The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...

随着国家经济的快速发展,电网负荷呈梯级式增长,新兴能源产业也出现跨越式的发展,但风能、太阳能等新兴能源受环境影响较大,发电量不稳定且无配套储能装置,无法满足企业实时用电需求,因此,电力储能系统的重要性和紧迫性日益突出。同时,中国东南沿海地区的峰谷电单价差异较大,部份地区尖峰时段电价是低谷时段电价的3 倍,因此,建立工厂的电力储能系统,既可进行削峰填谷,缓解高峰时电力供需缺口,促进电力资源的优化配置,又可有效降低企业用电成本。

电池储能系统被认为是解决可再生能源的不确定性和不平衡性导致的功率不足和频率波动的有效途径。基于此,文中提出了一种基于电池的荷电状态SOC(state of charge)的电池储能系统混合控制策略。首先,文中将电池的SOC、调频和调峰需求划分为不同的区域,并对调频和调峰提出相应的控制策略,提出SOC自恢复控制策略。之后提出储能的混合控制策略,基于电池储能的SOC,将储能的调频与调峰功能与SOC自恢复策略相结合,实现储能对电力系统的优化。最后通过仿真分析验证该控制策略的合理性与应对可再生能源波动的能力。
