铅酸蓄电池生产企业属于高电耗企业，其化成工艺改良节能潜力巨大。基于铅酸蓄电池生产工艺流程，以化成放电时不回馈上游电网和不额外安装大型储能设备为前提，考虑峰谷电价机制，以电池组串化成周期内总电费最低为目标，计及充放电机转换效率，以及充放电机负载功率约束、总化成功率不反馈电网约束、电池组串切换时间间隔约束和化成调度周期内总切换次数约束等，构建铅酸蓄电池化成优化调度模型。以某铅酸电厂实际运行数据为背景，采用粒子群优化算法进行求解，算例结果显示优化后总化成电耗成本节约5％以上。研究结果对铅酸蓄电池企业实施节能增效改造有重要的指导意义。%Lead-acid battery manufacturers belong to the high power energy consumption industry,and they have great energy-saving potential by improving formation process. Considering the peak-valley electricity pricing mechanism,and aiming at minimizing the to-tal power cost of battery packs during a formation cycle,a mathematic optimal dispatching model of lead-acid battery formation is es-tablished based on the lead-acid battery formation process,with the premise that there is no feedback to superior power grid and no ad-ditional large-scale energy storage devices installed. The conversion efficiency of charging-discharging device is considered together with the constraints of load power of charging-discharging devices,no feedback to power grid,switching time interval of battery packs,switching frequency during a formation dispatch cycle. Based on the actual operation data of a lead-acid battery factory,the particle swarm optimization algorithm is used to solve the optimal model. Results show that the total power consumption cost can be re-duced by 5% after optimization. The research in this paper can provide reference for lead-acid battery industry in energy-saving recon-struction and efficiency promotion.
