摘要
为分析农村地区适宜的综合能源系统
考虑系统能量来源、储能设置方式、多站协同模式以及并网距离对农村综合能源系统的影响
提出一种农村多区域综合能源系统多时间尺度优化方法。结果显示
农村地区分布式能源系统更适合采用单站独立运行策略。通过多时间尺度调度可提高系统调度精度。不并网情景下
可再生能源系统总成本比化石能源系统高59.36%。并网情景下
当并网距离为20 km时
可再生能源系统经济性优于化石能源补充供应的系统
可再生能源消纳率比孤立运行提高62.5%;当并网距离大于40 km后
化石能源补充供应的系统孤立运行经济性更优
比可再生能源并网系统的成本降低10.15%以上。农村分布式能源系统选择上应考虑农村与电网的距离。
Abstract
To analyze the suitable integrated energy system in rural areas
a multi time scale optimization method for rural multi regional integrated energy systems is proposed
considering the impact of system energy sources
energy storage settings
multi station collaboration mode
and grid connection distance on the rural integrated energy system. The results show that distributed energy systems in rural areas are more suitable for adopting a single station independent operation strategy. Multi time scale scheduling can improve system scheduling accuracy. In the scenario of not being connected to the grid
the total cost of renewable energy systems is 59.36% higher than that of fossil energy systems. In the scenario of grid connection
when the grid connection distance is 20 km
the economic efficiency of renewable energy systems is better than that of systems supplemented by fossil fuels
and the consumption rate of renewable energy is 62.5% higher than that of isolated operation. When the grid connection distance is greater than 40 km
the economy of the isolated operation system of the fossil energy supplementary supply is better
with a cost reduction of more than 10.15% compared to the renewable energy grid connection system. The selection of rural distributed energy systems should consider the distance between rural areas and the power grid.
