【摘要】：储能为抑制风电功率随机波动性对电力系统的不利影响提供了可能。为减小风电功率随机波动分量对电力系统的影响,提出用储能设备平滑风电功率随机波动频繁的min级分量,并通过分析风电功率min级分量的波动特性,建立对应的储能容量优化配置模型。该模型在充分把握风电功率min级分量波动特性的基础上,以概率统计的区间估计理论确定储能系统的容量配置和最大充放电功率。该优化模型可以较小容量的储能设备改善风电功率的平滑输出,有利于减小风电功率随机波动性对电力系统的不利影响。仿真算例表明了该算法的有效性。
[Abstract]:In order to reduce the influence of random fluctuation component of wind power on power system, the energy storage equipment is proposed to smooth the min component with frequent random fluctuation of wind power. By analyzing the fluctuation characteristics of wind power min stage components, a corresponding optimal configuration model of energy storage capacity is established, which is based on fully grasping the fluctuation characteristics of wind power min stage components. The capacity configuration and maximum charge / discharge power of the energy storage system are determined by the interval estimation theory of probability statistics. This optimization model can improve the smooth output of wind power by the energy storage equipment with small capacity. It is helpful to reduce the adverse effect of random fluctuation of wind power on power system. The simulation results show that the proposed algorithm is effective.
