基于SOC优化的混合储能平抑风电波动方法
Method of Hybrid Energy Storage to Smooth the Fluctuations for Wind Power Based on State of Charge Optimization
摘要
Abstract
According to different energy storage characteristics of batteries and super capacitors,wind farm output power signals are decomposed by wavelet packet to obtain the reference powers of batteries and super capacitors during charging and discharging.The power allocation optimization methods based on the state of charge (SOC) of batteries and super capacitors are proposed,and all working conditions that may occur when the two energy storage components operate with coordination are discussed in detail,With the real-time detection of SOC,the reference powers of the energy storage elements during charging and discharging are adjusted in abnormal working conditions,and over-charging/ discharging protection can be taken in time..The proposed method is effective to stabilize wind power fluctuations,and it can also stabilize and extend the life of batteries and super capacitors.The simulation model built in Matlab / Simulink verifies this control method.关键词
