一種基于微電網系統的BMS電池儲能管理方法及系統與流程

本申請涉及儲能智(zhi)能管(guan)理,且更為具(ju)體(ti)地,涉及一(yi)種基(ji)于微電(dian)網系(xi)(xi)統(tong)的bms電(dian)池儲能管(guan)理方法及系(xi)(xi)統(tong)。


背景技術:

1、隨著可再生(sheng)能(neng)(neng)源的(de)快速(su)發(fa)展和能(neng)(neng)源轉型的(de)推進,微電網系(xi)統作為一種具有分布式能(neng)(neng)源資源、靈(ling)活性高、可持續性強的(de)能(neng)(neng)源供應模式,受(shou)到(dao)了(le)廣泛關(guan)注。在微電網系(xi)統中,電池儲能(neng)(neng)技術(shu)扮演著至關(guan)重要的(de)角色(se),可以平(ping)衡電力供需之間的(de)矛(mao)盾(dun),提高系(xi)統的(de)穩定性和可靠性。

2、電(dian)(dian)池管理系統(tong)(tong)(tong)(bms)作為(wei)電(dian)(dian)池儲能系統(tong)(tong)(tong)的(de)核心(xin),負責監(jian)測電(dian)(dian)池狀態、控(kong)制充(chong)放(fang)電(dian)(dian)過程,并保(bao)護電(dian)(dian)池免受損壞。在微電(dian)(dian)網系統(tong)(tong)(tong)中,bms的(de)性能和(he)管理策略對于整個系統(tong)(tong)(tong)的(de)運行效率和(he)電(dian)(dian)池壽命具有重要影(ying)響(xiang)。

3、然而,傳統的(de)bms電(dian)(dian)(dian)池(chi)儲(chu)能(neng)管(guan)理方案往往忽(hu)視了充電(dian)(dian)(dian)過(guo)(guo)程對電(dian)(dian)(dian)池(chi)健(jian)康的(de)影響(xiang),過(guo)(guo)于追求(qiu)充電(dian)(dian)(dian)速度(du),導致(zhi)電(dian)(dian)(dian)池(chi)溫度(du)過(guo)(guo)高、循環次數過(guo)(guo)多等問(wen)題,從而縮短了電(dian)(dian)(dian)池(chi)的(de)使(shi)用壽命。此外,傳統的(de)bms電(dian)(dian)(dian)池(chi)儲(chu)能(neng)管(guan)理方案往往采用固定的(de)充電(dian)(dian)(dian)策略,無法根據(ju)電(dian)(dian)(dian)池(chi)實時狀態(tai)進行動態(tai)調整(zheng),這樣可能(neng)導致(zhi)充電(dian)(dian)(dian)速度(du)過(guo)(guo)快或過(guo)(guo)慢(man),無法有效平衡快速充電(dian)(dian)(dian)和電(dian)(dian)(dian)池(chi)健(jian)康之間的(de)關(guan)系。

4、因此,期望一種優化的基于(yu)微電網(wang)系統(tong)的bms電池儲能(neng)管(guan)理(li)方(fang)案。
