Abstract: The sharp increasing power demand and configuration changes in distribution networks (DNs) may operate the network more closely to voltage stability (VS) boundaries. Under critical operating conditions, the DN is not able to provide good voltage profile and may experience voltage collapse. Distributed generation (DG) has been popularly used in supplying real and reactive power in DNs. This paper builds the DG placement problem (DGPP) as a multi-objective optimisation problem with objectives of the lowering real power loss, enhancing the voltage profile, improving the VS and lowering the net operating cost; and suggests a solution scheme involving flower pollination-based optimisation (FPO) for optimally placing DGs in DNs. The FPO is a nature inspired algorithm of modelling the pollens of flowers as problem variables and the pollination process for optimising the (flowers) problem variables. The FPO in DGPP finds optimal nodes for DG placement in addition to sizing the DGs. It presents simulation results on standard IEEE DNs with a view of portraying the supremacy of the suggested strategy.
