In recent years, the power sector of Bangladesh has seen a major development in terms of generation capacity. But as before, it is heavily dependent on fossil fuels overlooking the potential of renewable energy resources. The scope for grid-connected renewable energy systems has not been explored too far and in terms of solar thermal energy and concentrating solar power (CSP), it is even less. This study focuses on assessing the techno-economic feasibility of solar-driven Dish Stirling system for large-scale grid-connected power generation in Bangladesh. Detailed modeling and optimization of a 100 MW Dish Stirling power plant have been carried out in Cox's Bazar, Bangladesh, a location suitable for solar energy harnessing due to favorable climatic conditions. The modeling parameters and weather data have been collected from relevant literature, various solar data providers, and specific plant parameters have been optimized for the Bangladeshi climatic condition. Simulation of the modeled plant carried out by the System Advisor Model (SAM) shows that, it can supply 129.856 GWh electricity annually operating at an overall efficiency of 24.91% which is much higher than the values reported in similar literature for the South-Asian regions. The levelized cost of electricity (LCOE) has been determined to be 10.18 cents/kWh, which is highly competitive and promising. The insights obtained from this study can be a perfect starting point for the policymakers and concerned authorities of Bangladesh to further explore the viability of this technology for renewable and sustainable power.
近年来，孟加拉国电力部门在发电能力方面取得了重大发展。但和以前一样，它严重依赖化石燃料，而忽视了可再生能源资源的潜力。并网可再生能源系统的发展空间尚未得到充分探索，就太阳能热能和聚光太阳能发电（CSP）而言，情况更是如此。本研究着重评估太阳能碟式斯特林系统在孟加拉国大规模并网发电的技术经济可行性。在孟加拉国科克斯巴扎尔对一座100兆瓦的碟式斯特林发电厂进行了详细建模和优化，该地区气候条件有利，适合太阳能利用。建模参数和气象数据取自相关文献、各类太阳能数据提供商，并针对孟加拉国气候条件对特定电厂参数进行了优化。系统顾问模型（SAM）对建模电厂进行的模拟显示，该电厂每年可发电129.856吉瓦时，整体效率为24.91%，远高于南亚地区类似文献报道的值。平准化度电成本（LCOE）确定为10.18美分/千瓦时，极具竞争力且前景广阔。本研究获得的见解可为孟加拉国政策制定者和相关部门进一步探索该技术用于可再生和可持续电力的可行性提供完美的起点。
