摘　　要：在全球能源结构转型的加速推进中,新能源发电在能源供应中的地位日益凸显,然而其发电过程中容易受到外界自然因素的干扰,新能源电力系统往往存在供电中断或波动性较大的问题,对电网整体安全稳定供电造成不良影响。储能技术作为新能源电力系统中平衡电网负荷、保障电网稳定性的关键手段,对于维护电力系统稳定、保障能源安全至关重要。然而,储能系统面临的安全挑战亦不容忽视,随着储能电站装机容量的不断提高和电池串联电压的升高,其危险性也越来越大。为此,从能源安全入手,在新能源电力系统中引入主动安全的储能技术,旨在通过主动风险源辨识、主动故障预防、主动事故联动技术、主动EMS、主动PCS、主动BMS及主动智能巡检等多维度储能技术,解决系统供电的技术缺陷。同时,这些技术共同作用于新能源电力系统的全生命周期管理,形成主动安全管控能力,确保储能电气系统及储能电池系统的安全稳定运行。In the acceleration of the transformation of the global energy structure,the position of new energy power generation in the energy supply has become increasingly prominent.However,its power generation process is prone to interference by external natural factors,and the new energy power system often has the problem of power supply interruption or high volatility,which has an adverse impact on the overall safety and stability of the power grid.Energy storage technology,as a key means to balance the load of the power grid and ensure the stability of the power grid in the new energy power system,is very important to maintain the stability of the power system and ensure energy security.However,the safety challenges facing the energy storage system cannot be ignored,and with the continuous improvement of the installed capacity of the energy storage power station and the increase of the battery series voltage,the risk is becoming greater and greater.Starting from energy security,this article introduces active safety energy storage technology into the new energy power system,aiming to solve the technical defects of system power supply through multidimensional energy storage technologies such as active risk source identification,active fault prevention,active accident linkage technology,active EMS,active PCS,active BMS,and active intelligent inspection.At the same time,these technologies work together to manage the entire life cycle of the new energy power system,form active safety control capabilities,and ensure the safe and stable operation of the energy storage electrical system and energy storage battery system.
