摘要: 储能系统成本高、控制技术不成熟,制约了电池储能系统的大规模应用。在充分考虑电池储能系统经济性基础上,该文提出了基于双向互补的储能系统控制策略。由2组电池构成双向互补电池储能系统,通过雨流计数法计算电池充放电深度(depth of discharge, DoD),以表征电池循环寿命,并建立了双向互补储能系统充放电控制模型。基于国内某光-储联合电站实测数据,在储能系统不同充放电临界荷电状态限定范围内,对双向互补电池储能系统控制策略的经济性进行了仿真分析。仿真结果表明,与单储能系统控制策略相比,基于双向互补的电池储能系统控制策略可以有效提高电池储能系统的使用寿命,降低储能系统成本,具有良好的工程应用前景。

Abstract: The high cost and immature control technology of energy storage system restrict the large-scale application of battery energy storage system. With full consideration of the economy of battery energy storage system, this paper proposes the control strategy for energy storage system based on bidirectional complementary, in which the bidirectional complementary battery energy storage system is composed of two groups of batteries. We calculate the the depth of discharge (DoD) by rain flow count method, in order to characterize the cycle life of the battery; and establish the charge and discharge control model for bidirectional complementaryenergy storage system. Taking the measured data of an photovoltaic-energy storage hybrid power station as example, we simulate and analyze the economy of the control strategy for bidirectional complementary battery energy storage system, in the different limited range of the critical state of charge during charge-discharge in energy storage system. The simulation results show that, compared with the control strategy of single energy storage system, the the control strategy of battery energy storage system based on bidirectional complementary can effectively improve the service life of the system and reduce the cost of energy storage system, which has a good prospect of engineering application.

Key words: energy storage system, bidirectional complementary, control strategy, economic analysis
