|
摘要
风储配合是平抑风功率波动的有效途径,时滞给风储系统控制策略的运行效果带来了不利的影响。分析了风储系统各环节的时滞对功率平滑策略产生的影响,并提出了增加系统指令更新周期的解决方法,在Matlab/Simulink平台中对该方法进行仿真,分析了不同的系统指令更新周期对风储系统风功率平抑控制策略运行效果的影响。仿真结果表明,系统指令更新周期为系统平均时延的2倍时,可以保证平抑风功率控制策略的有效实现。将该结论应用于实际风储系统中进行论证,仿真结果和实际风储系统运行情况均表明了该方法的有效性,可以为风储系统平滑功率等相应策略的设计提供参考。
Wind storage coordination is the effective way to stabilize wind power fluctuation,and time delay has a negative impact on the operation of the wind storage system's control strategy. This paper analyzes the impact of the time delay of each section in the wind storage system on power smoothing strategies,and proposes the solution to increase the system instruction update cycle. We simulate the method on the Matlab /Simulink platform,and analyze the impacts of different system instruction update cycles on the running effect of wind power smoothing control strategy of wind storage system. The simulation results show that,when the instruction system update cycle is twice the average time delay of the system,it can guarantee the effective implementation of the wind power smoothing control strategy. We apply the conclusion into the practical wind storage system,and the simulation results and the operation condition of actual wind storage system both show the effectiveness of the method,which can be a reference for the design of the smoothing power and other corresponding strategies of the wind power storage system.
