Design and Optimization of Micro-Grid Hybrid Power System at Kutubdia in Bangladesh

Abstract

Electricity is needed at all times for a country's long-term growth. The power shortage is a significant impediment to Bangladesh's economic growth. At the moment, the majority of electricity supply in the world is based on fossil-fuels, which are not environmentally sustainable and emit greenhouse gases that contribute to global warming. In Bangladesh, the amount of fossil-fuel reserved is insufficient. The abundance of renewable energy sources, such as, Solar energy, Wind energy, Battery, Diesel Generator and power Converter offers renewable options for renewable energy-based microgrid hybrid energy systems in Bangladesh's coastal regions. Renewable power generation systems combined with diesel engines can provide a reliable and integrated supply of energy in isolated or remote areas where grid access is difficult to achieve. This study presents a cost-effective micro-grid power system modeling of a Wind-Solar-Battery-Diesel Generators microgrid hybrid power system in a coastal region of Kutubdia, which is an Upazila in Cox’s Bazar District in Bangladesh. The primary aim of this proposed integrated design is to meet the maximum load demand utilizing renewable energy sources at the lowest possible Cost of Energy (COE). Global warming is a serious issue in today's world. As a result, we see a decrease in both fossil-fuel consumption and carbon-dioxide emissions. This hybrid model was made with the help of a software program called Hybrid Optimization of Multiple Energy Resources (HOMER) PRO. In this scenario, HOMER determines the most cost-effective configurations from a collection of systems with an energy requirement of 812.23 kWh/day primary load and a peak load of 104 kW. The Cost of Energy (COE) is BDT 8.43/kWh.
