Description

一种单级变换的分散式电池储能系统 技术领域
本发明属于电池管理技术领域，具体涉及一种单级变换的分散式电池储能系统。
背景技术
随着化石燃料资源逐渐枯竭和环境问题日益突出，传统的火电面临巨大压力。随着人们环保意识的增强和国家政策的推动，越来越多可再生能源开始进入发电领域，例如风力发电、光伏发电、水力发电、生物质能发电、核能发电等方式。因为风电、光伏等可再生能源发电具有波动性和不确定性，随着这些可再生能源发电量的提升，大规模的高比例的波动性电力并网会给电网的稳定运行带来极大的挑战。如何保证电力供应和需求之间的平衡，如何保证电力系统的频率稳定和安全性、可靠性，已经成为目前亟待解决的重点问题。对可再生能源发电系统配备一定容量的储能装置，可以对电站起到调峰调频、削峰填谷，提高新能源的利用比率和能源的利用效率，保障电网的安全和稳定运行。
电池储能作为发展最迅速的储能模式，它具有能量密度高、能量转换效率高、响应速度快、调节精度高等优点。电池储能系统主要通过将电能以化学能的形式进行储存和释放，它可以在1s内完成AGC调度指令，有效提高电力系统的调频能力。尽管电池储能技术具在电力储能市场占有越来越重要的地位，但是目前电池储能系统在实际应用中还存在较大问题。电池储能技术目前普遍采用的是电池组串联成组然后再并联到一起的方式，这样的模式对电池的一致性要求很高，当一个电池模组发生故障或者起火的时候，对其他的电池模组和整个电池系统都会造成不可逆的损害。另一方面，因为目前储能系统热管控技术不完善，在运行的过程中极易导致电池模组间的温度偏差较大从而导致运行状态的不一致，从而导致故障的出现，甚至发生安全事故，引起火灾。
发明内容
为了解决上述现有问题，本发明的目的在于提供一种单级变换的分散式电池储能系统，具有高稳定性、高效率、高安全性且结构简单。
本发明通过以下技术方案来实现：
本发明公开了一种单级变换的分散式电池储能系统，包括电池管理系统、DC-AC模块、电池模组和储能集装箱；每个电池模组对应串联一个DC-AC模块，所有DC-AC模块并联后与电池管理系统连接，电池管理系统连接至外部电网；所有电池模组置于储能集装箱内，电池模组与储能集装箱之间、相邻电池模组之间均填充有防火材料；
DC-AC模块集成有BMS管理系统，电池模组包括若干相连的电池单体。
优选地，电池模组中的单体电池为串联。
优选地，单体电池为锂离子电池、铅蓄电池、钠硫电池或液流电池。
优选地，同一电池模组中的单体电池类型相同，不同电池模组中的单体电池类型相同或不同。
优选地，储能集装箱为防火材质。
优选地，防火材料中添加有阻燃剂。
与现有技术相比，本发明具有以下有益的技术效果：
本发明公开的一种单级变换的分散式电池储能系统，一个电池模组对应一个DC-AC模块，各电池模组与对应的DC-AC模块串联形成支路，将各个支路并联后连接到电池管理系统，电池管理系统的另一端直接与外部电网连接。系统中每个电池模组均独立运行，通过各自的DC-AC模块控制，可提高每个电池模组的运行效率，使整个系统具有高稳定性、高效率和高安全性。电池模组不再直接并联，而是在DC-AC模块侧进行并联，任意一个电池模组故障都不再影响其他电池模组正常工作，可以直接在系统中进行热插拔，大大提高了系统的利用效率；当一个电池模组发生故障时，可以实现系统不停机更换。通过DC-AC模块上的BMS管理系统，可以读取电池模组在运行过程中的电压、电流、温度等数据，通过这些数据来控制电池的工作状态，进行电池模组之间的平衡，提高电池储能系统的运行效率，提高 系统的寿命。
电池管理系统通过对电压、电流的分析可以计算分析得到电池的容量，可以依据这些数据来调配电池的充电和放电的优先顺序，保证电池的电量保持在均衡状态，提高电池的循环次数。通过温度数据可以实时监控电池模组目前的温度情况，当温度过高时，可以直接切断该电池模组，预防火灾发生，起到保护整个电池储能系统的作用。还可以对各个电池模组运行状态信息进行评估、对整个储能系统运行状态进行分析、对已发送故障的诊断和未发生故障进行预判、对电网所需功率信息进行实时监控，从而及时管理和调配电池储能的充放电状态，保证每个电池模组的电量基本保持均衡，并保证储能系统的输出功率达到电网调度的需求，并实现平稳的输出。此外，该系统内仅有单级变换拓扑结构，可直接实现储能电池模组与交流母线之间的双向升压降，其结构简单，变换效率可以达到97％以上，单级变换并联运行，可以支持更大容量储能系统的能量转换。该系统不会增加单组电池系统功率，并且电池系统可以做成模块化产品，便于扩展，冗余性高，且可以大大节约成本，提高系统经济性。电池模组与储能集装箱之间、相邻电池模组之间填充的防火材料能够在单个电池模组故障起火后保护其它电池模组不受影响，进一步提升系统的安全性和稳定性。
进一步地，电池模组中的单体电池为串联，单体电池间容量能够保持均衡，提高系统的稳定性。
进一步地，同一电池模组中的单体电池类型相同，一致性较高；不同电池模组中的单体电池类型相同或不同，均不影响储能系统的应用，可以扩大电池的应用范围，例如梯次电池的利用。
进一步地，储能集装箱为防火材质，防止起火后危及整个系统安全。
进一步地，防火材料中添加有阻燃剂，进一步提高阻燃效果，提升系统的安全性和稳定性。
