摘要
由于自然资源的枯竭,可再生能源系统(RES)正变得越来越突出。混合可再生能源的最佳尺寸是必要的,以确保可再生能源渗透。不适当的尺寸可能导致较高的启动成本或无法满足各种天气条件下的负载需求。通过对混合优化多能源系统(Hybrid Optimization Multiple Energy Resources, HOMER pro)的分析,给出了能源生产、排放等成本最低的理想混合能源系统。本研究提供了一个并网混合电力系统模型,该模型基于从孟加拉国达卡Mohammadpur的一栋住宅楼收集的计量数据。太阳能是一种可持续能源,因此降低了系统的成本,这也是环保的。这种可再生能源还有助于最大限度地降低能源平准化成本(COE)。结论估计了微电网系统两种组合的运营成本、生产成本、净现值成本和能源成本。根据仿真结果,通过微电网向负载供电将是一种可行且经济有效的解决方案。
Techno Economic Feasibility Analysis of Grid-Connected Microgrid by Using Solar PV for Residential Usage
Renewable energy systems (RES) are becoming more prominent because of the depletion of natural resources. Optimum sizing of the hybrid RES is necessary to ensure that renewable energy sources penetrate. Improper sizing may result in higher initiating costs or an inability to meet load demand under various weather conditions. By analyzing with Hybrid Optimization Multiple Energy Resources (HOMER pro), this study shows the ideal hybrid energy system that provides the lowest cost of energy production, emissions, and so on. This study provides a grid-connected hybrid power system model based on metrological data collected from a residential building in Mohammadpur, Dhaka, Bangladesh. Solar energy is used as a sustainable energy source thus the cost of the system was decreased, which is also environmentally friendly. This renewable energy also helped to minimize the levelized cost of energy (COE). The conclusion estimates operational costs, production costs, net present cost, and energy cost for the two combinations evaluated for the proposed microgrid system. According to the simulation results, delivering power to the load via a microgrid would be a viable and cost-effective solution.
