Centralized Microgrid: Agricultural Load in Rural Areas of Bangladesh

Energy is regarded as one of the most significant challenges confronting humanity; in fact, based on current growth trends, the world will undoubtedly be resource and carbon-constrained; as such, various studies have been conducted in recent years to identify the benefits of using renewable sources to provide the electricity requirements with clean, secure, reasonably priced, and scalable energy. Hybrid renewable energy systems (HRES) can offer reliable, environment-friendly, and cost-effective means for meeting energy demand. The design of a grid-connected microgrid employing renewables, using photovoltaic (PV) and biogas (BG) generator to power agricultural loads for urban areas is presented in this paper. The goals of the optimal design of renewable energy systems include lowering CO2 emissions while also reducing grid energy usage by incorporating more renewable resources for agricultural uses. Hybrid Optimization Multiple Energy Resources (HOMER) pro was used for modeling and simulation for the optimal design of the HRES. The results demonstrate that the grid-connected microgrid with PV and battery outperforms the grid and the standalone renewable power system. In terms of energy cost (0.0236$/kWh), renewable fraction (88.3%), and carbon reduction, the proposed design in this manuscript is a reliable alternative for the agriculture farm.
