摘要
为研究大容量的风电接入电网对电网运行稳定性产生的影响,建立了风电并网仿真模型,分析了在不同渗透率下,风电对电网电压及能量传递造成的可能影响。仿真结果表明在功率高渗透率下,风电的输出波动性将引起传输功率较大起落,对电网的电压稳定性造成很大影响,有必要对电网进行相应的运行优化和控制。
To study the influence on the stability of the network with grid integration of large wind-power.Modeling of wind-power grid integration is established to analysis the effects of voltage and energy transfer of the distribution network under various wind-power penetration ratios.The simulation results show that,for large wind-power penetration,the randomness of wind will make the energy and the voltage fluctuate greatly.And it is necessary to optimize and control the grid operation.
