摘　　要：大量的风电并网会对电力系统的潮流、电压稳定、经济性能造成一定冲击,确定风力发电的最大接入容量是一个必须解决的问题。首先总结了风电并网的关键约束问题。在此基础上,将风电最大接入容量问题转化为潮流、电压稳定、经济性能等约束条件下的数学优化问题,最终利用基于相关机会规划理论的优化算法求解了风力发电最大接入容量。在39节点标准测试系统中进行了测试,算例分析表明本文提出的方法可以正确处理各种不确定因素,求解风力发电的最大接入容量。With the increasing penetration, the wind power will affect the power flow, voltage stability and economic value of the power syterm. It is necessary to investigate the wind power penetration level. The key constraints of wind power are firstly analysed. Based on detailed analysis of these limits, the calculation of wind power penetration level are converted to an optimization problem which is constrained by load flow, voltage stability and value of wind power. The dependent-chance goal programming algorithm is utilized in the calculation of wind farm size limits. Finally, the validity of the proposed model and algorithm is tested in the IEEE 39 nodes sample system. Results show that the proposed algorithm can deal with the uncertain constrains and calculate wind power penetration levels.
