This paper investigates the impact of time-varying voltage-dependent load models on hybrid distributed generation planning studies. Firstly, a multi-objective index is constructed with indices namely real and reactive power loss index, voltage deviation index, and mega-volt-ampere capacity index with an objective of reduction of real and reactive power loss, voltage profile improvement, and decreased line loading. The multi-objective index derived is minimised to locate the distributed generation. Secondly, the analytical expression is obtained to size the distributed generation units with the time-varying voltage-dependent load models and probabilistic nature of solar and wind generation. Finally, the impact of load models with the generation effects is separately analysed for PV/wind (hybrid) distributed generation planning. The proposed perspective was validated on the IEEE 33-bus, IEEE 69-bus radial distribution network, and a real 16-bus distribution substation for its effectiveness because the distributed generators are placed in the distribution side of an electrical network. The outcomes reveal that the distributed generation allocation for time-varying voltage-dependent load model and probabilistic nature of solar and wind has significant impacts on the distribution system by reducing real and reactive power loss, improving voltage deviation and reduced mega-volt-ampere intake.
