ABSTRACT = {In this research work, the localized generation from renewable resources and the distribution of energy to agricultural loads, which is a local microgrid concept, have been considered, and its feasibility has been assessed. Two dispatch algorithms, named Cycle Charging and Load Following, are implemented to find the optimal solution (i.e., net cost, operation cost, carbon emission. energy cost, component sizing, etc.) of the hybrid system. The microgrid is also modeled in the DIgSILENT Power Factory platform, and the respective power system responses are then evaluated. The development of dispatch algorithms specifically tailored for agricultural applications has enabled to dynamically manage energy flows, responding to fluctuating demands and resource availability in real-time. Through careful consideration of factors such as seasonal variations and irrigation requirements, these algorithms have enhanced the resilience and adaptability of the microgrid to dynamic operational conditions. However, it is revealed that both approaches have produced the same techno-economic results showing no significant difference. This illustrates the fact that the considered microgrid can be implemented with either strategy without significant fluctuation in performance. The study has shown that the harmful gas emission has also been limited to only 17,928 kg/year of , and 77.7 kg/year of Sulfur Dioxide. For the proposed microgrid and load profile of 165.29 kWh/day, the net present cost is USD 718,279, and the cost of energy is USD 0.0463 with a renewable fraction of 97.6%. The optimal sizes for PV, Bio, Grid, Electrolyzer, and Converter are 1494, 500, 999,999, 500, and 495 kW, respectively. For a hydrogen tank (HTank), the optimal size is found to be 350 kg. This research work provides critical insights into the techno-economic feasibility and environmental impact of integrating biomass-PV-hydrogen storage-Grid hybrid renewable microgrids into agricultural settings.},
