Butterfly optimizer-assisted optimal integration of REDG units in hybrid AC/DC distribution micro-grids based on minimum operational area

Abstract This paper presents the impact of optimal location and sizing renewable non-renewable-based distributed generators in AC/DC micro-grid system using latest optimizer called butterfly optimization algorithm with an aim to minimize power loss. Generally, hybrid micro-grids systems are modeled by separating AC DC feeders help high-power converters (HPC).AC grids sustained substation maintained their individual DG units. While planning DGs systems, loss incurred HPCs is not considered avoiding complexity many authors. In this paper, determined operational area required type technology as one variable all possible candidate buses respective zones another due consideration HPC losses system. A MG developed classifying existing benchmark 33-bus 69-bus radial distribution into various zones. To evaluate proposed approach, it implemented on aforementioned obtained results verified other approaches literature. The proved that approach better than technical aspects.
