【摘要】：電池壽命過(guò)短和配置空間有限是現(xiàn)代有軌電車(chē)儲(chǔ)能系統(tǒng)應(yīng)用存在的重要問(wèn)題,給其能量管理策略和容量配置方法的設(shè)計(jì)帶來(lái)了挑戰(zhàn)。該文首先對(duì)影響電池壽命的因素進(jìn)行了分析,建立了壽命估計(jì)模型。針對(duì)電池與超級(jí)電容混合儲(chǔ)能系統(tǒng),提出了基于加速時(shí)間預(yù)測(cè)的能量管理策略:根據(jù)車(chē)輛加速時(shí)間計(jì)算超級(jí)電容的實(shí)際可用功率,進(jìn)而決定電池和電容的功率分配。該策略基于有軌電車(chē)運(yùn)行周期性確定加速時(shí)間預(yù)測(cè)窗口,并充分考慮超級(jí)電容放電時(shí)間。仿真和實(shí)驗(yàn)驗(yàn)證了該策略具有充分利用超級(jí)電容能量和減弱電池壽命衰減的良好效果。同時(shí),分別基于基本閾值策略和加速時(shí)間預(yù)測(cè)控制策略進(jìn)行優(yōu)化容量配置,分析不同控制策略對(duì)容量配置結(jié)果的影響。結(jié)果表明該文的策略通過(guò)降低超級(jí)電容的配置要求以及延長(zhǎng)電池壽命實(shí)現(xiàn)了全壽命周期成本的降低。
[Abstract]:Battery life is too short and the allocation of limited space is modern tram storage systems is an important problem in application, bring challenges to the design of the energy management strategy and capacity allocation method. This paper first analyzes the factors affecting the battery life, establish the life estimation model for hybrid storage battery and super capacitor can system, energy management strategy was proposed based on the prediction of the acceleration time: according to the actual power available vehicle acceleration time calculation of super capacitor, and then determines the power allocation for batteries and capacitors. The strategy based on periodic running trolley determine acceleration time prediction window, and give full consideration to the super capacitor discharge time. Simulation and experimental results verify the strategy can make full use of super capacitor energy and decrease battery life attenuation with good results. At the same time, based on prediction threshold strategy and acceleration time The control strategy is used to optimize the capacity allocation and analyze the influence of different control strategies on the capacity allocation results. The results show that the strategy reduces the life cycle cost by reducing the configuration requirements of the super capacitor and prolonging the battery life.
