中文摘要:
      独立型光储微电网作为光伏应用的有效形式得到了广泛的使用,其中系统的经济性优劣主要依赖储能的类型和配置调控方案。基于此,文章根据独立光伏系统的建模思想,在给定负荷变化规律的前提下,以最大化利用光伏输出能量为目标,建立光伏能量最大化利用模型,将光伏发电单元和储能单元作为整体进行容量优化配置,通过算例分析,获得目前较为典型的5种储能电池和光伏容量的优化配置结果,在此基础上,为使系统经济性最优,进一步引入年均成本为目标并建立相应模型,得到了5种电池和混合储能电池的经济对比分析结果,最后对5种电池对应的放电时间、循环效率和寿命进行了敏感性分析。结果表明,在同等配置条件且满足项目指标的要求下,能量型铅酸电池和功率型铅酸电池组成的混合电池具有更好的经济性,其次为钠硫电池和铁锂电池,全钒液流电池成本最高。
英文摘要:
      As an effective form of photovoltaic application, the independent optical storage micro grid has been widely used, and the economy of the system mainly depends on the type of energy storage and configuration control scheme. Based on this, according to the independent photovoltaic system modeling thought, in a given load variation law under the premise of output to maximize the use of solar energy as the goal, establishing the model of photovoltaic energy to maximize the use of photovoltaic power generation unit and energy storage unit as a whole will capacity optimization configuration, through the example analysis, get the more typical 5 kinds of the optimal allocation of energy storage batteries and photovoltaic capacity as a result, on this basis, to make the system economy, further introducing the average annual cost as the objective and corresponding model is established, the five kinds of batteries and hybrid energy storage battery economic contrast analysis, Finally, the sensitivity analysis of the discharge time, cycle efficiency and life of the five kinds of batteries was carried out. The results show that under the same configuration conditions and meeting the requirements of the project, the hybrid battery composed of energy type lead-acid battery and power type lead-acid battery has better economy, followed by sodium sulfur battery and lithium iron battery, and the total vanadium flow battery has the highest cost.
