摘要

摘要本文对两种并网能源系统(常规能源系统和可再生能源系统)进行了技术经济分析。调查采用实验测量所需负荷和天气数据(太阳辐照度和环境温度),测量的日能耗为5.1千瓦时,年平均太阳辐照度为4.6千瓦时/平方米/天。仿真过程采用MATLAB和HOMER软件,以1 min的时间步长分辨率完成。提出的两种能源系统方案(1)光伏/电网和(2)柴油/电网的经济优化目标考虑到经济方面和基于伊拉克市场和法规的组件价格。柴油发电机在农村地区非常受欢迎,它被设计成与光伏系统在同一时间段工作(仅在白天)。年运行时数为4380小时/年,发电量约为。2349千瓦时/年,油耗为1826升/年。结果表明,场景(i)下的光伏发电系统可发电约7895 kWh,场景(ii)下的柴油发电机可发电约2346 kWh。此外,对于情景(i),平净当前成本为1079美元,能源成本约为0.035美元/千瓦时,而对于情景(ii),平净当前成本为12,287美元,能源成本为0.598美元/千瓦时。与柴油发电机相比,由于成本最低和向电网输送能量,强烈建议使用太阳能发电机。此外,它可以捕获二氧化碳约5295公斤/年。

Energy visibility of a modeled photovoltaic/diesel generator set connected to the grid
Abstract The paper presents a technical and economic analysis for two energy systems (conventional and renewable) with grid connection. The investigation was carried out using an experimental measurement for the desired load and weather data (solar irradiance and ambient temperature), were 5.1 kWh the daily energy consumption as measured and 4.6 kWh/m2/day the annual average of the solar irradiance. The simulation process was done by using MATLAB and HOMER software at a 1 min time step resolution. The economic optimization objective presented for two energy system scenarios (i) photovoltaic/grid and (ii) diesel/grid, takes into account the economic aspects and component prices based on the Iraqi market and regulations. The diesel generator, very popular in rural areas, is designed to work during the same period as the photovoltaic system (only during day hours). The yearly operating hours were recorded at 4380 h/year, and energy generation was approx. 2349 kWh/year while fuel consumption was 1826 L/year. The results showed that the photovoltaic system in scenario (i) can generate about 7895 kWh, and for the diesel generator in scenario (ii), it can generate approximately 2346 kWh. Furthermore, for scenario (i) the levelized net present cost is $1079 and the cost of energy is about $0.035/kWh, while for scenario (ii) the levelized net present cost is $12,287 and the cost of energy is $0.598/kWh. The use of solar energy is highly recommended compared to diesel generators due to the lowest cost and delivery of energy to the grid. Furthermore, it can capture carbon dioxide by about 5295 kg/year.
