分布式电池储能系统在概率输入延时下的荷电状态安全均衡控制
Distributed state-of-charge secure balance control for battery energy storage systems under probabilistic input time-delays
摘要
Abstract
This paper investigates the distributed state-of-charge(SOC)security balancing control problem of battery energy storage systems(BESSs)in DC microgrids subjected to probabilistic input time-delay.Since the signals between the controller and the BESS unit are mainly transmitted through the wireless network,and the transmission distance is relatively long,the input time-delay is a major factor affecting the SOC balancing control.Therefore,a Bernoulli distribution random variable with known probability is introduced to characterize the phenomenon of the probabilistic input time-delay,and an improved distributed equalization strategy is proposed to achieve the SOC equalization control under probabilistic input time-delay.With the help of the Lyapunov stability theory,sufficient conditions for the consensus error system to realize the SOC equalization of the BESSs under certain constraints are established.Finally,a series of numerical simulation experiments verify the effectiveness of the equalization scheme.关键词
