Abstract: Abstract A microgrid is a collection of distributed energy resources (DERs) It might encompass both traditional and unconventional energy sources. The way a microgrid functions determines whether it is categorized as either islanded or grid-connected. The focus of this study is to explore five different optimal scheduling operation scenarios for Distributed Energy Resources (DERs) with the aim of achieving economic benefits for a low voltage microgrid system. The scenarios being studied are developed using several approaches to grid participation and pricing strategies within the power market. The optimization tool used in the research was the Crow Search Algorithm (CSA), a widely recognized and recently developed algorithm known for its speed and efficiency. The results of the study indicate that the microgrid's most profitable operational scenario involved active participation of the grid in the purchase and sale of electricity, utilizing a dynamic pricing approach based on time-of-usage (TOU). Based on numerical data, the Crow Search Algorithm method produced solutions of superior quality in less time compared to several other algorithms with similar designs that were employed in the study. The CSA approach was able to achieve this consistently, regardless of the scale of the problem being addressed.
