The establishment of grid-connected prosumer communities to bridge the demand-supply gap in developing nations, especially in rural areas will assist to minimize the use of carbon enriched fossil fuels and the resulting economic pressure. In the promoted study, an economic and ecosystem-friendly hybrid energy model is proposed for grid-connected prosumer community of 147 houses in district Kotli, AJK. The grid search algorithm-based HOMER software is used to simulate and analyze the load demand and biomass sources-based onsite collected data through a survey for an optimal proposed design. The research objectives are to minimize the net present cost (USD) of design, the per unit cost of energy (USD/kWh), and the carbon emissions (kgs/year). A sensitivity analysis based on photovoltaic module lifetime is also performed. The simulations show that the per unit cost of energy is reduced from 0.1 USD/kWh to 0.001 USD/kWh for the annual energy demand (kWh/year) of the community. The number of carbon emissions is also minimized from 122056 kgs/year to 1628 kgs/year through the proposed optimal energy model.
建立联网型能源消费者社区,以弥合发展中国家(特别是农村地区)的供需差距,将有助于最大限度地减少使用富含碳的化石燃料和由此产生的经济压力。在本研究中,提出了一种经济和生态友好型混合能源模型,用于连接 147 户家庭的联网型能源消费者社区,该社区位于 AJK 地区的科特利区。基于网格搜索算法的 HOMER 软件用于模拟和分析通过调查收集的基于负载需求和生物质资源的现场数据,以进行最佳设计的优化。研究目标是最小化设计的净现值(美元)、能源单位成本(美元/千瓦时)和碳排放(公斤/年)。还对基于光伏模块寿命的敏感性分析进行了研究。模拟结果表明,对于社区的年度能源需求(千瓦时/年),能源单位成本从 0.1 美元/千瓦时降低到 0.001 美元/千瓦时。通过提出的最佳能源模型,碳排放数量也从 122056 公斤/年减少到 1628 公斤/年。
