| 从维持微电网安全稳定运行,延长蓄电池使用寿命的角度出发,提出一种改进型混合储能控制策略,通过将待平抑功率
分解为高、中、低频段 3 种分量,引入储能系统 SOC 的反馈来设计混合储能功率分配策略,减少蓄电池充放电次数,延长其使用
寿命,同时防止储能系统出现过充/ 过放现象,使混合储能稳定安全响应电网能量调度。 实际算例证明,与传统控制策略相比,
在相同工况下改进型控制策略使蓄电池充放电次数降低了 58. 3%,并且能够有效解决由于储能设备的过充/ 过放而导致系统不
能正常稳定运行的问题。 |
| 英文摘要: |
| From the perspective of maintaining the safe and stable operation of the microgrid and prolonging the service life of the battery,
an improved hybrid energy storage control strategy is proposed, which is designed by decomposing the power to be stabilized into three
components in the high, middle and low frequency bands, and introducing the feedback of the energy storage system SOC. The hybrid
energy storage power distribution strategy reduces the number of charging and discharging of the battery and prolongs its service life. At
the same time, it prevents the energy storage system from overcharging / overdischarging, so that the hybrid energy storage can respond
stably and safely to the grid energy dispatch. The actual calculation examples and the comparison simulation experiment results prove
that: compared with the traditional control strategy, the improved control strategy reduces the charge and discharge times of the battery by
58. 3% under the same working conditions, and can effectively solve the problem that the system cannot operate normally and stably due
to the overcharge / overdischarge of the energy storage equipment. |
