摘要储能电站的安全稳定运行,备受业界关注。大功率等级的储能电站离不开若干储能电池舱间联合运行,合理的功率分配是保障储能电站运行安全、提升效率的重要手段。因此,该文针对典型的锂电池储能电站的系统功率优化分配问题展开研究。面向电化学储能电站安全性的能量管理问题,提出考虑电池舱健康状态（SOH）及荷电状态（SOC）双层控制下的系统功率分配策略。首先基于SOH设计一级功率均分、单独出力以及自适应分配三种分配模式;然后,考虑SOC设计防止过充过放的分配策略;最后设计二级功率分配策略联动,在优先保障电站运行安全性前提下,同时提升储能电站输出功率分配最优,并分别从电池舱级、逆变器级、系统级三个方面设计算例验证有效性,为后续电化学储能电池系统的工程实际应用重要参考价值。

Abstract：The safety and stability of energy storage power stations during operation have received strong attention from the industry. Energy storage power stations of high power level cannot operate without many battery compartments. Reasonable power distribution is important to ensure the operation safety and improve efficiency of energy storage power stations. Therefore, the paper studies the optimal power distribution of typical lithium battery energy storage power stations. Aiming at the energy management problem of energy storage power station safety, a power distribution State of health (SOH)-State of charge (SOC) strategy was proposed. Three power distribution modes are designed under the first-level SOH power distribution strategy, namely, equal power distribution, independent power distribution and adaptive power distribution. Then, the SOC is considered to design the distribution strategy to prevent overcharge and overdischarge. Finally, the two-stage power distribution strategy is designed to improve the optimal output power distribution of the energy storage power station under the priority of guaranteeing the operation safety of the power station. The effectiveness is verified from three aspects of battery compartment level, inverter level and system level respectively, which provides important reference value for the safe operation of electrochemical energy storage power station system.

Key words： Power distribution energy storage power station safe operation energy management adaptive optimization
