提出了用随机潮流计算分析风电场并网所引起的系统电压波动的方法.该方法全面考虑了风电场出力变化、负荷波动、发电机停运以及线路故障等随机因素
通过随机潮流计算求出风电场并网后系统各节点电压的概率分布
其中特别包括风电场接入点的电压波动情况.在此基础上
该方法可以对风电场的无功补偿进行进一步分析.此外还证明了用三参数的Weibull分布描述风速变化可以更好地反映高风速对风电机组输出功率的影响
对于常年风速较高的风电场更适合采用此分布描述.对接有风电场的IEEE RTS 24节点系统进行的算例分析证明了该方法的有效性
并通过实例说明了如何利用该方法指导对异步风力发电机的无功补偿.
A new probabilistic load flow model to investigate voltage fluctuation caused by wind farm integration is presented.Considering wind speed randomness and other stochastic disturbances
such as varying loads
generation unit and branch outages
the probabilistic distributions of constraint violation of node voltages and branch transfer powers can be obtained
then the enduring ability of the integration node for the stochastic wind power generation
the reactive power compensation and the integrating equipment effect on the voltage fluctuation can be analyzed thoroughly
which provide a useful tool for electrical engineers to reveal the voltage quality of the gird and choose the integration node for a wind farm. The three-parameter Weibull distribution model taking location parameter into account is proposed to describe wind speed random fluctuation. Compared with the normal two-parameter Weibull distribution model
the impact of the high speed wind on the power output of the wind turbine is considered in the presented model
thus more satisfied results can be obtained in the evaluation. The calculation of voltage fluctuation has been preceded on IEEE RTS 24 test system integrated with wind farms.
