摘要
风电高度依赖于风速,由于风速变化很大,因此会给电力系统带来严重的稳定性问题。为减小ESS(Energy Storage System)的成本和风电功率波动,提出了一种浆距角与ESS协调控制的方法,根据转速的大小,进行浆距角控制和ESS控制,在减小电网测风电波动的同时,能降低ESS的容量。在Matlab/Simulink环境下,搭建了风电系统模型,仿真结果表明,与传统ESS控制相比,功率波动下降了5. 6%,ESS容量降低了50%,证明了该控制策略在降低功率波动方面的有效性。
Wind power is highly dependent on wind speed,which is variable,so it would bring serious stability problems to the power system.To solve this problem,many power generation companies or grid operators start to use ESS(Energy Storage System).In order to reduce the cost of the ESS and wind power fluctuations,A pitch Angle of the ESS and coordinated control method are proposed.According to the size of the rotating speed,to control pitch Angle and ESS,decrease can measurement of fluctuation of wind power in the power system and reduce the capacity of ESS,in Matlab/Simulink environment,the simulation results show that compared with the traditional ESS control,power fluctuation has fallen by 5.6%,ESS capacity is reduced by 50%,The effectiveness of the proposed control strategy in reducing power fluctuation is proved.
