and precise for the allocation of distributed generation in an electric distribution network.
